Will I blow up my M21 4-Speed?

[Dub J]

Im worried that the M21 Muncie 4-speed that I bought isnt gonna last behind my small block 350. I was reading some horror stories on the board about guys that tear their M21 4-speeds all to hell when they power shift or dump the clutch (which I plan to do). I really like the idea of a straight shift in my truck, and dont really want to spend $2000 on a TKO500. Whats the next best alternative? Will I definitely blow the muncie up? I'm building a 350 .60 over with patriot 64cc aluminum heads, Comp 286 cam, Edelbrock Air gap intake, shorty headers and 750 double pumper. Im thinkin this motor will put out atleast 350-400 HP right? Is that too much for this lil tranny?

Has anyone put a T56 in from a Late model camaro? I'd love to do that, and saw somewhere that it could be done but couldnt find anything on the board where anybody has done it.
