Guess ET for 318 ? With slicks ???

With 2.94s and 28" slicks - 15.30s
With 4.56s and 28" slicks - 14.00s

Calculators say about 260 crankshaft hp and potential of mid to high 13s as it sits. But like Longgone said... IMO it's a mismatch from the carb to the rear tires but those are fun to play with and see what you can do.
