Help with rear end gearing please.

"Scamp? What engine? Drag racing or street use? Fuel economy or acceleration? 4 speed or automatic? We'll get you the right gear!!!"

Correct it is a 1972 Plymouth scamp, engine is a 318 built by BJR 430hp/430tq, I plan to do car shows, drag runs, and cruises on the weekend with the wife. Acceleration basically, won't be driven alot, and it is a 727 auto. Tires will be 325/60R15 drag radials..
