I am on getting a 383 stroker with 450 hp (http://www.montecarloforum.com/m_13470/tm.htm#). It isgoing in a 86 ss. My question is I have a th350 tranny what parts would I need to make the tranny able to hold that motors hp and trq? I also would like to ask if anyone knows where I can get a good rear dif and drive shaft not to expensive?
thanks

You'll need all the parts necessary to conver the TH350 into a TH400, or you can buy a TH350 or TH700-R4/4L60 built for that level of torque from many shops and on-line vendors. It's hard to beat Moser for Saginaw 10-bolt performance parts. For driveshafts, you may be better off finding a local shop which specializes in custom driveshafts, since the eventual length will depend on the transmission and axle selection and chassis setup.

thank you alot Ive never had to do all this before.
thanks for your help
