I'm running a 4.56 rear gear now with a 32.6" tire (next tire will be a 33), I'm building a new 400 for it and thinking that the 2.48 might be a bit too violent behind a 615ci BBC off the line, motor should be in that 1200hp 900trq give or take range, est shift point 7800, but until its on the dyno these are all just numbers off of past builds the shop has done.
Anyway wondering if I should do a 2.10 1st gear instead.

71 Dragtruck Just had TransKing freshen my 400 and added 300M input & main shafts ; clutch hub and a 2.22 1st gear from Coan. If you have any questions let me know maybe can help out.
