90's Viper T56 in a Firebird

[67rstbkt]

I've got the chance to buy a used T56 from a 90's Viper for $950. Is this a good deal? Can I use this in my 67 Firebird (400 motor). Anything in particular I should look for? Power holding potential? I can get the casting numbers if that helps.
Thanks

*Edit* I've been trying to research more info without much luck. I know that the input shaft would need replacing for an LS motor, but am having a hard time finding out what I would need to mate this to a Pontiac 400. I have found crossmember stuff, but no bellhousing or adapter plate info. Can anyone point me in the right direction? Thanks again.
