452 heads on a 1965 Wedge ?

There's a guy over on The Hamb who runs on the street with 13.5:1 with iron heads on 93 octane. It's an Early Hemi, but he's got it done. I understand he drives it a LOT, too.

LOL...there are so many guys building higher than orthodox compression ratios pump gas engines it's not funny.

Then you have certain people who will argue to the death it can't be done because THEY can't do it. Sad really.
