I have an m1008 with a 6.2L i want to put the 6.6L LB7 in it, is their a kit or can i just swap them and get a new harness?

Isn't that motor worth 5-10 times more than the truck?

The Izuzu diesel makes a lot more hp than the 6.2 or 6.5 GM diesel does. You would have to replace the transmission and transfer case or it will suffer an enrly demise.

As for a kit to install, I'm sure someone does, but you'll need to also need to replace the instrument cluster as well as an ECM.

Not practical unless you have a endless supply of time and money on your hands.

where can i go to build my 6.2 then?

You would be better off getting a second engine and then rebuilding it. This way you can still use your truck while the rebuild is taking place.

I have a 6.2 running take out engine if interested.

If you want power and you had money for that Isuzu motor why not go with a Cummins 5.9 ISB? These have been done before and finding parts will be a lot easier. You can find a wrecked truck with one in it and go from there. Plus with after market support the way of plug and play modules, injectors, etc etc you can get a lot of horse power and torque for not much money. Plus adapters, engine mounts, etc should be readily available.

Get a banks turbo and turn up the fuel 1/4 turn. You and your wallet will be happier.

chevycrawler,
Have you explored option to install IHC motor?
I think DT466 will fit very nicely. If DT466 is not available DT360 is not bad ether.
You can buy one of this out of school bus for about $1,500 - $2,500. And if you choose earlier then 1994 no electronics needed. You also going to need a plate to fit from your SAE2 bell housing to your trany. I guess $500 or so.

DT466 can pull up to 300 HP 600 Lb/ft @2,000 RPM without changing parts just tune it correctly. Up to 600HP upgrading turbo + adjustments. If you are picky, for about $5,000 upgrades your can reach limit about 1,400 HP.

DT360 is the little brother. Smaller dimensions. It has almost the same (-10%) potentials.

Think about.

I forgot to mention that the LB7 had problems with their injectors that GM warrantied for something like 7 years. I bet they won't with the engine in a 198something swap job. Just something to think about. Do you have a wrecked Chevrolet/GMC with the diesel motor in it or something?

An M1008 is a CUCV, basic 3/4-1 ton pick-up truck. If you fins a way to shoe horn a DT-466 into one of these, please post pics.

The LBZ doesn't have the injector issues the LLY had. As for the DT vs Cummins, have you driven the two? The B will run circles around the DT. I have had both on the dyno and the B is a much harder running engine and has better holding power. The DT makes OK power but falls off very fast.

If it were me, i'd do a 230 HP mechanical B with a P pump. The VP44 ISB is a noisy, expensive pig. But what do I know

 

[eric_banks32]

I say go with the D-max. As far as everyday drivability and mileage it far surpasses everything else. There isn't a kit as far as I know but mounts and crossmembers arn't hard to make if you have the right tools. The hardest part would be the wiring. You will also wan't to keep the allison if you can. But I'd love to have one with a nv4500 behind it just to add to the fun.

 

[MidnightDuramax]

The Duramax would be the best in my opinion. You can run an Allison behind it if you have the money to burn. I do know they put the 4L80E behind the Duramax in the vans. A company called PCS makes A harness for the 4L80E and i believe to also make one for the Allison. As far as the engine harness I'm not sure.

There were a few ( good luck finding one) Chevy pickups built with a Cummins and I believe they were in the 1980's.

 

[4bogginchevys]

Never heard of one, do you have a link to one built factory w/ a cummins....

I'm pretty sure a Chevy pickup (one ton and under) never came from the factory with a Cummins engine in it.

 

[MidnightDuramax]

I have never seen one either.

Do a search in this forum. Somebody posted a brochure for a special order Chevy trucks with a Cummins in it. It obviously didn't go over very well or GM would have been on top of the Cummins contract instead of Diamler Chrysler/Dodge. I do know they made plenty of the P30 vans with 4BTs in them.

My opinion: If you're set on a motor swap, I'm very happy with my Cummins swap. Stick to the VE or P pump motors, I'd never purposely put a VP44 motor in my own truck and it's really hard to beat the realiability and power of a P-pump 12 valve. The Duramax swap would be nice, that's really what I wanted to do, but the Cummins needed less than 10 wires to make it run, function properly, and work all of my gauges. I'd imagine a Duramax would need a few thousand and would be well over triple what a mechanical Cummins would cost. Not to discourage you, just to inform you. If you have the time, money and resources, I'd love to see a Duramax swap! I'd be very jealous and I'm pretty sure it'd haul asses!

I would go D-max. It my own personal opinon but I think they are better. As far as the early 80s deisel, my owners man for my pu says a Detroit Desiel.
