We are looking at upgrading from our 7.3's to something newer and I need suggestions. First off we want to stay with fords but 6 liters are out of the question due to long term reliability and 6.4s due to truck cost. So what we are thinking is buy 3 05-07 fords like what we what trim wise but with blown engines and swap in the all mighty Cummings. What's everyone's thoughts? Does the 5r100 have any stand alone controllers available? Looking at starting this project late this year after fall harvest so I haven't done much research yet just wanted to get some input on this.
