His profile says he has the R154, so I'm going to run with that.
A few of the big number guys have destroyed trannies, Will Neely is reputed to have claimed he could destroy one on demand with 733hp.
Seems like the guys under 700 have been mostly ok with them, though.

That's alot of freakin hp! We're talking NASCAR hp almost.
I think at that point I'd look at doing an M22 muncie conversion, w/custom gear ratio's. I don't think many other tranny's would hold up for any amount of time.
R154 would hold up fine if it had straight cut gears IMHO...
it would completely negate the forces on the thrust washers which are usually the part to go...

I'm rebuilding my r154 to go into my Supra as we speak. When my engine is all said and done, if my r154 gives up the ghost - I'm going T56, and not looking back.

if you build your motor much, your going to be swaping to a t56 alot sooner then you think...
HA! That's what I said... 16psi later, I'm rebuilding my motor to deal with 212k mile worn rings

true, but it seems to be only one thrust washer that gets taken out, and it's related to first gear...
get straight cut first and second gears and you'd be fine on the highway and around town...
now if only someone made them...
Someone does. They are terribly expensive, of course, and I'm pretty sure that the someone was based in Australia...
mass produce em and get em here... It should still be cheaper than a TKO and the parts to make it fit...
