I have a car street car that makes over 700rwtq with a 3.31 rear gear in it. My problem is it will break loose under throttle at 80mph. Your thoughts on a 3.08 or 2.73 gear swap.
331 dart, Dart pro1 heads, Hellion 76mm turbo.
i would look into tires or your rearend setup( the taller gear sounds good, but once those gears break the tires loose they won't stop spinning)
gear selection should be RPM when trapping or what RPM you what to cruize around at
hope this helps (nice horse power #'s)
