Me and my son are trying to figure out what to do. I gave him my 1980 camaro after I had my Posi traction rear end with 3.08 gears installed on the 80. now I purchased a 1978 Camaro and it has Limited Slip. I am wanting my posi traction from his 80. He is trying to figure out what to install on his Camaro. He is going to have 330 horses moving his car, Mine will not be near his. I will be putting a new 350 engine, with a few mods, but nothing like his. What would you recommend for gears on his car, and whats better, Limited Slip, Or Posi traction? and what Gear Ratio would you recommend. Please let me know what you think.
