Duramax Diesel Engine Conversion Kit

Found the following;

"gm square body duramax diesel engine conversion '73-'87 C & K SERIES......"

Looks like simple swap and bolt and to me it does not look expensive{the conversion parts/kit] compaired to fabricating everything yourself.

I have no interest in the company, only a possible purchaser of the kit.

For the price of there motor mount kit, you could ad a turbo to the old 6.2 and turn up the pump, that should add almost 100 HP. then for another 600 bucks add a water meth kit and that should add another 60-100 HP. that should put the HP and torque right around a stock duramax. for only about 1000 dollars. A lot cheaper than buying a used duramax and transmission.

FWIW.....

I have a 6.2na in a 86 M1031 and a 6.5 turbo in a 99 Suburban.

A Durmax is a much better engine.

A Durmax LML with a 6l90 or better yet a 8L90 in the M1031 is what I would like.

Would make the M1031 a sleeper.

Agree and not to forget the TCM and other small trinkets. Mine just started to go and it cost $650 just for that plus $300 to program. I am glad I added the Edge Insight CTS2 as I can clear codes while on the fly as I had to do when the TCM was getting tired.
My TCM went out in the yard one day for the last time and would not go in any gear plus I could not clear the codes. I shut her down unplugged the TCM and plugged it back in fired her up. She was working again so off to the dealer I went for the new one.

Besides the electronic complexity. Where would the intercooler go? I know if a radiator gets a nip and a tuck here or there. That an early year Duramax intercooler with a few modifications can be made to fit after the entire front valence is reworked. However, that is for a 6.2 radiator. How much more capacity does a Duramax radiator need to be to cool the extra horses?

I think the idea of the kit is great and that 20 years from now it will be the normal square body modification. Kind of like the "Put an LS into a '57 Chevy" stuff you find everywhere these days. I'm just pointing out some of the required items to get dependable long lasting use of the swap that don't seem to be addressed yet.

Would be cheaper and easier in the long run to just drop a 12 valve cummins and a 47rh trans in it. Probably only have 2 grand into it. Plus you only need 5 wires and your up and running.

I don’t think I’ve ever come across a running 12v for $2k. Usually double that

Several 12 valves on Craig's for under 1500. Bought mine for $1000

Seems very reasonable. Particularity time/materials to fab.

Must be a regional thing. All of the bodies/chassis must have rotted out around them so there’s more drivetrains available where you’re at.

I agree with the Duramax being a much better engine... my 04 GMC 2500 Duramax truck moves on down the road with very little right foot on the loud pedal. Having said that, I **** sure do not want that much power in a 1985 M1008. I'd wind up wrapping it around a tree. I'll stick with my factory 6.2 naturally aspirated....

I miss my duramax. (And the Cummins I had) That said, my 1008 will retain a 6.2 (but I did turbo it). It is what it is. The only creature comforts and upgrades to the 1008 will be a 700R4 or 4L80e, radio, cig outlet, and maybe AC. If I want another Duramax, I'll buy the truck that matches to get a much more comfy ride. The other factor is, I question the frame/suspension being up for the task for a long term run.
