Sixpack on a 318 engine ?

My opinion only:
A few cubes difference between a Ford 302, Mopar 318, and a 327 chevy, doesn't mean much. The difference is, there were real performance versions of 289/302 Fords, and REAL performance versions of the 327. That is not true of the 318, and it's reputation suffers.
Put equivalent hi performance parts comparable to the 365/375hp versions of the 327, you should get comparable results. Trouble is.... Mopar never did.

The 365/375 horse 327 had a cam in this range. Speed Pro still sells it. Put it in your 318 along with a nice intake and carb and some headers and see where you go. I bet that 327 had 10/1 compression at least which the 318 lacked. A 300° cam is pretty nasty especially in a small cube engine.

The Chevy guys say it comes on strong at 3500 to redline. (no idea what that is but guessing 5500+)
