If I remember right, the 365 solid lifter 2.02 head motor had 11 or 11 1/4 to one.
Put a modern solid cam in, some econo w2s on it, 10 to 1 pistons, airgap intake with a 750 dp, headers in/on your 318, and hang on. 400+hp to thrash 327s (and 350s) with.
Edit: the solid cam 327s redlined at 6500, would go past that. I spun my hydro cammed 350 (370hp version) to 7500, cause it would.
It would have been quite a bit faster if I had shifted at 6500. DOH!
