That is a great write up and will help me and many others I'm sure. Any way someone could get the pictures showing again?

These engines have crazy good torque right off idle. I rarely touch the throttle in technical parts of the trail, even if it is a decent uphill climb. If the tires will catch traction, she will go up the side.

My 6.2 makes 40-45 psi at idle. Good luck pulling it down under the idle rpm it's governed for...the more you try to pull it down, the more fuel it'll add to try to maintain idle speed. That is one of the reasons they work so well off road with a manual tranny. I wheeled about half of Pritchett at BB '03 before nuking my rear driveshaft. Everything even remotely technical I did with my feet flat on the floor, at idle. If it...

Hey, thanks for your help. I already stumbled across that, there's an excellent write-up on the dieselpage of a guy who put the p400 in his new body style k2500. he also had him built a custom oilpan... I need to have that engine!

The 6.2L is nice, but you must remember which state you live in. If you change out your motor to a diesel and its registered as a Gasser with DMV, well then your off to the referee station next time around for smog. If your truck is clean, just swap in a nice 305 short block. Then if you want to get good milage, sell your truck and get a 6.2L diesel truck. Or you can go the way of us outlaws and get a CUCV military blazer... My CUCV is...

As I remember this the external locations of parts is the same. By that I mean where and how things bolt up. I don't know about the accesories though. But those aren't killer to find. My question is more about the electronics on that thing. In short marrying the truck to the engine, I know its doable, but are you able and you do live a long way from the local junkyard here

Hunting, fishing, rock crawler, go anywhere toy.

don.t want too high jack ,but i,am thing very seriously of doing this swap to my truck. would like to know what years and models of donar truck?it would be for a 1977 3/4 ton 6.2 sm465 looking for more speed 410 ratio.

'95 up are easiest if you have no lift, they have the internal slave. late '92 to '94 will work with a 4" plus lift or if you use an adapter bell to run mechanical clutch.
