Recommended Info:

Gearing and Tires: 3.42 w/29" tall tires
Headers: 1 3/4" Headers
3" Exhaust w/H pipe
Reworked Stock HEI distributor totaled at 34 degrees
A street/strip 10" 2200/2500 converter.
This is a fairly mild working daily driver combination, making approx. 425 hp, in a car that can run 12.40's with stock type suspension, a/c & weighing 3800 lbs.
***This combination can run faster changing the cam(at no extra charge) to a Comp Cams XE 274H, this will increase horsepower to approximately 450/475 hp, but will require changing to a 3000 converter and have a rougher idle.***
This change should put the car right at 11.95's to 12 flats!!!
