limited to 275hp Reply #15 – September 10, 2009, 08:25:08 PM Call Comp cams in Memphis, they will grind the best for you. GT 40 cast iron heads, and roller rockers and Edelbrock RPM or if you are going to run the revs up a bit a Torker II. should put you right in the 300 HP range with great reliablility. I have one thats going on 100,000 and no mechanical problems. Quote Selected
