72 gmc duramax build

Hi thought I'd start a build thread on my current project. It's a 72 gmc that I've had kicking around in my back yard for a couple years now. I also had a bunch of duramax parts leftover from previous builds and figured I might as well build something with it all. Frame was an 05 3/4 ton reg cab with 6.0. Stripped it down and moved axle ahead about 6 inches. Also had to put a shortbed fuel tank to clear axle and added a fass fuel system I had

Re: 72 gmc duramax build

Cab floor was rusty so I ordered one piece floor cab corners rockers and kick panels. Last weekend I cut the floor out. A few hours later cab floor was tacked in place and cab was set on frame.

Re: 72 gmc duramax build

Sat the engine and trans in and then lowered cab onto frame to see how it fit. The floor fits the new chassis nicely. The bed floor will have to be raised about 4.5 inches to match cab. Engine is an lb7 with 68mm turbo profab manifolds and uppipes. Getting some bigger nozzles for it also.

Re: 72 gmc duramax build

Very nice work so far! The one piece floor replacements are great. I sprayed my new floor top and bottom with raptor liner to protect the new metal. How did the cab mounts line up on the duramax frame? Great choice on the LB7 too, I love my deleted LML daily driver.

Re: 72 gmc duramax build

Thanks. The front cab mount lines up with an existing hole in the frame. I just had to drill it bigger and pass a long bolt straight through. The rear mount interfere with fuel tank so I had to make new mounts I'll post pics when I get a chance. I wanted cab to sit lower but the rear is sitting on the fuel tank so without relocating fuel tank it's as low as possible.

Re: 72 gmc duramax build

Built a new filler neck this evening. The only logical place to put the filler was back in the original location but seeing as tho I wanted to keep the new style tank I had to pass a pipe through the cab. I welded the newer filler neck where the old cap was and an exhaust elbow to back of cab. Hooked up the hoses and done.

Re: 72 gmc duramax build

Got the radiator support mounted and fit the radiator and intercooler. It fit tighter than I was expecting. I'll have to mount an electric fan in front of the the radiator stack.

Re: 72 gmc duramax build

Thanks. Not as much progress as planned this weekend but I did run fuel lines and trans lines. Going to hook up radiator and intercooler piping this week and hopefully tackle engine wiring. Should be running by the weekend

Re: 72 gmc duramax build

Got a bit of work done to truck. Intercooler piping is done as well as coolant hoses. Mounted throttle pedal and built shifter linkage. Also wired up engine and fired it up. Just need to build a driveshaft and I'll be able to move it around

Re: 72 gmc duramax build

Yea it's a nice change of pace. Done so many ls swap they were kinda starting to get boring. Took a short vid of first start last night. Wiring is mess going to mount battery pcm and tcm and then clean up harness. Link to vid https://m.youtube.com/watch?v=inFJgk2cx4Q
