Eastern Panhandle Camaro Assoc.

My name is Chris, I have a 91 Camaro RS. It's not much now, but it does run. I'm looking for some tech info if anyone can help, electrical issues. Currently has a V-6 in it. I'm building a modifyed 350. How do I upgrade the computer module to accomadate a V-8? Other than that I've been working on suspension upgrades, interior, and exhaust. I haven't done anything body wise. I guess I didn't want to draw attention to my ride until it was ready to be shown off.

Hey Chris and welcome.

From what I have heard, you cannot modify a V6 computer for a V8. Only thing you can do is to uy a used comp off of ebay or somehwere. Of course..you could always get rid of the computer and just go with a carburated set-up..

welcome to the group man i have a 91 rs 2 but i have the v8. is the 350 fuel injected or carbed? if its carbed u dont gatta worry bout the computer only the vats system thats the chip on your key. check out ebay lots of good parts on there 4 good prices

you could get a one out of a totaled one in a junkyard but ur best bet gonna be ebay most likely, is it a LT! or LS1 or ?

Hey thanks Travis. I do plan on making it carburated, duel carb actually, polished elderbrock air-gap intake and twin elderbrock 500 cfm carbs. I know I have to bypass around the computer eliminating the fuel injection, but not sure how to keep the check engine lights and other sensors from bogging up the car.

you can put in a computer from a carbed camaro

psss.. sensors..you don't need sensors... haha.. seriously though try to find a comp out of a junked carbed 'Maro... even then you will have to have it tweaked at a shop that has computer tuning capabilities

Thanks for the info guys. Little more info. I can't call the engine LT or LS. I took the block out of a 70 camaro cause the cylinder walls are thicker from 74 and below. Bored it out .60 over, reason for the thicker walls so it don't have as much overheating problems. 3.75 forged crank, 6.00" manley rods, 2.02 intake 1.88 exhaust valves, 236/246 @.50 duration comp cam with .586 lift, and I listed before elderbock 500 carbs. Pistons are Keith Black 9.5:1 simply because I plan on putting a procharger supercharger on it.

get in touch with dragcamz28... he has a 3rd gen that as a befed up 350 in it.. see what kind of a computer set-up he is running.. he can prolly help you more than most of us..

there goes your gas mileage

Welcome, it was nice to meet you at the show the other day. Glad you decided to join.

There is alot of tech articles on thirdgen.org about v6 to v8 swaps and EFI to carb swaps.

Chris,

Welcome to the club! (I'm partial to Rally Sports.)

welcome man....its gonna be cool to not be the only guy with a strange swap....i should have read this before i replied to your pm. Can you make it to the show this friday or sunday? If so ill tell you everything i know about switching from fuel injection to carburators.

I'm planning on being there Sunday. It'll be later, around 12:30 or 1:00.

Alright....well youll have to meet up with us when you get there. Ill show you what i did, but im sure youll want to do it a little different becuase i got rid of my heat and stuff too. But ill show you how to do yours the way you want it. And you wont need to get a new harness if your going to be using carbs.
