99 trans am roller
i didnt know how well these engines stood up to nitrous, i know my 5.9L can handle a 200 shot, although its a heavy duty engine lol. i was thinking a 125-150 shot, just left in, incase i found a mustang or something 
wish i could afford them, but i need the car first lol. those are the ones i was looking at actually
i checked, and its got a shifter setup for a powerglide trans. should i just go with this, would it be better then a 6spd?

If you really want the six speed then get it. A stock T56 will fail if you drive it too hard but you could baby it and make it last.
you can break a t56 with close to stock power... me and PLENTY of people have ran 4l60s with 400+rwhp for a LONG time..
built transmissions.. no reason to argue that, either one can out last the other one.. but "equally built" the automatic will last longer in 99% of setups..
i have a built 4l60e in my car thats is rated to 650hp, im sure it would take much more abuse than that..
not trying to say "your wrong" but i HIGHLY disagree with that..

^^^ not saying your wrong either, but I also disagree 
The reason the t-56 will break first isnt necessarily its weakness, but rather bad driving. Missing a gears, grinding gears, that is more likely to break a t-56 than torque. There's a procharged camaro that runs high 9's with a stock t-56, not likely to see that with a stock 4l60e.

either way.. in the hands of 98% of people the 4l60e will last much longer..

I believe I found that video a long time ago linked from a thread on here. If I remember correctly, it was a completely untouched t-56. That was the first single digit run if IIRC because he was afraid to shift that hard. You are correct tho, in most cases it will last longer, but thats still driver error lol. for straight line racing... you can't beat an auto. I'll look and see if I can dig up the thread.

I'd consider it a stock t-56, just aftermarket clutch. thats like a stock 4l60e with a nice stall converter, still a stock 4l60e... Just my opinion tho.

Verdad Gallardo its internally stock. change of clutch/clutch hydraulics is very easy. a stock clutch wouldnt hold a bolt on car with a small shot.

in my eyes.. a converter hurts a 4l60e more than helping it.. as far as life expectancy goes..
as for a clutch, its makes the t56 stronger..
guess its whatever your opinion on stock is..
like is a lid on an ls1 still "stock"?

and fwiw unless you go into the engine, most people consider it stock. same with the trans. the trans isn't any stronger unless you go into it. Your just making it more efficient with better clutch/flywheel/master, not stronger.
actually you're quite wrong. a good clutch will hurt a t-56... the better it grips, the more shock it transmits to the gears. A stock clutch will prolong the life of a t-56 by having some slippage (slipping wont heat the trans fluid in a stick, unlike a slipping converter in an auto). Same with the fly wheel, light weight fly wheel means less hp loss, more drive train shock. Same with hydraulics... the stock master cylinder limits hydraulic flow under WOT, making shifting quickly damn near impossible. A tick adjustable master cylinder will make it much easier to slam gears, also adding stress to the trans. Lemons, you really know your stuff with the LS1, and 4l60e, but you severely underestimate the t-56.
thats why when people ask me on it i just say im not going to comment! i know my limits!
