had 4.10's in it and ran MT ET Street DOT bias out back and ET Front on skinnies at the other end.
not sure how much track time you intend on, or what the reasoning is for drag radial, but, I've found dr's to be a very frustrating experience with a 5spd and basic
suspension. Best on dr's, 1.82 (walking the clutch out and the gas down in a tightly orchestrated dance... not easily repeatable/consistent) best on bias plys 1.64, drop the clutch at 5500rpm and let it eat.
If the dr's are for track only, and you are not going to an adjustable clutch, engine management system and sophisticated
suspension, forget the dr and go bias.
