I have run 3:23 and 3:72?and 4:10. 4:10 is a bit much, but the best gear for me. 3:72 or 3:91 for street car leaning towards 3:7, I run yukon gear 4:10’s IIRC. but there is only a couple of manufacturers.

best of 11.24 at 119 mph 1.60 60’. 68 340 S Barracuda Fastback F.A.S.T [IMG]http://i67.tinypic.com/2mnnnnt.jpg[/IMG]
