'78 need OD options
Hi All,
I'm looking into OD options for my truck. Any suggestions and questions answered are appreciated. Here's the rig:
'78 F350 Camper Special 4x2
Custom built 460. Desktop Dyno sheet0: 404/472 hp/torque @ 4500 rpm. 406 torque @ 2000 rpm.
Stock C6.
Stock Dana 70 4:10 locker.
Stock wheel/tire sizes.
I've heard the AOD can be converted to mate to this block, but sounds like much work and money. Worth it?
Looking at the E40D I learned this is electronically controlled. What behavior is electronically controlled, and can this be modified to meet my old-iron application?
Also, I have seen tailshafts and third-member units that may work, but these are extremely costly. Are these worthy alternatives to an OD trans?
As you likely guessed, this is a towing rig. I'm looking to save wear and tear on the engine at cruise (3k rpm @ 60mph), and, of course, fuel economy.
Thanks for taking the time to read, your feedback is appreciated.
Cheers,
FSH

I am not an expert on this but I would stay away from any AOD it will not last behind a 460 even if you got it to fit. I have read that there was an OD auto trans behind a 460 so I can only guess it's an E4OD. I once ran across a place that offered a computer that allowed one to install an E4OD in a no computered car/truck. Now the E4OD trans have been known to have problems. In 94 Ford had made some improvements to this trans. I still read of people having problems. This to me would indicate that this trans isn't the best for heavy work loads. The cost of rebuilding an E4OD trans will cost you almost as much as a gear venders unit which you mentioned.
If you want to keep an auto trans and want something to last the gear venders IMO is the way to go. If you wanted to convert the truck to a 5-speed then I would install a ZF. If I find a good deal on a ZF 5-speed I will install it in my 78 bronco.
