Where is this magic junk yard with all the bbc engines? We don’t get that in the Midwest

So ultimately a Gen 6 with some head porting an slightly more compression and that same 274 roller cam should be a screaming runner, almost 500hp and tons of torque

I love the enthusiasm and excitement from your voice it's so encouraging

So, the moral of the story is, the gen 5 would be a perfect platform to turn into a 496 with some AFR 265 heads. Apply boost as-needed until either your block cracks, or your lips crack from all the smiling.

Thank you for the video and endless knowledge we appreciate all you do for us 👍 thanks for sharing

Thank You for Sharing to update my 1980s head choices!

Real Master in 454 Ireally learn alot from you videos i am build my 1983 gmc 454 engine i really see alot of info that i learn from your videos worth alot thanks Richard Holdene

We’ve learned they both need BOOST😉

Love the big block. I would like to see a 396/402 in basic stock then bump it up a bit. The 402 just might be the least expensive in the low deck BB.

Buddy of mine has a 454 SS pickup, he's putting on oval port heads and a cam/springs, but is sticking with the factory intake and throttle body system. I'll have to show him this video to try to change his mind on it, this really shows how much that intake is holding back the stock Gen 5 motors, and the problem will get only worse as the rest of the motor gets better.

They would make good daily's in a 3/4 ton truck... Low buck that's for sure Great Video

Hi from Australia love ya work .

Prediction- Awesome vid!

This is good info. Thanks for the video. My renter has a gen 5 454 with at least 350k and probably closer to 500k, as the odometer broke at 350k about 20 years ago. The old girl has a bad fuel pump and the trans has wiring issues but she runs good considering how many miles this truck has on it. I want to do something with the truck, but money and time is making something like a rebuild tough. We'll get around to it someday. It's a sentimental truck for him so we do need to get it back on the road but she's tired with an estimated 500k.

Finally some big block content

I just bought a 454... how would I tell which 454 it is and it got they feel injection intake on it just like the one you showed in the picture... and I love how you explain and break all your work down that helped a lot thank you❤️💪🏾💯

I smashed the link button - great to see Big Blocks again!!

That's good stuff. From the Summit Racing site I also learned that they still have 496 long blocks making 575hp, with alloy heads. And I've seen 610hp/665tq combos elsewhere, that would do wonders for a 2500 Suburban LT...Or add boost to your 370hp version, for better efficiency climbing mtn. passes.

You tricky ol man! I was thinking LS5 and LS6 until i saw the engine cover and TBI... Tricky, lets see that throw down w mild mods. I know its very cost prohibitive

With the gen 5 and a tbi would a vortec head, intake swap and cam work with the stock tbi and make for a good tow rig? Would the tbi even run this setup? Not interested in high RPM just looking for a torque towing rig.

Id like to build an l21 swap heads, cam and intake plus do pistons with valve relief so you can run a monster cam. The l21 already has forged lowered just needs pistons to be beast. Push it to around 700hp na then add boost. Keep a 4l80 behind it and swap the converter. Should make lots of clouds on the street.

I was wondering if you could do a video on comparing 6.0ls to 454 na. I have seen the 4.8 vs the world video. I have a C10 and I'm trying to decide between the 454 or 6.0 I have both setting on engine stands. I have looked there's very little videos comparing bbc to ls. Keep up the good work the Engine Info is why I used to read the magazines.

I wonder what the best MPG of all these combo's would get ?

Why don't you do a dodge 318 and 360 shootout or big bang motors

Hey Richard! I have a Gen 5 454 with a Whipple supercharger on the factory TBI intake (Very weird setup that was apparently dealer installed on my 1995 suburban). Got the entire vehicle for $900 with intent to swap the engine over to my 72 Camaro. What do you think I should do with the engine? I want to make more power but the supercharger works with the stock TBI. Not sure if I'd make more power just putting an intake and carb on it, or keeping the supercharger.

Awesome video Richard. Question: the Weiand inlet manifold used on the Gen V, was it the street warrior part #8122 specifically for peanut port heads. Or was it a large oval port manifold?

Nice upgrade to the big block I'm doing something similar also with another 454 a gen 5 I'm installing a comp hydraulic roller Bootlegger cam with a set of early closed chamber oval Port heads that have been machine for the larger valves and better Springs to match the cam my plan down the road is to put it inside of my 78 Buick Regal with two turbos cruise around on the street daily driver as you seen with the other projects in my shop that I'm doing LOL I'll send you some pictures

Pick your part junkyards in California back in the 90s thru 2010s was very hard to find Chevy big blocks in anything! I remember the yards would have written on the windshield “pull BB engine” to be sold separately. That is if you could find them! But that has changed. I see gen V and gen Vi often now GMT400 pickups

The Gen 5 454 fuel pressure regulator on the tbi needs to be changed and adjusted, if there are AM 454 FI for the TBI change them, and port flow and valve job the gen 5 heads. You can always switch to a roller cam, solid roller tappet/lifters or even hydraulic tappets, roller rockers. Or change the stock heads to AM, or switch to TPI. Also if using the 1987-1995 ECM/PCM replace the eeprom with a superchip.

Nice truck / towing combo with that gen vi . any recommendations for getting more power out of the stock TPI with that cam/header combo ?

Was that the Weiand street warrior 8122 manifold for peanut port heads? have one on the shelf waiting to go on my 330hp marine 454, cant wait to get rid of the low rise iron piece

I would like to see the tbi 454 on a dyno. I have a 1995 3500 HD. 10 lug rollback tow truck with this engine. The 454 is very weak even when running empty. Really considering a carb and intake maybe same small cam you ran on this Gen 5 combo

I was really wanting to put the 2015 or so Buick regal 4 popper turbo in my 1995 Saturn SL2. 259 HP 295 TQ ecotech, can always up the boost a little bit, has terrific torque and decent power for it's size. My suspension is already upgraded and lowered and wanted to also add a set of RPF1 Enkei's which will save me another 4 lbs a wheel also, would be very quick with that plastic body and I got a Seibon carbon fiber hood on it too. Maybe some carbon fiber seats as well? Buick is a great car, love your show man!!!

any chance you can find and run a Mark IV and see how much power you can get out of it with flat tops?

Would love to see a gen vi with cam and torqstorm. Been thinking about that combo for my 58 c60

I NEVER comment. But these big block junkyard videos are CRACK to me! I want/need more! Also have you done the Big Bang yet on the stock bottom end gen 6 yet!? I know in another video you had said it was in line but that was some time ago. Love your videos. From one Richard to another, thanks!

So the first comparison is really the same block with an updated head/cam combo. Are there any differences in short block between the two?

I have a 89 crew cab one tow chevy. Planning on installing a gear venders and doing a cam and maybe even a gen6 head swap. What would be a too low of a cruising rpm with 12k lb trailer behind. I’d love to see 2200 rpm at cruise

Love the 454ss trucks from the 90s

I started out with factory TBI & computer years ago before aftermarket tbi injection kits were economical. Ported factory tbi, thinner blades, higher fuel regulator spring, 454ss injectors on an RPM intake with a tbi adapter, Patriot heads, and an XE268 cam, which was about the most duration we could tune the factory computer (burning a chip). It would have been way cheaper and much less limited if they offered Fitech or sniper kits back then. Needless to say I went with a carburetor after the freshen up! Great videos BTW!

Two possibly non-related tests for you to consider, Richard: first: is it the 2 barrel carb or the manifold that costs horsepower? Pop a 2bbl on a good dual plane and see what happens. Second: how much do carbs actually flow? Is a 750 a 750, is a 600 a 600? How does a 500 CFM 2bbl compare to a 600 4bbl under the same condition on a flow bench? How does this all relate to power?

I’d like to see a video on the L21 with the factory injection in place, maybe a guy wants to keep fuel injection but make a little more power without changing up to much? Edelbrock heads? Cam? Intake porting? Or?

We need that Big Bang gen6 bbc I got a sbe gen 6 454 and 107mm promod turbo on the shelf !

Right on

I know some have mentioned it in reference to the 8.1L I was wondering if you have seen anything notable as far as aftermarket parts sine the new aftermarket 8.1L out now. How would it hold up against a 454 or a LS small block?.... 8.1L boosted to blow its guts out would be something I'm sure no one would want to see. Lol

Curious what your final timing came out to on the gen 6 with stock cam for optimal performance

It would be interesting to see what a Low lift high Duration cam's results look like then compare another cam (or 2) that have the same Duration, Same LSA but highter lift on a stock style cam (not a radical ramp and a flat peak).. I havea 96 Viper with a factory cam (107 LSA I believe) and thus alot of overlap....I am looking into changing the LSA to 115 and running more duration so as to keep the stock sounding idle.

@Richard Holdener Will a Gen 5 flywheel work on a Gen 6? The factory gen6 has a very narrow contact for a clutch contact. The gen5 has a wide machined surface. Thanks for your insight.

you have to do a 4.2l trailblazer motor bigbang

Hey Richard love the content!! You've made me decide to run the 276 hr cam in l29 equipped chapparel boat!! Could u please tell me the part numbers for the beehive springs and keepers and rotator eliminator please

Hey sir I appreciate your channel…I have a 2000 gen6 454. I want to put on cam heads and headers, stock intake. Can you suggest a cam and head combo for me? I do tow. Tia

Does a conventional bbc oval port intake like an Edelbrock Performer, fit right onto the gen 6?

What do you consider a good price for a junkyard gen 454. Considering replacing my 396 I. My SS 396 68 Impala with either a 454 or 502. Trying to keep it looking stock but looking for at least another 150 hp over the 396. Or would you just build the 396 to get more power.

I think u meant 381hp not 281hp for the gen 5 cam upgrade

Please do a 440 with Cam modern cylinder heads and decent compression

Richard. Question. I have a Gen V 454 and going to use 336781 heads. Should I use a Gen 5 head gasket? I heard stories of even the head bolts not lining up. Can you clear this up? Thank you.

Intro music rocks!

How about plopping gen 6 heads on a gen 5, since that’s about the only low buck head upgrade. Keep up the good work! 🍻

What is the Biggest 1 BBL carb you could modify, and how big of a motor could that run on?

I know this is an older video but could you please explain the process and requirements to make more power with the gen 5. I am getting so many conflicting results trying to research how to cam swap and what's compatible and how to swap gen 6 heads on the gen v and stuff like that. How much lift can I use, can i use hydraulic roller tappets? What heads can I use?

Run the TBI 454 ON THE DYNO, NO 4 BBL AND NO HEADERS

I got an idea for a killer test. Why not run that 372 with a bunch of old intakes? We all have old intake manifolds hanging around. I personally have a had a Torker and I have a c3bx.

Richard please tell us what optimum timing is on gen 6 🙏 i hear anywere from 8 intial 29 total to 14 intial 36 total????. This is of courses with carb hei distributor cam headers Thanks justin

Richard,got a question. Does OBD1 recognize compression? Thinking about putting a set of Edlebrock TBI heads with 110cc combustion chamber heads. Will this mess with the ECM?

What is the intake manifold to carb swap a gen 5 motor?

I'm building a gen 5 454 I'm installing tg e gen 6 heads. WHAT'S THE BEST CAM 276 or 282 xtream energy cams. I'll be upgrading my springs as well ..

Have you considered using OBS to record your webcam so you can get rid of the watermark from the other software?

Richard, I wonder how close the gen 5 would be to the gen 6 if you used the same cam that was in the gen 6 in the gen 5. The gen 6 had 204/209 duration at .050 and .480/.483 lift with 118 LSA compared to 193/203 duration with .398/.430 lift and 112 LSA on the gen 5. There is about a 35 horse difference, I would guess the compression difference is worth about 20 horse. I would think the peak hp was moved up in the rpm's with the gen 6 cam. That makes me curious on what that cam would do in a gen 5. If you move the gen 5 torque numbers up 300 rpm witch would match where the gen 6 makes peak hp. If my guestinations are correct, that would add about 20 horse. So wherein lies the gains of the gen 6 over the gen 5? Something tells me the head flow doesn't have much to do with it. Stein Weiss's web page would suggest that further too. 🤔 I wish I had a dyno.

What roller rockers clear those valve covers

I was just looking at a 1999 chevy truck with a 454.

We had a gen4 454 in a motorhome and I Know a 383 could easily out power that engine, that's my guess, gen 4 366 has a forged crank and nice rods, and oval port heads, add that to your 454 to build a 427 with

Does the gen 6 have bigger ports (better heads) ? And is the gen 6 the one with tall deck .? What years were the gen 6 available?. Basically they both need more cubes and more compression and better heads and better cam . Possibly forged internals. Etc

Richard can I run a XR271HR-12 In a stock bottom end gen 6 454

I rescued a gen 4 out of the wrecking yard. Rebuilt it. Which i never messed with it. Nobody wants it.

has anyone developed a cam lobe where the Ramp up to the peak (from the base) was different than the ramp down to the base circle?

Sweet, I have a 6th gen laying around.

Can you do one with a gen 4 tryna see what I can do for mine

I'd love to see this done with the Holley efi sniper. Really cheap fuel injection that will support 650hp. IDK it's a thought

When adding a higher lift cam (.500+ lift) to the gen 5, do you run into valve guide to spring retainer clearance issues?

Anyone know where I can find similar headers to the ones he use?

What are the years for the generations?

HELP I need to find an Edelbrock 79-555 aluminun big block chevy head !

I have one out of a suburban What oil pan would I need to drop a one of these gen 6 in a 65 Chevelle? any help would be great thanks

What about the edelbrock top end kit for the gen 5 ?

what about TBI from a gen5 454 on a olds 455, stock RV cam , we have a GMC motor home, not looking for more power or RPM just easy starts and reliability, do not have room for a taller intake.

Hey rich whats a good combo for a stock gen 6 looking for cam intake ,carb ,values springs ect using stock heads

@9:32 - I think that's suppose to be 381hp.

I love that you run this old junk on the Dyno for cheapasses like me. I have both of these engines in my stable.

Are you running the stock lifters, push rods, rockers and valve springs with the upgraded cams?

what is the expected hp and tq gain in a gen 6 with a ZZ502 cam, standard duel plane intake?

BBC for the win on the streets anyday... Seen a 496 stroker knock the dust off a ls7 corvette in "Mexico" this past weekend👀👀👀 Gaaaaap🗣️

How would they compare to a 8.1L?

when we gonna see junk yard gen 6 454 with stock efi /intake with new more better cam, mybe heads too all with stock efi and intake.? seems like a easy way to make over 400 hp and lots of TQ . we must know! lol

So what gasket do I use to put the gen 6 head on my gen 5 tbi

Would you entertain the idea of using 1.8 rockers on a gen 5 454 that has a stock or very mild cam?

How do you tell the difference between a gen 5 and a gen 6 thanks Rich

Wondering what intake gasket you used on the gen 6

Did the vlv train stay stock on the gen 6

What’s the limit on these blocks as far as boring? Max bore/wall thickness?

I doubt it will ever happen, but would like to see what just swapping the Gen VI heads on a Gen V would do in terms of gains. I am about to do just that. I have a 3k mile Gen V that I paid next to nothing for. And a set of Gen VI heads I pulled off of a locked up engine in the local junk yard. I will be upgrading the cam at the same time. Most likely something in between the Comp 256 and 276 that you ran in both engines. Will be topping it with a used Edelbrock performer intake and a 750 cfm carburetor. Thinking 400 HP and 500 TQ isn't too unrealistic? I know I could buy "better" heads and a hyd roller, but I currently only have about $650 in the engine, Gen VI heads, and used intake manifold. Trying for a true budget build for around $1000-$1200 total invested.
