What kind of cam is that? I run stage VI heads and have a Doug Herbert solid roller that 272-275 @50 and 620 lift. very similar setup as yours. What size converter is in it? mines 3800 lbs and runs 10.50's - 10.60 on the motor. Very sweet. I also run 3.91 gears with a 28" tire. I know on my setup it doesnt like high revs, if I shift it between 6300 and 6800 it runs exactly the same.
