Umm.. Maybe I have missed something, but the 4.3 and 2.8 should not share the same bellhousing. 4.3 is a 350 v8 with the rear two cyls hacked off. Something I ran into while playing with the idea of using the camaro 3800 v6 with the 4l60e trans.

He is using a 4.3 diesel, not the 4.3 gasser you are thinking about. It has the 60deg bell, I'm using the 90deg 700r4 in my conversion.

Its the 4.3 L V6 diesel out of an 84 Olds Ciera.

That's pretty cool. I knew they existed, and have seen them in the station wagons, but assumed they were the same blocks as the gassers.

Embarking on my own OM617 install soon in a 1988 Grand Wagoneer. Glad to see other people are doing it too!
One comment; Mercedes flexplates/tc's use SIX mounting bolts, probably due to that if you only use 3, they will loosen/vibrate/break. Something to consider. I think 1/2" to maybe 3/4" by 1" wide solid plate steel strips welded to the converter of choice and drilled/tapped to accept the flexplate bolts would be my preferred method.

Oh, I have read every post of every diesel swap thread in multiple forums. Trying to keep myself from having similar problems. The problem I had with the original blocks would be that I would have used solid steel blocks and drilled/tapped them...also weld them full circle to the converter. I thankful for you to provide so much info here(trying to avoid the $925 adapter, though it may be cheaper that way in the long run).

I think i'm going to break down and buy the kit. It will save quite a bit of time, and i'm to the point where I want to drive the thing instead of working on it. After two failures, i'm ready to try something else!!! Good luck with your project, keep us posted!!! You should have much more room to work with in a Grand Wagoneer too!

I dropped the trans and transfer case out of the Jeep tonight. No damage to the blocks I welded on to the torque converter. No damage to the flexplate or centering bushing. The problem must be inside the torque converter. I fired up the engine without the trans to make sure it wasn't the engine. The engine runs strong, no noises. I think it's time for a 700R4!!
