Chevy never did use a 2 stroke diesel... Many locomotives untill recently used 2 strokes and the old Detroits were 2 strokes but for the most part 2 stroke diesels are a thing of the past.

Actually, I think Chevrolet owned Detroit at some point, hence many of the C60+ trucks had an 8.2L Detroit in them. I think those were all N/A however. The 2-stroke V-6's, V-8's, and V-12's of the 70's were actually powerhouses when turned up right, and can actually turn fairly high RPM's. There used to be a pulling team (the LongHorn, a conventional, and the StageCoach Express, a COE) that ran V-12 Detroits.

He's turning about 4200 RPM in that video.

Yeah but those v12s just don't compare to the Cummins I6 as far as frame twisting torque goes. In think they're turning them around the 4500 mark as well, I know theyre hitting 5500+RPMs with the 6BTs right now. Although that V12 was probably the most impressive Detroit puller Ive seen yet.

And yes I believe DD and GM are/were related, I don't recall any detroits used in stock pickups though... GM owns EMD the locomotive makeer which used huge 2 stroke diesels in their locomotives.
Heres a video of under the valve cover of a v16 train engine running, I took it while on my BNSF internship.

I've seen 4000 fully fueled without any internal modification (MADS Smarty), but to get to 5500 you really need a different valvetrain. Since most of those classes require factory cams, the I-6's don't usually turn as high. I'd be surprised if the Diesel Doctor in that video was turning much over 3500rpm. Got any further information on him? I know Larry Carey (Dodge Fever-KT1150 Cummins) only turns about 3100RPM.

My 5.9 sounds VERY similar when wound out to 3100RPM, sounds like it wants to come apart, but the power is definitely there....

Ah, I finally get to use this one:thefinger: J/K

As for the question and hand, lowering is for 2 wheel drive go fast type of stuff. While lifting is for added performace while off road.

Now both can be done for real life performance gains or for just the "I wana look cool" gain. For real life gains it usually costs more then to just get the look and not really need it.

Also in my opinon any 4x4 truck that is lowered has had its balls cut off.

I know the old detriots they put in tractors (Oliver Super 99 and such) had a big "GM" cast into the side. They are neat for a little while but get very annoying in a hurry, way too much noise happening for a open station tractor within a couple miles of spectators. That was back in the 50's-60's, I think they were a 2-stroke 3 cylinder supercharged engine.
