Feel free to ask anything. Any questions, more pictures, advice, post it below!

Thanks for this. Corvette owners LOVE talking outta their asses on forums, good information is so hard to come by.

All that you did to your corvette also can be applied to many other chevy engines all your information is spot on for the list of parts needed. It's probably way more fun to drive now and dependable and can easily handle those long daily commutes to and from work. I know for a fact. I did this to a 99 vortec 350 and dropped it in my 86 gbody and I commute over 50 miles a day for over a year now with no issues. Great source of information for anyone thinking of doing this to their ride

I have been wondering how to go about doing this with my C4, there is just so much crap on the motor , every motor I have ever rebuilt had a carb on it and when I started on this one I was blown away by how much smog and bs is on the engine, ty so much for this video it sure helps a lot.

Thanks for the info hope it's still running good !

very nice truly enjoyed

Plan on switching my Camaros TPI to carb! Thanks man!

Keep up the content

Great video. Been thinking about a t bucket and the wiring nightmare. Thanks man !

Great video and information

I'm using an l98 in the entire running gear including wheels suspension and Flowmasters from a 90 Corvette into my project truck. The intent was to run fully computerized injection. So it has a ECM that's been modified to delete all of the things like anti-theft etcetera. My plan is to switch to carburetion so I can get this forever project on the road. So it seems logical that all I have to do is get a distributor and a fuel regulator. Have the exact same manifold that you do and my intent was to run an avs2 so there's that coincidence. I was worried about the original electric tank pump but it seems like this is the singular most useful thing at about your video. Well done lots of still pictures and not a lot of wasted time talking I appreciate it

Good info. I am thinking of pulling the L98 and 700R4 from my 89 Vette to put into my 80 Trans Am. A carb conversion would be a must.

Awesome video and great content. I'm planning on putting a dual carb tunnel ram set up on my ' 90 Convertible . I have the tunnel ram and the HEI distributor. . And honestly, i don't care what the haters have to say about it . I can hear the haters crying about it now . A friend of mine , put a dual carb tunnel ram set up on his C4 , without any issues. I subscribed after watching this video .

I picked up a l98 out of a rear ended corvette. The engine was already out the car when I purchased it and wasn’t able to hear it run. But for $500 dollars I rolled the dice. Got it home slapped on a high rise intake, 650 carb and a HEI distributor and it fired right up. Awesome throttle response. And I will never ever ever have to worry about injectors and all the unnecessary wires. I’m stuffing it in a 82 s10 I picked up for $500 bucks as well😂🤘🏼

Best video I could find thanks only difference is I have a Holley carb gonna install this weekend

I appreciate this video! Seems like a great solution to get some more top end from these l98’s. Probably not a bad idea to throw a cam in it as well

Great video. I just did this same swap on a 1990 suburban 350 efi for all the same reasons you mentioned I used pretty much the same items you did. There were some things different however. I couldn't figure out how to get the fuel pump to keep pumping after the initial startup. So I simply bypassed the factory fuel pump regulator on the firewall. There was a factory installed wire for this already there so I hooked it up to the tach side of the HEI.

the only problem they always face on a C4 carb swap is the hood there simply isnt enough clearance for the aircleaner most guys run the buick snorkle to remote filter but theres barely any room

I just got a carb and intake to convert my crossfire c4 tonight lmao. This was a very helpful video thank you sm

I did a1991 Corvette. Easy Peasy. I bought it for $950. New tires & transmission. Beautiful black interior. The previous owner had it in four shops. They couldn't fix it. Smoked, fouled out the spark plugs drank gas...... He put everything new in it. Everything.

great video just found it want to do mine now ....

Love this, I mean really fucking love this. Nice job

Hello and thanks for the time spent on video. I'm doing engine swap on my 86 vert. using a Blueprint 396 stroked sb350 (Engine dyno 508hp/ 525 torq) Can't wait to get it doneand driving. I am trying to figure out what to do with the injector harnesses, does anyone know if they can be "unplugged" anywhere? I've leaving the brain box in place. Thanks again!

Good call on getting rid of that money pit TPI. I don’t care for them because they run out of breath at 4000 rpm and chip burning is a lost art in 2023. Carb swap makes better sense if you actually plan on driving the car.

Yo perfect vid!!! Gonna convert my crossfire to carb.

Great Job Man!Doing this as we speak.What did you do with you heater hoses?

How do you like the edlebrock ?

Gonna carb an 87 L98 that came out of a corvette and gonna put in an 87 Monte Carlo.

Love the video! The only question I have is what the real power difference was in the end, did it pick up power or stay relatively the same?

Hey, im doing a similar swap. What did you do for the upper radiator hose. Do u know the part number? As well as temperature sensors for the fan switch. Thank you

Very informative. I like your take on how it's your car, and it's your money so it's your business. Lots of people out there do try to push you away from carburetors, and it's ashame. I still prefer a carb over EFI any day.

Thanks for the great video just wondering does the dashboard cluster still work after go to carburetor . Or do have to change the all the gauges

Which coolant hose did you install?

I love how much cleaner the engine bay looks.

What is your opinion on adding a Holley sniper system? 85 base model, pretty much bone stock

I’m having a hard time on my 88 l98 with aluminum heads(factory) the problem I’m running into is my 2 center bolts for my intake are at a slight angle. I know the Vortec heads have this issue as well now. Can I take the intake style for the Vortec and put it on my l98 without any troubles. It’s going on a 1984 Gmc. I have a old school pro comp high rise on it and want to go to a mid rise dual plane intake but I’m running into the boot angle problems. Any help would be awesome thanks.

Thanks bro my iroc keeps shutting off while revving but it can idle beautifully for hours but it acts up so carb it is

So you used a 2021 intake?

hey was wondering how to hook uo a manual oil gauge i think i got the coolant and volts understood just the oil need figured out in my head

Thanks for this great video!! Answers a lot of my questions and concerns.

I did a carb swap on my 84 vette. Ie cross fire. It was much better

Ty, son.

How about a lt-1 conversation? To get rid of the opti spark!

I read that these carbs have a fuel starvation issue in hard turns. Has it happened to you? 8128 is the part number for the dual feed fuel line to keep both bowls full during sharp turns.

I think i heard you say you used the restrictions on the back of the intake? Or did you just leave them open? Plus, there's a lot of haters on here. The vette im working on now caught on fire from leaky injectors. Never a fire for me with a carb. But most people are right on here... hook hose fom pcv valve to front of carb. 3/8 hose

I am in California and I need all the original TPI parts so it can pass smog someone did this to the Corvette I just got but it's missing stuff will still run but like a dog watching this hoping I can reverse everything lol

Mine is a 91 i would like to do it.

I have an 88 Camaro TPI. I pulled the 305 and I’m going to put a 350 carbed engine in. I left all wiring intact. What wires will I need other the coil from ignition? I want to use original oil psi gauge and temp gauge. After adjust TV cable. Will trans still shift normal? What other wiring do I need to do?

Just did this to my 86 iroc z that has a zz4 350 crate motor sat for 20 years the tpi was a headache to work on so i switched to a carb

Will it haul Butt now ?

What about coil /distributor wiring?

How did you get around the engine warn lamp triping with no EGR etc ? I'm right in the middle of comp engine rebuild on my 91 c4. I like the carb look and idea. Also did the mpg change much ? Thanks new subscriber

I’m currently swapping an 85 L98 into my 84. I’m gonna order the kit you ordered and an hei distributor. I need to know how to set the TV cable

How does the removal of the sensors you mentioned affect your gauge function on your dash? What about the OD engagement on your 4+3?

Did you ditch the ecm? I would like to keep cruise control. does your cruise still work?

Need to know if there is a regulator on the return fuel line? Thanks

Wondering what distributor you used? What wires you were able to eliminate and how

You're carb and intake kit numbers is the same as the thermostat. Could you fix that part number?

Love the carburetor, took the efi off my ls swap since it was the only way i could afford to run boost, pretty much all my projects have been carb ever since , great video man but how are the pipes already going out on you? Im running a cheaper ebay builder kit and its holding up my heavy ass gt45 turbo just fine its been supporting the weight for the past year now without issue but i agree on the carb swap people really trash carburetors but they really are easier to work on

Hey what's the part number for that upper radiator hose? I could see it on the actual hose, but it was not very clear. Thanks.

I also have an 86 Manual trans that was my grandfathers. unfortunately the motor has expired and do not wanna reinstall all the tpi stuff like you. I have a 350 with aluminum heads being built and am switching to a carb everything you posted is what I’ve also seen on some forums about using stock pump and a regulator and hei distributor. My question is what did you do with the wiring harness with everything that’s not being used anymore? Just cut it all out? Thanks for any help

I put a carburetor on it. Problem solved.

Hello from Romania 🇷🇴 This is my story, maybe you can help with more information about what i whant to do with my 1993 LT1 ! Long story short, i have a small colecțion of american cars, i love them ! I have a 1993 5.7 LT1 Camaro, a 1997 3.8 Camaro, a 2002 3.8 Pontiac Firebird, and a 2001 Cadillac Deville DTS 4.6 V8, the one with night vision and head up display! If could i would get them all ! 😅 Now, i whant to carb swap my 1993 LT1 Camaro because of the Optispark. I allready have the motor out, transmission, i wil get the rear end out when the engine will be done. I got it out because i will swap it on the 3.8, because that one has romanian papers and can be driven. So, i did my research about this swap on the internet but some swaps get to 4000$, thats alot in romanian money plus shipping. This is a budget build, and what i whant to do with this engine is like this ! Gm performance carbureted intake GMP intake, that has a long part number, a hei distribuitor, wires and spark plugs. And some ground wires dont know how many yet, but thats why i am writing heare. Then i need a water pump, radiator, starter, alternator. Other then that ? I have found what manual valve body i need for the transmission, i think it's a 700r, it has that tv cable and 16 bolt patern of the oil pan. Is a 650 cfm carb good as size ? What kind of carb ? Do i need a coil beside the hei distribuitor to start the car ? What fuel presure regulator should i use ? What aftermarket gauges i need to use for the spedometer, rpm, oil and water temperature ? If you can help me with other information about this swap that i whant to do i would apreciate ! If you have Facebook or Instagram we can speak there more easy ! If not its ok heare to ! GOD BLESS ✝️

Good stuff man!!! Does all of your gauges still work?

What distributor did you get? I have been looking on eBay and I don’t know if I should go with a cheap or expensive one

I just came across this post. I want to do the same thing because i want to run a turbo and don't think tpi ia the way to go.

What happens to the gauges when you go with a carburetor do they still act as normal?

Will this work with a 84 Vette Cross Fire

I want to do something similar with A Mitsubishi 4G63 Out of a lancer or eclipse or eagle talon. So I don't have to worry about computers,

Bro does this work on vortec motors please let me know I can’t find a lot of information on it

will this work on my 87? i heard holes dont line up? if you know otherwise please point me in a direction soooooo done with tpi

Did you cut off the fuel injector plugs or leave them? What changes if any to the computer?

This is a neat idea but I will never do this to my car. Why would I ever replaced tuned port injection with a carburetor?! I would probably understand why you would if your vette is cross fire injected but even then, cross fire injection was supposed to give better performance and be more economical than a regular carburetor.

I’m converting my 84 now, you didn’t have to run any power to the fuel pump? I’ve cycled the key on mine but it’s not ready to start yet and I hear the pump run for a couple seconds then it shuts off. I’m running an hei distributor also and I don’t understand how the pump will run without the stock distributor

What's the part number on your top rad hose

Anything done to the ecm like take it out or just leave it in.

I'm just curious was the motor bone-stock? Because your Dyno numbers don't add up there's no way you got that much horsepower out of a bone stock l98 and there's no way you had 150 horsepower with a carburetor intake and headers. So just curious what mods were done to the original motor before you got it and how big of a cam you put in when you swapped to the carburetor?

How much whp do you think you have? Looking at getting a C4

So you did not remove the ecm or wiring harness?

TPI had crummy higher-RPM power, yes?

That's not a kick down cable it's a TV cable that lets the transmission know when to shift. Without the throttle valve cable placed correctly you can burn up your transmission.

tpis intake /bbk throttle body for sale..lol

How easy was it to tune? Ive heard you need to be an expert and might take some days

Without cutting the hood, you're losing your cold air intake. But to each, their own.

💎💎💎💎💎💎💎💎💎💎💎

waterpump?

Unfortunate that the car only had 60k on it for this. On the bright side, this helps raise the value of nice TPI cars.

Corvette people like this choice of music? In their straw hats? Didn't think so.

why screw up a corvette like this

Not trying to be a hater. I am not like you. I am old. I love fuel injection vs carberators. I am old enough to be your grandpa. Carberators belong on the bottom of the ocean. Fuel injection on these old cars have fuel injection that is so far superior to any carberator.

That is stupid! 400+ hp with TPI is so easy, and you are losing all the mid-range torque as well!

wtf u do too your PCV bro?? lol thats not how those work, you need to get breathers.

Im thinking of swapping my LT1 to carb.

You HAVE to have a pcv valve installed. Just airing out wont do

I plan on picking up a 84 c4 vet and I want to convert to a carb and then go from there as far as upgrades is there a way we can stay in touch do you have a Facebook

compared to tpi thats 5 shades of ugly...
