Used to be...



Well... its not quite Speedtalk... but i'm thinking ov getting one ov these cams for my hotrod... which i fully intend on racing, and often. Does that count...???

Dont think i'm getting my question answered anyways.


Ov course it does.
As far as the question you asked that no one gave on the 8.5 ratio My guess is larger CC heads?
I know that in the years i have played with 340's some had taller deck hights and I have a set of J heads that are 74cc's those 2 alone would bump you way down in compression.
As I said I is a guess on my part that the OP had his piston way down as far as deck hight and not the .020 above like a perfect blue printed block would be and the CC of the heads were large as some run...........
