Has anyone gone from say a .509 hyd. to the .590? How much of a difference would there be given say a 10.5:1 440 fairly ported big valve 906 heads. 3800 pound b-body.
that is kind of the same situation i'm in,but mine is 542ci,915 heads ported,comp?509 hyd and going to a 590 solid,single plane intake and dominator. Oh ya and the best mine has run was 10.92@123 and trying to get to maybe 10.50
