How much power can the stock 5 speed take?

i hate my nv3500 in my rst, ive been wanting to put a t56 in it sence the first week i bought it

What don't you like about the nv3500?
I'm guessing the nv4500 1st gear is a granny gear? Start out in "2nd" for unloaded daily driving. Anybody know 5th gear ratio in the 4500?

I finally slipped my clutch the other day, but I was beating on it and it was after about 15 donuts, I have a brand new TKO 600 that Im swapping in with my 6.0. I really dont care for 6 gears and it will hold a helava lot more than the t56. I have everything for the conversion and with the mid shift location on the TKO the shifter is in the same place as factory instead of between the seats. I will let everyone how the swap goes and how I like the tranny.

I believe it is the same NV3500, but with a better clutch.

Does anyone honestly think GM or Joe Gibbs have gone out of their way to remove the transmission to upgrade the clutch? I don't hardly think so.

when I had my 92 excab with a 4.3 . . . I got 100K out of the stock setup.
Then after I lifted it, 33s and a 3.73 in the rear, it lasted 15K, after rebuild #3 it lasted until 243K when I sold it. Even then 2nd gear syncro was FLAT !
