So I picked up this 87 iroc stick for 700 bucks on Sunday. It had been sitting for 2 years on a trailer with a blown 383, I got the complete blown motor and a 80-85 350 with a cam and flat top pistons. I also got a newish clutch. I think I'm going to just put a stock 305 TPI in and then port it and put some rocker arms on later.
