I have this project posted up on a few sites, but i figured it would be good to get it going here. There seems to be a lot of knowledgable people here who have great input!
I bought the donor 2nd gen p-pumped 12v cummins in the beginning of January. It has 150xxx on it with a fresh pump. I got a brand new nv4500 5speed tranny, married transfercase from the truck the motor came out of (blew a tranny), Valair clutch good for a 500hp and 1000ft lb of torque, and an intercooler from a 2000 7.3 powerstroke. Then i bought the truck towards the middle of January. It is a special order F350 Crew Cab long bed with factory ac. These trucks only came in a crew cab longbed 2wd and crew cab short bed 4wd. I found this one that had already been converted to 4x4 with hi-boy front suspension, a dana 44 with big knuckles and big discs, and all stock 4wd steering. It was quite a score. From here i have torn out all of the stock drive train; a fresh 390, 4 speed manual, and a divorced np205 transfer case. I built a custom tranny crossmember and engine crossmember out of 2x4x.25 steel. All of the fab work was done with an old school Lincoln arc welder with 6011 rod. This makes for EXTREMELY strong welds, but not pretty ones. The motor mounts are also made with .25" steel. Here are some pics of the progress:
Front clip off and stock front crossmember rough cut out.
Everything is getting ground smooth right now and ready for paint. Should be able to do that this weekend. The engine crossmember and engine mounts are welded into the frame. I didnt see a point in making them bolt in. For the tranny crossmember i welded 18" plates .25" thick into the frame and then put 14" plates .25" thick on the crossmember that bolt up to it. The point of this is to stiffen the mid section of the frame to prevent side to side roll.
I will be turning the pump timing up to 17*, building a custom "boost controller" to run 35psi, #100 fuel plate, 3200gsk, and afc mods. I should be able to get close to 450hp and maybe 800-900ft lb of torque with the stock turbo. Once i can afford it i will be going to twin turbos, 5x .014 injectors, headstuds, and 60# valve springs for making well over 500hp and 1000ftlb's. Im hoping to have this thing on the road in the next 2-3 months, but we shall see.
Im sure i have left a lot out, but there will be more to come soon! Engine should be mounted with in the next 2 weeks. Just waiting on the flywheel mods for the new clutch. I hope you guys enjoy!
