get me in the 11's

What block do you have, 340-360?

Put a set of good decent bowl cleaned up Ede's, 11:1 compression, solid cam in the 250 @ .050 area with about 550 lift, victor intake with 1" 4 hole spacer, ignition, headers.

275/60/15 MT's or equivalent

Put a set of Cal tracks/ranchos on it if you don't have SS springs already. SS springs work, not my favorite. Look over at moparts for member sloan. They have a 68 Cuda that is pretty stout. Runs mid 10's in good air. Had SS springs on it and swapped on Cal tracks and it was night and day difference

Should be enough to get into the low-mid 11's. 11.30's at 3400 needs about 435 flywheel hp and 380 at the wheels
