Ok having a huge dilemma, currently in the process of building my 347 stroker, for my 89 stang vert, should be putting down somewhere in the 400HPs range, i know that everyone says that the TKO 600 w/ 600 ft lbs spec is what to go with, and a lot of ppl like the T-56 spec 450 ft lbs not the viper model, also, i am thinking about a turbo or s/c setup later, i can get the TKO 600 w/ BH, speedo cable, and 31 spline yoke for round $2000, i can get the T-56 w/ BH and Yoke for round $2040 then have to get the DS shortened and balanced, but am going to have a custom AL DS made anyway, so here is the dilemma buy the TKO 600 for round $2000 or the T-56 for $2040, i know the 6th gear would be sweet for HWY use and the gear ratio is kinda like having the TKO 600 RR with the TKO 600 5th gear OD so kinda get two-n-one for a lil more money, does anyone or has anyone put more than 450ft-lbs TQ through their T-56, also thinking about the 3.73s or 4.10s and still keeping some gas mileage, any suggestions or thoughts would help, thanks

I vote T-56, but just cause having a 6 speed would be SWEET!

really plus and minus for both, niether would be bad.

you seen these guys?

yeah i am leaning towards a 6 speed, and yes i have seen D&D performance, their prices are good but i have called them many of times just to see what all it takes to do the conversion and they are jerks on the phone and wont give up any details, they want your money for sure, i can't blame them though, they are charging like $499 for a custom AL DS i can get from my guys fro $275 so total cost for my T-56 would be about 2275 instead of 2699 + 150$ shipping, anyone put more than 500HP Through thier T-56???

I would LOVE to put a T56 into my car, just to say I have a 6 speed.. lol

then i would also run some 4.10's in my rear... would make up alot for the losses due to the high gear ratio

If theyre the same as they were a few years ago, the T-56 can handle more than its adverstised. How much more Im not sure, But Id still go with the 6spd, first off youll have better highway drivability, not to mention there'll be less wear on the motor cuz its nto spinning at high r's all the time. But if youre really gonna turbo your ride, then the T-56 will prolly take a dump once you put some serious power to it, that would be an expensive trans to blow.

Save up and go Viper spec T56. Best of both worlds.......
