So the frame is identical? I though the new truck was wider. The differentials? Transfer case? I wonder how much really could have been reused from an M809 in a RESET/upgrade program. And would the disassembly and inspection of those parts really have yielded any savings over a new build How...

Anyone here got links to good info on the history of development on these trucks? Particularly the evolution of the M939. For example, I've read that the M939 was a Product Improvement Package upgrade from the M809. Were initial M939s new production or the result of RESET mods to existing...

If that's correct, the that's only 3% more for the 003A at 5kW. And the 003A is using 57% of the full load fuel at half load. I doubt I'd get that much lower (55% would be the same as the 002A). I'd need a 5% improvement to get from 0.58gph to 0.56gph, and I don't think that's possible. But...

Like I said, that was the bane of the Cadillac system, the control electronics. Just compare the home computers of the early 80s to today's cell phones, and you get why it didn't work then but can now. Just to be clear I'm talking about disabling the semi-permanently, not turning them on and...

Did those old L8s and L6s have pressurized oiling to the crank throws? If so, you's need something to control the oil pressure., not to mention the crank imbalance from the missing rod and piston. I don't see removing the pistons being worth while on a 4 cylinder. I wouldn't expect the losses...

I own a '70 Coupe deVille and have been active on Cadillac forums for 10 years, particularly ones devoted to performance mods to the '68-76 472 and 500 cid engines. I'm well acquainted with the V864 engines. It's a de-bored 472 with solenoids that prevent the intake valve from opening on the...

Any one have thoughs on running an MEP-003A on only 2 cylinders? Trying to get a MEP-002A, but I've seen 003As going for the same or less recently. I'm new to diesels, but wondered if it might be possible to block/disable the injectors/pump so only 2 cylinders were running to reduce fuel...
