I currently run 3.91. I also have a 4.30 pumpkin. If your big block is putting out good tourqe you do not need a lot of gear. With a good tourqe converter 2800 or so, 2.94 and or 3.23 are great gears. I ran a 14.65 @ 96mph with 2.94, 11 inch converter. The 3.91 gears just get me down the track quicker 14.018 @ 95mph.





You are giving up 6 tenths in the 1/4 mile so I would say you do need the gear for drag racing in that combo. If you dont care about your 1/4 mile et then yes the gear dont matter. I do agree some bigblocks make enough torque that you wont need as much gear as a combo with less torque. Ron
