Inquiring minds would like to know, is all.

Great setup! I just plugged the oil cooler fittings on mine for now. I was told this is fine and does not "cut off" the engines oil supply. You?

I was hoping somebody could help me date my 6.2 HMMWV motor. From all the searching I did I didn't find much. All I know is it falls in the 82-91 category. Block # 1402260 No julian code on the bellhousing flange. Just numbers "231". Heads are 10137567 Lastly, the smooth section of casting...

Cool! Thanks for posting all the videos. My 6.2 HMMWV came from Many, Louisiana from a business that contracts with the Military. They do all their overhaul work since as powerplant swaps, paint and drivetrain work. I was told they do indeed pull many running 6.2's just to upgrade them to the...

I wonder if you couldn't fabricate up a header for the thing. You'd never have to deal with a cracked manifold again. Ever find out what causes this on all the GMC's? I'd heard it was the timing running too retarded.

Couldn't you just stack multiple gaskets?

The biggest issue is people using these trucks for things they were never intended to do. They were designed with 1 thing in mind. To move lots of weight over bad terrain at an average speed of 25mph. Plus, people forget that at that time there were still many unpaved roads across America where...

The show is a little liberal. But it's still the best show ever put on television. Ever. Pony pucks and horse hockey all the way. [thumbzup]

And I saved all the pics from that auction too. :D

No reason why one from an M35 won't work. They both see 24V, the only difference may be in the threading, but that is easily fixed with pipe thread adapters available at home depot.

That's all, great examples posted by everybody. [thumbzup]

Was wondering if anybody could explain how lower differential gears can lessen the load on engines and transmissions, effectively prolonging their life? Just curious is all. :D

An inch is no problem. :D As soon as I get my adapter plate I may even drop the drivetrain in to start finding any potential clearances issues before setting too many things in stone. My main concerns are the headers and the horizontal oil filter. Though the latter is easily fixed with a...

Are the GMC carbs plated like Qjets?

You are correct again Henderson, end play is measured with the yolk in place and the extension housing bolted on. In which case, mine has zero play. Funny you mentioned moving the engine forward to account for the now longer driveshaft. I was going to say, all that I would have to do is plug...

It is pretty awesome to think of an internal combustion engine setup to run 100% submerged, it's easy to do on a diesel. But on as gasser, not as easy. But GMC really pulled it off with the threaded spark plug wires and how they put gaskets and seals over every darn thing imaginable.

Thanks a lot for the tip Henderson. The yolk was indeed seized onto the output shaft. I picked it up by the yolk on the crane and a few taps with a mallet broke it loose, it slid right out. I am not sure just yet what caused the yolk to seize up. But here's my findings so far. With the...

Holy crap, I think you may be right henderson......all of the "slip yolk" output shafts that are for sale for Th400's look just like mine. I think it has indeed frozen itself in place and with some work it should slide out.

Well, crap. Can anybody take a guess and point out what the problem will be with this Th400 output shaft? No slip yolk. Will this be a problem for my street use or should I just not worry about it? I suppose if there was any give in the system the trans mount would provide some flexing.
