Crossfire to Carb

I searched here and google a million times but can't find the info I need. First off I own a 1982 C3 and before anyone says I am tearing the car up by taking it off I am not removing the ECM or cutting the harness I would just like a carb setup. Anyways I can't find out what parts I need...I just want to make sure I get the right parts with the right clearance thats all...If anyone can please help me out that'd be great...I know I need these parts..Intake,carb,fuel pressure regulator,Distributor,700R4 Torque Converter Lock-up kick if theres anything else please feel free to tell me.

Thanks,

Brandon

Morning; I know someone that wants to do the same thing to an old C-4. As far as I can tell he is even asking the same questions. I will be watching this thread and will advise him to pay attention to it as well. Good Luck

Yours might work.

All of the above is stock Corvette. You could go aftermarket for all of it, but aftermarket goodies will cost you more.

FWIW: You will want to hang on to everything you remove.

Heres what you need

please note the carb and intake is merely a suggestion and not the only one that will work

Edelbrock Performer intake
Edelbrock 1406 Performer carb
Mallorey 4309 Fuel pressure regulator with return
Spectre Fuel pressure guage ($15 most autozones screws into regulator)
return spring
return spring bracket
a drop base air cleaner

some hose for vacuum lines and fuel line adapters so that you can run the stock lines into the mallory regulator

Any Hei vacuum advance distributer
(autozone stocks an Accell unit that is billit aluminum for $119)

And thats pretty much it minus a few hose clamps

with the above carb 5.5 psi or slightly below is the ticket

let me know if you have any questions about install

Sometimes you have to hang out and wait for the guys that have knowledge in the area you are asking questions. Seems like you have some good info now. Good luck with the swap.

One last thing, the reason I said the Mallory 4309 regulator is that it has a return and will send gas back to the tank, if you use a regulator without a return it will burn up your electric pump

No you won't need a converter at the most you will need a painless wiring lock up kit if you remove your computer.

When you say remove you mean just unplugging? right? I don't want to cut the harness or rip out the ECM.. and which kit should I get because there are a million of them now sure which would suit my needs.. Thanks again all this info is giving me alot less of a head ache lol

Could I use the summit carb and intake combo? Are these any good? the combo runs around 400 bucks so price wise it's perfect for right now
