My Barracuda 493 ci LD stroker 12.8 comp. SR MW heads ported by Dwayne Porter 337 @ .650, Wilson ported 400-3 intake, 1050 Dominator on E-85, custom 2 1/8" into 2" headers, 3.5" collectors. 8" convertor @ 5500 rpm, 3 peed torqueflite stock ratios. 4.3 gear. 2835 #s with me in it. 14x32 slicks.

Has run a best of 9.08 146mph.

Currently run a solid flat tappet cam .640 @ 276 dur.

Here's the questions; if I change to a roller what cam would you suggest?
Can I expect an improvement? How much?

Thanks, Don
