Go there I don't know what heads or cam are in it now, because a guy rebuilt it for me. I know the block was a 350ci built from 1988-1994. I have 3:73 gearing in the back. I have a b&m quicksilver shifter it is automatic but I hav the ratchet shifter so I can use it for manual shifting too. If you need the casting number for the heads where do I fond that number on the heads I have? The car is a 1985 cutlass supreme and I drive it maybe once or twice a week and I want a fast car so am looking for food hotsepower numbers. I am just curious what to do with the heads and cams I hope that helps. I'll check back later
