Does my 451 have to small of a cam?

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"?
