I think you'd need to extend the front end of the truck a little as well as the firewall to get an inline 6 cyl diesel engine to fit (8.3 liters...yikes!). Now the 4bt Cummins, that may be a different story. 3.9L Turbo 4cyl, can be found in a lot of old GM P30 aluminum box vans (strohman bread trucks). Coupled with the 4.3L tranny/transfer case...hmm... <img src="/forums/images/graemlins/scared.gif" alt="" />
