Hey all, first time poster here so bear with me

I have a 1991 Camaro RS, with a 3.1 V6 auto. The motor is running pretty rough, its got a 130,XXX on it, so im thinking it might be time for a new powerplant. My question is..... is it possilbe, and how much work is it to replace the 3.1 with a 305 or a 350 v8 and 5 speed manual?

Ok, newbie question also....would i have to buy a 305/350 from another camaro, or is a 350 a 350, no matter were it came from???

Thanks so much for any replies, im sure you guys cringe seeing newbies like me on here!

Welcome to the site.

I don't know what is involved in your possible swap, but I will comment on your car.

I have a 1990 Barretta Indy with the 3.1 in it. It's been a great car although it only has 30,00 miles on it. I've owned it since new and have had a couple of problems with it. My suggestion is to do the proper checks to see what is wrong with you engine. Compression check, possible leakage test if the compression test warrant it, electrical test to see if it needs....plugs, module, coil. wires, injectors (they had a lot of problems with them) or maybe the EGR (another problem with those engines. I think it's a good engine and has plenty of pep.

Changing an engine is a lot of work and/or expense. If you would rather have the V-8 then I can only say to seek professionals that had done these swaps. I am sure that you can find a message board that caters to the 90's Camaro and find someone that has done this swap.

I wish you a lot of luck in whatever you do with the car. After all, it is your car and I think everyone should make it what they want.
