Need Help?

I have a stock ls1 with an upgraded STS Kit w/drag radials. I just purchased the SPEC stage 3+ kit with the steel fly wheel and aluminium preasure plate. I am upgrading the turbo to a T70 and putting in a 383 stroker sleeved that will hold up to 20psi of boost. The question is how much HP and TQ will the stock transmission hold as well as the stock rear end? I know I am going to explode them so which rear end and transmission should I go with?
Thank you

The only problem with the tranny that you are going to have at first will be teh 3/4 shift fork. Have a good tranny shop go in a upgrade everything in it. My buddy had his done for about $1200. The rear will explode. I would put a rear in it first thing. Either a Moser, Strange, or a 9in Ford.
