Alright so my father and I have rebuilt a few transmissions over the years (including 6 speeds). Well we thought it would be cool to put a 6 speed I have layin around behind his hemi in the challenger. Anyways its a big hp hemi, its a show car, doesn't see the strip but he loves to take it out cruising and here and there sometimes. What do we need as far as aftermarket parts in this tremec to make it last behind a 600hp hemi? Thanks in advance guys... For those of you interested in what the car looks like here it is.

Flywheel hp, like all those old cars were rated, right?
Why wouldn't a T56 hold up to that? Most hold up just fine to h/c cars spraying 150hp shots. So that's 600hp, for the most part. Bolt it up!

And that's rwhp, not fwhp.

...well its a built motor... but you make a valid point, maybe we'll just throw in some steel shift forks and stuff and call it a day

My stock T56 is surviving everything Ive threw at it so far.

For my application I wanted to ensure I wouldn't have to rebuild the T-56 again, so here's what I did.

-Viper OPS conversion
-Input and output shafts cryo treated
-Steel shift fork
-Billet Slider Keys
-Textralia OZ700SB

With those tires on the car you'll never hook it hard enough to hurt these trannys,don't
sweat it.
