Help Building A Transmission
 

Hey guys I own a Challenger SRT8 392. I currently have an Edelbrock Supercharger inshallah along with bolts on making 575RWHP. But I admit I am an addict and I want more power. So I think I'm going for a 426 Stroker (excluding the heads), probably a 90mm TB, and maybe a water/methanol kit. So that brings me to the transmission. I have an auto tranny and I know for a fact that the stock tranny can't handle all this power. So what I need from you guys is advice on where I can find the right parts to rebuild my tranny? Shophemi.com only offers full on trannies and not the actual parts which is obviously more money. So any advice on this issue will be a major help.

Thanks in advance
