I would run a 3.91 or 3.73 gear. I ran 4.30's in the cuda and changed to 3.91 and ran faster. The stroked small blocks have a ton of low end power and dont need the tall gear. The cudas best 60' was a 1.36 with a best of 9.98 @ 134. running the MT street radial. I wanted to try the 3.73 gear but didnt get a chance to. Theres no need to wind up that long arm small block if you dont need to. Trust me, you wont be sorry. For a street strip car stay with the 3.91 and 28" tire....Phill
