Cummins swap opinions needed

[bad421]

Thanks guys. I'm pretty sure that I will end up doing the swap. I don't think that I'm going to tear the k10 down to do it though. I have a rust free 67 cab and front clip sitting in my backyard so all I need to find is a bed. I have already swapped turbos and added a intercooler and 5in exhaust into a 6" mitre cut stack and tweaked the pump a little. I'm tossing the idea around about keeping the chassis a dually and graphing on a set of stepside fenders . What you'll think single wheel or dually? Thanks to all again.
