Oldskool... ATi is definitely one of the best, for Pontiacs , anyway... Ive heard alot of good about PTC, as well. But, i think ATi nailed my converter dead on, for the cam and the rest of the parts that i have... I'd have to do the math, but i trap at 6300 with 4.56 gear , 94'' radial, 116 mph, weighing right at 3500lbs. My car seems to pull pretty good, considering i'm running a 'small' cam(251/256*). and shifting about 5700 or so. This season, im stepping up to a 266/272, and most likely will want to loosen converter another 400-600, possibly. However, im gonna try it the way it is, first, with my lightened 350 trans, and some weight moved around, to the trunk, and see what i get. The new cam will move my power band up some, and will probably be shifting 6000-6200, most likely. Since my heads and intake havent really been worked over, thats probably about all the rpm it will be good for...but hoping that i can pick up another 200-300 at the traps, but may have to go to the 92'' radial, to accomplish that, unless the new cam gives me some HP, and wants to pull up better, in high gear.
