Diesel Dart Cummins

I just rebuilt the 47RH in my 92 D250 Cummins. I used the Red Alto clutches and Kolene steels. Along with a Transgo Shift kit and a custom HD converter from out west. Reason I rebuilt mine was that it was suspect, and I wanted to boost the stock IP. Trans worked out great. Last week I put in a 3200 Gov spring and A Denny T fuel pin. The power increase is unbelievable. I was shocked. There is a lot you can do with the Gen1 engines. I think I'll stop were I'm at so I don't start breaking up stuff. LOL
