Almost 950ft/lb here. Only time it's broke has been when we took some teeth off the ring gear (Dana 60). Broke the O/P shaft and rolled the sprag. It's got a lot of aftermarket stuff inside, nothing lightened just all the H/D steel stuff you can get and has worked great, although now I've probably jinxed it

Who knows what used parts have been through before the average tranny builder reuses them I like new good race parts from Dave Smith in all of my all out race trannys that he builds for me

I'm at about 1100 hp w/ a 727 in a 3900 lb car. 8.90s at 150 mph. Billet steel drum, TA transbrake (no LBA), A&A 5 pinion planetary, bolt in sprag, cast deep pan, your normal good clutches, etc. and that's it. The rest is stock stuff. Knock on wood, it's been good so far.

That's half the battle building a good trans - knowing what's good and what's not. Guys can buy the "build a trans" book but that only gets it assembled. Using parts on the verge of failure only gets you limited life - guys that know what to look for don't use those parts. Starting with a good core takes a lot of risk out of the build.
Exactly. There is a difference between a builder and aN assembler. This stuff is old. Some wear in the sealing areas, where rotating parts ride, etc. Most of the time the stuff us pretty good, but not always. Mine needed a reaction shaft support this freshen. Not broke, just worn in the sealing ring land. Doug

Back in the 60s early 70s most all funny cars used TFs, how much HP did a blown nitro Hemi make then? They called them torchflites back then too lol. I'd say about 2000hp back then
