Offenhuaser dual port intake and Holley 550 on 318

. On a scale of 1 to 10 you may get a mushy 4. Remember longer duration and higher lift is what gives you better compression and power. New lifters and timing set will give you a worry free motor you will be much happier with.

i agree that the cam will help. good advice, but i disagree, long duration cams do not give better compression
