90 F150 Cummins

A few pics of my project. As it was before surgery, setting up the mounts for the Cummins 3.9L diesel from a Frito Lay van, after total diassembly of the frame, boxing and plating and hot dip galvanizing, reassembled with 9" rear, solid Dana 44 front, epoxy and urethane over the hot dip, it will last forever.

Seven lbs of wire later. Had to totally gut the corners, made new running board extensions and support structure from 16 ga.

I used Fusor panel adhesive and rivets to eliminate any possibility of warping.

Looks nice but why a 3.9 Cummins ? Not much power there for your truck . Not knocking it just wonder why .

They've got plenty of power. 130HP stock, turn up the fueling on the pump along with a turbo off a 6 cyl and 175 hp is no problem and with torque close to 400 lb-ft @ 1700-1800 rpm. Plus high 20's mpg. Much better than the gutless 302 that was in it that was 165 HP but no torque to speak of unless you wound the p&* out of it. Plus I'll have 9 forward gears with the Gear Vendors overdrive.

Nice looking work. Are those rivets holding that patch panel in place? If so can you post a closeup of one of the rivets and the tool that is used to install them? I'm not a big rivet fan because welding works so well but I'd like to see if you have any problems after the vehicle is on the road for a year or two.

I believe HP rating was with a turbo on the later 3.9L/4BT cummins.

I would look for a turbo off of a 3.9 engine. It is an interesting swap which has been done many times . I would really like to hear what the top speed is when you're done . I know the MPG will be good as some guys have said 27 to 33 MPG .

Looking forward to some pictures when you get to the engine part .
