I mentioned this on the 4 speed thread too. My friend has a 1996 5.9 magnum efi with full harness and computer in his 70 Duster. It also has the 833 fourspeed.
His solution was to use the manual trans flywheel for the Ram or Dakota 5.9 Magnum. All he did was to have a machine shop turn down the outside diameter to that of the LA (340)flywheel and then move the starter ring gear from the LA to the Magnum flywheel. The last thing is to drill the face of the flywheel for the pressure plate bolts.
Also you'll have to notch the bell housing to accomodate the tone sensor.
My friend is Duster7170 on here tho he doesn't post much, He'd rather do the phone thing. He'd be happy to talk it over.
If your already aware of this just ignore me. I didn't catch what your current short block is.
The magnums oil the heads thru the push rods and the LA oils thru a passage drilled thru the block and heads to the rocker shaft. so you'll need to switch to pump up lifters and hollow pushrods.
