Thanks so much! When researching this video, I couldn't believe no one has ever pitted these two cars together, especially as the LT4 was essentially a replacement for the LT5. After running this test, my personal conclusion as someone who likes to daily their Vette is to save up and go for a late-model ZR-1, which I think is the best of both worlds! Its an intoxicating sound for sure.

​@RetroCarsForever have you thought about getting a guy who tracks cars to test the ZR-1 with modern performance tires like Pilot sport 4S? Back in the 90s the original tires were basically all seasons. I'd love to see lateral g tests. Plus the look on your face when holding on mid corner would be fun to see 😅

Well, both of these cars have pretty aggressive modern rubber. No All Seasons here (though my C4 originally had All Seasons, you can see in some of the older shots from older car shows, I replaced them with Continental Extreme Contact Sport summer performance tires just in time for the actual comparison test). Big difference in grip for sure!

@@RetroCarsForever Me being 50yrs old, thank you for this. I graduated HS in 91 and the ZR1 was a savior to me but in 96 I loved the GS and the manual 5.7 LT4. always wondered who would win.

@johnhenry267 You're very welcome, glad you enjoyed it!

Awesome! Would love to hear your thoughts between those two cars once that ZR-1 is up and running. What chip is in your LT1?

@@RetroCarsForever Not sure. It came installed when I bought it. I didn't even know about it until I was as chasing down a bad optispark. I pulled the chip out seeing if it was the issue and there was a noticeable difference in power.

I purchased a base 1993 Corvette a few months ago. I noticed the car sitting for a year or so and finally decided to stop and check it out. Turns out it had a for sale sign behind the windshield that had fallen. The interior looked decent overall but, the body was in rough shape from sitting, but decided to call the number on the sale sign. The owner told me it ran but the transmission was bad, probably 4l60 issues or tv cable adjustment. I bought it, towed it home and made a few posts/calls. My friend buys and sales cars on the side and had a spare 4l60e from a pickup laying around. I made the necessary mods to get it in the car and to my surprise it worked. I installed a micro controller from eBay since the car has no provisions for electronic transmission control and didn't want to drop the coin for a transmission controller not knowing the state of the transmission at the time. I installed the trans go vac-46 mod to control the transmission pressure since the max line pressure was causing very firm shifts. Before I purchased the car I watched a few videos from this channel that pushed me towards the car. I wanted a c6 grand sport, but ya know, life. Overall pleased with the cars performance even though it has a ton of maintenance to be done.

There’s a ‘91 ZR1 near me for $15k with 111k miles. Paint is a little faded. If I could get it for something around $12k I would be over the moon

I've got two types of pickles. Dill and bread & butter.

Thanks so much, awesome to hear from an owner such as yourself. After finally driving a ZR-1, I get the appeal...It was, at the time, probably the best car in the world! And as much as I love my LT4, I dont think it can make that claim. The history of the Z and the street cred truly make it shine. I definitely want to own a (later year) ZR-1 someday!

@@RetroCarsForever The ZR-1 community would welcome you with open arms. And keep Marc Haibeck in mind when you get one. He took my car to just over 500 hp. It's an absolute riot to drive.

@@JP-yf1cf Thank you! Researching the Haibeck chip for this video, it's definitely something I would be interested in...For me, less about power and more about drivability and longevity.

Rookie talk

Not quite lol. The 93+ ZR1 was way better. John lingenfelter said the cams we're off by as far as 5°! Just degreeing them right picked up 50hp! And that's before adding headers which added another 30! John lingenfelter is the reason Chevy came out with the LS7! Lingenfelter did it first. Then Chevy followed! He should be accredited with the 427 Small block! Rip John.

Yeah, no idea where the 2k they are using came from

So what exactly are you disagreeing with?

So much false info

Ha, happy to help make your decision with this video then! I also couldnt believe this matchup has never happened in the past three decades, especially as the LT4 was essentially the LT5's replacement, so it was a blast finally making this comparison come true. Better late than never!

@@RetroCarsForever Thank you!

After driving both, I'd love to own a late-model ZR-1. Expensive, but best of both worlds really. And agreed, there's something about the low/wide stance of the ZR-1 that's understated and badass!

That heinie is soooo awesome. Baby got back!

Lloyd Elliott top end, cam, and 396 cid stroker build. Lt5 is lunch. And for the money saved, you could build the hell out of that LT4 car.

Thank you! I had to look up the LT4 Firehawk (www.motortrend.com/features/1997-pontiac-firehawk/), never heard of that one! What a rare bird you have, that's so cool. Cool to hear your personal findings on these cars mirror what I found in this test. That LT5 sure draws a crowd!

@@RetroCarsForever Yeah, the LT4 Firehawk was definitely rare, kind of wish I'd kept it. I actually went from the LT4 Firehawk to a lightly modded 91 ZR-1 many years ago, the LT4 had better low end to midrange torque, while the LT5 just keeps pulling on the top end. Two very different ways to make power, with the LT4 being better for typically around town and daily driver use, while the LT5 is really better when you can open it up and stay in the throttle all the way to redline.

...and dat biiig azz....

@@RetroCarsForever They also made a few 1997 LT4 Camaro SS.

That Corsa exhaust sounds mean, but the Billy Boat has sexier exhaust tips. I've been debating between the two for a while.

😆

AMEN🎯🎯🎯🎯🎯🎯🎯🌟👌🏾‼️

That probably explains the high divorce rate 😂

​@@fastc4zr-1😆

So either way you're stuck with something that'll drain your wallet but feel good to get behind....

Thank you! LT4s UNITED!

We talked about that, but wanted to emulate how an owner would actually drive/launch their car in the real world. Dropping the clutch at 3000/3500 is way higher than most owners would ever be comfortable doing as it's hard on the cars, so we settled on 2000 rpm instead. Also, we actually did around 5 acceleration tests for each car (only showed the last two in the video), so we didn't want to burn up our own cars too bad.

He didn’t want to spank his LT4 too hard. 😂

Cars are made to be drivin .If ya break it, ya fix it

Thank you for watching!

Wow, thank you SO much! And agreed, familiarity with the mechanicals of an old car like any C4 is paramount to a happy ownership experience. I will say after doing research that I dont think the ZR-1 is the scary monstrosity that people make it out to be, even if an LT1/LT4 is way simpler and cheaper to deal with.

@@RetroCarsForever well that's good news that the ZR1 is easier than I feared! makes it all more valuable. As i was watching your video I found it pretty funny how your '96 had the ZR1 rims but the ZR1 had '91-96 rims! Do you know when the ZR1 changed to the 5 spoke style?

Brad I have both of these and your analysis is spot on. ZR-1 is a unique experience, specifically the sound of the high reving engine at 5 to 6.5k

Thanks, great to hear! And yes, the LT5 engine sound is SOMETHING ELSE when it gets revved up. Intoxicating mix of good ol' American V8 muscle with the high revs of an exotic. Love it! @@anthonygrisolia8403

Thank you! I kept seeing this topic come up in C4 circles as well, and when I got my LT4, was even more curious to find out. Couldnt believe there was never a back to back comparo in three decades, so that meant I had to be the one to make it happen, which was a joy to put together. Thanks for watching!

I like to see the Grand Sport go next to a ZL1. They both have the wider tires on them.

I would be happy to put my Grand Sport up against a ZR-1.

Right on! Glad you enjoyed the comparison and that it was worth the wait. And congrats on getting your dream car, I know the feeling, and it's a GOOD one!

Thanks for stopping by! If you're curious to know more about C4s, you could also check out my C4 Buyer's Guide here- kzfaq.info/get/bejne/hJZyisKFq-Cvnps.html

Thanks Brian! I'm pretty proud of this one, I think it struck a nice balance between fun and informative.

For me its the 1993 ZR-1 since it has the best seats, retains the glove box and got the upgraded 405hp LT-5 Motor. Only downside is it didn't come with the best colour options and the most common one is that dull looking Ruby Red.

@kimblem.w9952 I have the same seats in mine the optional leather sport seats and mine has the glove box as well lol it also has the FX3 suspension. The sport seats came standard in the ZR1 I believe.

@@C4VETTELT1 they do but the overall seat design changed in 1994 and the side bolsters weren't as aggressive. I think they also used better leather in the older seat design imo.

@@kimblem.w9952 I believe Dark Rose Metallic offered in 93 with the dove grey interior is as good as it gets for C4.. Dark Rose was offered again on 2017 C6. I get complements often when filing up....not about the car but about the color.

The ‘96 GS is a real gem.

Thank you, and agreed on all counts! I bet a 1995 ZR-1 would be better in every way than that 1991, BUT they are in a totally different price class to the LT4 (they're 10 to 15 grand more), so it didn't feel like a fair fight. And yes, best bang for the buck is an LT1 with some mods (especially rear end gear swap).

There's nothing similar other than the "LT" moniker between the two gens of engine families other than they're small blocks. The new LTs are basically direct injected LSs.

@@zztop7306 the one main thing that is similar between the LT1/LT4 and current Corvette motors is that GM decided to bring production in-house. They didn't need to go outside for the Corvette's highest performing motor. The LT5 was developed back when the L98 was only making around 240 hp. The LT1 helped bridge that gap and was way cheaper for Chevy to produce in-house.

Thank you, and welcome to the channel, I've filmed a ton of C4 videos if you're interested (here's a playlist) kzfaq.info/sun/PLZVytpvgg5yfaAocNPR3Zu-ckM5DAAgk0 After driving this ZR-1, I do think it's a car I HAVE to own one day.

Get one! Mine was 39K and with 9k miles that’s about the norm. You were spot on on your market prices. Keep cool vids coming!

Thank you! And agreed.

One of the most challenging characteristics of a car is to obtain incredible handling. Much easier to make HP. Given that, the LT1 Z07 would be my choice of C4s!

Thank you! I had to verify that no one had ever publicly compared these two cars before, and couldnt believe no one had in 30 years...So I'm glad I was able to finally make it happen. Glad you enjoyed it!

Thank you! I feel ya, the C4 was the Corvette of my childhood as well. As cool as later Corvettes are and as many of improvements they made (especially with the C5 which was a quantum leap forward), I feel the MOST nostalgia for the C4 and it's classic style.

Thank you! A 1996 LT1 Auto is still a ball to drive. After doing this test, I want to save up for a late model ZR-1, which I feel would be the best of both cars (just pricey and hard to find one!)

I did consider doing a "highway roll" test, but couldnt find the filming time to make that happen, as well as pushing safety concerns. I do suspect the ZR-1 would've had even more of an advantage.

Nice! Truly, a world-beating car that Americans could be proud of.

I couldn't remember if it was Alien or "The Thing" that the engine reminded me of. That thing that attached itself to your face before killing you.

That’s where I got that clip from! Legendary.

Wow, that's fast for a 92 auto! I'm curious, how have you tested your car and your where?

@RetroCarsForever just like you on a country road with a timer lol mine is pretty far from stock. I haven't retested yet after I did the headers.... but I got full custom exhaust system from headers to tips ( its an intermediate pipe and secondary cats from a 2017 grand sport Frankensteind in with the C7 cats also) built 700R4 stage2 shift kit but like I said it's shifting into 2nd at 4,800 RPM so the 0-60 time will improve when it's shifting when it should.

Wow, that's FAST! As I mentioned in the video, a country road is not gonna be anywhere near drag strip or test area times. So your car could likely run a mid 4 sec time on a proper surface.

@RetroCarsForever I was thinking about the same but also shifting correctly. Shifting into 2nd at 4,800 is not cool!! Lol but it makes enough tourqe it kinda just powers through it.

My 85 L98 with 3.07 rear end at about sea level will hit 60 around the low 5's, my best 60' at the strip was a 1.84. That altitude makes a world's difference. Very simple bolt ons and a newer ECM Swap.

Cool to hear that you got similar results to what we achieved in our test!

@@RetroCarsForever y...you tasted them?

@@nunyabusiness896 Ha, autocorrected that into a weird sentence didn't I! 😆

Once my friend got his ZR-1 I was curious about how it would fare against my LT4, especially with the legend that the LT4 is underrated. Couldn't believe that in three decades no one had done this comparo before, especially as the LT4 was basically the LT5's replacement. So, I knew I had to make it happen, and it was fun doing so!

Thank you, I appreciate it!

I'm curious what journalist said that about the ZR-1, having read all the reviews from the major car mags of the era they were almost all glowing (except for that super high price). Having the LT5 made outside of Chevrolet likely added to cost (Lotus designed and Mercury Marine assembled). Do you have a C6 Z06 or a C6 ZR-1?

@@RetroCarsForever It was so long ago, it's kinda hard to remember... It might've been Automobile Magazine when David E. Davis was running it...I think...I remember being struck by the remark. As you guys mentioned, the C4 had its interior noise issues. And I believe that's what lead to that comment. Z06. I decided I didn't want the extra complexity & issues of forced induction. I love the throttle linearity & super instant throttle response of the LS7. It's a perfect compromise, imo. After 10+ years, I still feel I made the right choice. It's just a 1LZ. Was trying to keep it as light and simple as possible....

Yep, the only mechanical difference between the Grand Sport and my Z51 LT4 are those wider rear tires (at least on the coupes, convertibles had the normal rear tires)

Thank you! I'm also amazed at how far we've come, power wise. Just to use the Corvette as an example, the base Corvette power output essentially DOUBLED from the beginning of the C4 to the beginning of the C6!

Thank you, me too!

Thats awesome! I actually wanted a Polo Green LT4 but couldn't find a nice enough example when I was looking (so went with this Collector Edition instead). It's a great color. I'm sure kids love seeing the pop up headlights in action too, considering that's something they dont see anymore either!

Awesome, LOVE hearing comments from people who actually own both cars! Sounds like your Z is a ultimate "weekend" fun performance car, and your LT4 convertible is a great smooth cruiser.

Thank you!

Thank you! You bought almost exactly what I have it sounds like, obviously I think it's a great choice. And I was honestly a skeptic of the LT4 underrating legend, until this test. While I dont think my test alone is conclusive, I think it adds to the pile of evidence already out there.

How much did you pay if you don’t mind me asking? I’m looking at a LT4 ce vert with 34k

@@michaelcooper9528 I think I got a really good deal. I paid $17k. It needs a few small fixes but runs amazingly. See @RetroCarsForever for his videos on the common issues.

Thank you, hope so too!

Thank you! Black rose with white interior is one of my favorite C4 color combos. As for gas mileage, I didn't mention it because by all accounts they appear to be pretty much the same (which would make sense as both engines are the same displacement).

Agreed, I've seen thousands of C4s in my lifetime, but I think this is the only Steel Blue example I've ever seen in person.

Sorta, earlier base C4's had the top 3rd brake light as well. But yeah, on "round butt" cars, great identifier if you're in the know.

Thanks so much! Glad you enjoy them.

Same here!

Thanks! And I love your logic...It's not like an LT1 is a slouch either. Off the line it's just as fast as an LT4, I only really notice the LT4's higher bandwidth when I'm racing around the canyon roads.

Thank you! And same here.

Thank you! Glad you enjoyed it.

Thank you! I actually already mentioned that amazing 24 hr record in my C4 Special Editions video here- kzfaq.info/get/bejne/rL2YqrF8mrLPqZs.htmlsi=6xws48kAddIvjYdC

I shifted right at redline with both cars. In any case it’s super cool that you’ve had your ZR-1 since new!

Thank you, will do!

Great times for those cars! I would love to do a comparison test between a C4 and C5. I've driven several C5s and agree they're better cars in most ways, I just have more nostalgia for the C4 and how it looks.

@@RetroCarsForever Ha.... I do all my own work too. That C4 was a pain in the rear end to work on. Except the clamshell hood allowed for easier access. The C5 is just much more designed to be driven and worked on. Also... that C4 had a weird rear end hop when cornering really hard over uneven pavement? My 04Z is rock solid and can out corner my abilities to drive 🙃

Thank you! I totally forgot that you could drive both C4s in GT5. Gotta dig up my old copy!

Wow, that's gotta be a beast! Do you know how much power it has now?

@@RetroCarsForever Yes, it Dyno to 813 HP and 844 TQ Engine Dyno, not chassis

Thats a good one! I bet the gap between those two would be even closer, at least to 60...The LT4 really comes onto its own in the upper rev range.

@@RetroCarsForeverThe LT4 was underrated. I used to run around with the F-Body and Corvette guys having owned both. Every LT4 I saw dyno'd was putting out only a couple of HP over or under 97 LS1s at the time. Not only were the C5 guys upset about this, but they were even more upset they were pretty much in the noise with the 98 F-Body guys as well, that their Corvette LS1s didn't put out more than their F-Body counterparts. I understand the LT4 was a 350hp engine in reality but the 97 LS1 was only 345hp, so GM underrated it to not overshadow the newer engine in the next generation. The LT4 was a different beast from the LT1. I had a 97 T/A with an M6 and it felt like it ran out of breath at the top end. My LT4 I hit the rev limiter on occasion if I wasn't paying close attention because it felt like it wanted to keep pulling hard. IIRC, some folks pushed the rev limit to 6500 on these with programming and it still didn't run out of breath. From what I remember, the LT4 was built with factory race catalog parts, everywhere it mattered from the crank to the timing chain to be strong, to bridge the gap between the 95 ZR1 leaving and the 97 new model and engine that was coming. It was feared that GM couldn't sell any Corvettes in 96 if they didn't offer something unique in the ZR1's absence. I also read the ZR1 was dropped for 96 due to GM not wanting to make the investment in getting the LT5 ODBII certified, and that if the LT5 had continued, GM and Lotus planned to push the car to 500hp eventually. I still have my LT4, owned since 2002 but I'll have to get rid of it before much longer and go with something in an automatic as a weekend toy. I love the car but my knee can't take the truck-like effort of the clutch in these older vehicles anymore. I don't drive it anymore because of that. I also can't bring myself to get an automatic either as it just doesn't feel right. My first Corvette was a 96 LT1/A4 and while it was a Corvette, I just didn't feel right in it being an automatic. I'm thinking an 09 XLR or 13 Mercedes SL550 as a retirement toy, something that's a hard top convertible as I miss having one of those too. I'm old now, in my fifties, so I guess it's just the natural progression of things. On the negative side, the later C4s seemed to suffer from GM's cutbacks. Both my 96s felt like junk when you took the targa top off, heard the term "flexy flier"? The 80s C4s I drove felt pretty solid to me with the targa removed. I also believe when you mentioned the ZR1 felt better on the canyon roads, that it was due to extra bracing the ZR1 cars got that the base Corvettes didn't get. I don't believe the ZR1 had any complaints with the top off. One thing I worry about in keeping one of these around so long is that I understand you can't get the dual-mass flywheel anymore and that it's a different experience, and a noisy one when you switch to a single mass flywheel. I believe all the LT1/LT4/LT5 cars have the dual mass flywheel.

@@Shadow_Banned_Conservative Agreed with all your thoughts! I am surprised about the chassis stiffness comparison, as haven't driven an early C4 with targa off back to back to compare. Also wasn't aware of any significant chassis bracing with the ZR-1, didn't remove the top to see on that one either. I do know my 1996 has noticeably more flex with the targa removed! So I usually leave it on.

@@RetroCarsForever UGH, this thing ate my long response, don't have the energy this late to retype it out. Abbreviated version. I can't find the reference now to the ZR1 chassis differences. I came across a picture of the C4 frame a long time ago that I remember having the ZR1 differences highlighted by using a different color. I'll see if I can dig it up maybe on the long holiday week. I had quite a few Corvette books back in the day, so I might still have the reference I mentioned. Also, huge difference in chassis stiffness between my 96 and my friend's 87, I drove both back to back with the tops off. I still have it in the garage, but there used to be a company called "R&D Racing" back in the 1990s. They built and sold a very beefy convertible style X-brace. The convertibles came from the factory with a flimsy, stamped-steel I believe it was X-brace. The coupes have the mounting bolts drilled and threaded for the front but we had to use something called a "nutsert" and drill the holes in the rear of the frame to mount it. It cut a lot of clearance, but it really stiffened it up with the top off, and even noticeable when it's on. I don't think R&D Racing is around anymore. One mod I made to my 96 was adding replica ZR1 wheels to it. Even without the body work the 11" wheels will fit under the rear and the tires will come just flush with the fenders. The 96 Grand Sport came with 11" rears but GM used some stick on fender extensions to help hide them. I think it looks cleaner without, but they do fit. It definitely hooks better with the wider 315s on the back.

Thank you! Corsa cat back exhaust is probably what you want to get a great sound without too much drone. I tried simple Magnaflow mufflers on my car when I got it and the drone was so bad I went back to stock (my experience here)... kzfaq.info/get/bejne/oZ6kasKJyb6rqZs.html

Got it, thanks for answering. I'll wait to spring comes back around and stack a few bucks and make a decision. Love the Corvette community!!! @@RetroCarsForever

Thank you! There's a lot that sucks living in California, but the access to incredible roads makes it worth it. Probably not a lot you can do with a ZR-1 in metro Detroit beyond the occasional highway pull I suspect! Agreed, maybe it's time for you to take a road trip!

​@@RetroCarsForeverwhat about the intersection take overs 😆

Awesome! I'm super curious to hear what he thinks about this video. What a collection he has!

Best of luck in your search! Good ZR-1s are not easy to find, especially for a good deal.

@RetroCarsForever luckily high mileage doesn't scare me :)

Thank you!

Thanks! But how could the shifting be better? I definitely didn't want to "power shift" like the GM test driver you see in the video (not letting of the gas during shifts just seems too abusive and not how a "normal" Corvette driver would operate their car)

Interesting, I double checked exactly what the performance chip did at the 4:00 mark, doesn't look like it changed the secondaries function. I also checked with a few other friends who have ZR-1s who also claim their car has a pretty "linear" power delivery. It is a subjective feeling, but I also wonder if driving the car at a higher altitudes "smoothed out" the secondaries. Agreed with your "more playful" thoughts on the LT4. On a very tight canyon road, or on a tight autocross course, I do think it would be more lighter and more fun, and less intimidating. On the more open canyon roads that we drove on, the ZR-1 seemed to have the edge. And yes, the LT5 just LOVES to rev, it dares you to go faster in a way the LT4 does not! In any case, I appreciate hearing comments from someone who has owned both cars, thank you!

Awesome! I've driven plenty of C5s and even though I think they are awesome cars, I totally get what you're saying about how much BIGGER they feel (because they are!)

Thank you! And yes, I'm curious how a Grand Sport would've fared with its fatter rear wheels, certainly would've narrowed that gap.

Thank you! Congrats on the 40th!

Glad you enjoyed this battle of the Chevy titans!

Thanks! I do think a later-year ZR-1 is the best of both worlds, and the one I want to personally save up to get. Problem is later ZR-1s are WAY out of the price range of this $20k ish comparison test, which seemed unfair.

Same here!

Thank you! And yes, seems we share nostalgia for those wonderful car magazines of the 90s. I still have hundreds of them in my collection!

Thank you Terry, always happy to spread automotive joy!

Thanks man! Out of curiosity, why did you end up choosing the LT5 over the LT4?

@@RetroCarsForever Well I grew up riding in my Dad's '90 convertible 6 speed L98 Corvette and it made a lasting impression on me. After the accident in the '95 Firebird, the current owner had me test drive it and he wanted to see if I would buy it. The car needed a lot of TLC at this point so I decided I would hunt down a different '90 Corvette. '90 is my favorite year because of the one year only wheel design, the older exterior look, and the fresh interior. When buying a 1990 Corvette, you might as well get the ZR-1! I previously had seat time in L98, LT1, and LT4 Corvettes. My first time with the LT5 was the day I bought my ZR-1. What a car! I have nothing against the LT4. I just decided to get the ZR-1. I do like the exotic feel of the motor and the car show attention it receives.

@@FirebirdDude Great reasons! And agreed...The performance difference between a base 1990 and a 1990 ZR-1 is pretty significant! In later years that gap got narrowed quite a bit.

Heh, I guarantee under these conditions (high altitude, hot weather, slick surface) a V6 Camry would've fared MUCH worse!

Thank you! And totally agree...The magic of Corvettes is their bang for the buck (as well as their everyday usability). And as the years go on, they have only become BETTER deals, especially when you compare their current values to the insane prices of their import competitors of the day (which are much more rare). I'd even go so far to say that, for the money, you can't buy a better all around sports car than either of these two C4s.

Not just that, the C4 ZR-1 actually held track records for a production car, beating the 911 Turbo, and even the Ferrari F40 on some tracks

Thank you! Pretty cool to know that there's a C4 ZR-1 driving around Spain!

Thank you! Based on my experience and my research, I don't believe that MOST LT4's were putting out 380 hp, at best maybe a small percentage had that kind of power. I stick by my estimated guess that MOST were putting out somewhere around 350 hp.

​@@RetroCarsForever You can be absolutely correct on what most are putting out, but if a car is measuring 350HP on a typical dyno (at the wheels, where the common person is measuring), it is definitely about 10% higher at the crank, where the MFG is measuring. it is common for vehicles to experience power losses from the engine to the wheels due to mechanical inefficiencies in the drivetrain. Usually around 10%-15%. You dont need to take my word for it, just look it up. And by the way, no disrespect at all. Your video was great and i already shared it.

Thank you! Glad to hear I’m not the only one who hoards old car mags 😂

Thank you! And agreed, as if the LT5 wasn’t enough being a technical powerhouse, it also LOOKS fantastic too.

Awesome! Obviously I think that's a great spec.

Thank you! Glad you enjoyed it.

Thank you! I was also surprised no one has done this comparo in 30 years...Especially considering the LT4 was essentially the replacement for the LT5. So I knew I had to do it! I'm with you, I think my next C4 has gotta be a ZR-1, preferably a late model version for more daily refinement and power.
