T-56 viper box behind 545 cobra

[Double Venom]

For what it is worth department, I ran all T-56's in all DoubleVenom's (Viper powered Cobras for the newer guys) the Double Venom II was rated at well over 700 HP with well over 660 lbs of torque. Not that you don't need to follow any other posts, but pay particular attention to post #1. 1st and 2nd are WEAk, the main outboard spline may give you problems and if you do any hard shifting (Drags), you may end up ugrading the shift forks.

Unless you like to pull "wheelies" from a stop sign or redlight, first gear is useless, second not much better. That is why the Stock Viper with a T-56 will come with a "skip shift- which most guys including the Viper guys will disconnect.

For our purposes I like the 3:55 gear for all around use. When my family gave away the first DV at the third Spring Fling the car with street tires and low (for a Viper) HP was turning 11.00 flat at the Drags and broke records at Run N Gun.

I only went through one T-56 when the syncros started to go bad.

Double Venom Ed I was there for the fun year at R&G. The only car to run wheelie bars. Or you where trying to adjust the back bumper. If I recall you did wear out that trans at R&G for the 1/4 mile. I did like that car with a 488 cube motor. I just could not get over the strange exhaust tone the car made. Rick L. Ps didn't you bend the wheelie bar at R&G?

Powershift1038 Yes there are guys running stock t-56 trans with 800 HP turbo motors. Those trans missions do last than long. If you blue print the gear clusters, and have the end play tight they will last for awhile. The gears are not made of 9130 steel and they are not straight gears in the cobras. The viper trans had better parts inside because of the Torque rating on the 488 motor. It's not about HP, It's about the torque load that the drivetrain has to with stand. Add soft tires like slicks and the breakage increases twice as fast. A trans and 2,400.00 will give you a bullet proof box with a 800-900HP and 1000ft of torque rating. Side note, couple of weeks ago at E-town, a 331 mustang with single turbo, blew apart his T-56. He was in the 700 HPrange with 10" slicks. OIled the track down and junk all over. Something to think about. Hope you guys are running safety blankets for the trans. Just a Thought. Rick L.
