Hope this goes well,1st post to the TDR. Converted my 3500HD Chevy diesel to the Cummins. Running a 3053A Spicer 5-speedw/13inch GM clutch. I am in the process of getting my pix downloaded in case anyone interested in seeing them. The truck now weighs with full tank and driver 9370lbs,up somewhat from the stock settup,but with this awesome engine had no trouble with 11,000lbs(a personal record) of gravel added to it. You all at the TDR have been a great source of info. Thanks a lot.
