JoeDust asked about fuel/tires. FuelSystem is a 10gal. Fuel cell with 1/2"steel line. The pump is an elec. High vol. With an ajustable regulator at the carb. The prev. Owner has it set at 6psi. The tires are street tires 265/50/15.....ScampTramp,He never took it to the track and the nimrod sold it to buy a 86 trans am. The rear susp. Is some kind of ajustable,I haven't figured it out yet? There is also something mounted up front for the fuel line called a "COOLCAN"?

It would help you alot if you ran a sticky tire, make sure the fuel system is keeping up, this is "vital", especially with BBs, make sure the pressure doesn't start falling off when you lay into it, especially in high gear.

You mentioned it felt like the brakes were applied, have you pushed the car on flat ground to check rolling resistance?

What kind of car is it?
