Cummins made the truck. My engine was not a Dodge 12V, but one from a International Rollback wrecker. Only turns 2500 RPM. Adjusted the fuel plate forward 10mm (@300HP) I have put 165K on the conversion/280K on truck. Just finished a total rebuild on the front end, new tires, new bearings, ball joints, rotors, pads, tie rod ends, both pitman arm and mount, and torsion bar mount kit. Drives like a new truck. Pulls better than a Dodge Cummins and rides like a Silverado. Performance has outlasted my paint. Wayne [Reply]   [No Email]

AC pump needs trimed to fit. Every frame cross-rail from engine back has to be moved rearward and drilled/bolted. Rear driveshaft shortened and front lengthened. I run a 18" solid fan flush mounted with short cummins fan mount. Stock radiator. Tach runs thru the alternator. I keep thinking about cutting my radiator support and mounting a Cummins Dodge 2004 intercooler in front of my radiator (have it). I run 4" exhaust. Mileage is same or better than 6.5 16-20 empty, @14 towing. She has pulled more than the average pickup. Had a fellow ride in my truck who owns a 2003 Cummins Dodge. He was amazed at the ride quality and comfort. He had ridden in my GMC Topkick and he likened his ride to my Topkick. I'll do another converson if I every wear this one out. :) Wayne [Reply]  [No Email]

Yes 300. All I did when I dropped the Cummins in was change the downpipe. That 6.5 with a Peninsular diesel boat injector pump and turbo would run circles around this 5.9 empty. HaH, Not loaded. And it would not hold up. Made more out of it in parts than I had in it. 6.5 = P.O.S. Parting it financed my conversion. [Reply]  [No Email]

Had everything installed back in 94 and the hood wouldn't close. Cab lift kit is super ez to install, and improves the truck appearance; IMHO. [Reply]  [No Email]
