Guess ET for 318 ? With slicks ???
I ran 4.56s with 26 inch tires In vegas,had to shift at 6,400 to go tru the traps at 6,800 barely on the limiter.Car is a light slant six car and went 11.97 at 109. all motor.I will run 28 inch tires next time at the 1/4 to get the rpms down.Going for the national record of 11.88.I would think your car would like 4.30s,dont think you will like the highway gears.
