O.D. trans conversion???
I'm looking at a 1977-1979 F250 460 C-6 trans. With the cost of gas I want to upgrade to a 5 speed OD trans. Auto or manual. Any comments or suggestions.
I live out in the country so most roads are 50 MPH or greater. I still need the towing power for a animal trailer and car hauler. I think leaving the differential gears the same would be best, but getting an OD would be best like .76:1 fifth gear. (4 th gear in auto I guess)
Ok what if I also added F.I. instead of carb as well. Would this help or to costly?
Thanks in advance to all who reply.

If you have a 4x4 the swap to a Dodge NV4500 seems to be popular, and I've seen a lot of info about them in the Transmission area.
If you have a 4x2 there are a lot of options to basically any transmission you want with the new modular bellhousing's from McLeod industries, www.mcleodind.com. For example, I'm in the midst of gathering parts to put a Tremec TKO behind my 400M in my hotrod.

AOD Tranny
hey man, If you want any help at all with Trannies, call Scott at Phoenix Transmissions, that guy knows what he is talking about also he will make the tranny in any gears that u want, you tell him some basic specs about what you are doing with the truck and he will advise you what you should use. And u will get a 2 year warranty http://phoenixtransmission.com/
There is a phone number on this website, seriously check them out, i have had my tranny in now for almost a year and not a single problem, and i race from time to time so i told him what i wanted it for and he built it for me.
I bought an AOD for my 1976 F100 Custom and put in a 302 from Jasper Racing it is pushing out about 350 Hp, after the AFR heads are on it will push 450 HP @ 780 FT LBS of Tourque, i do have some pics of my truck on here somewhere, but i cannot seem to find them, if you want them let me know ill send them to u Talk to u Soon.

Is it 2wd or 4x4?
A trans from any newer pickup with 460/OD will fit into yours with some work. With a manual, you will need to fabricate a hydrolic clutch - which has been done, search the past threads. For a newer auto, you will need a stand alone computer to control the shifts, which can be bought from several aftermarket companies. Both will require fabbing a crossmember and custom driveshaft.
If you want EFI too, then the easiest may be to get a newer wreck with a EFI 460/od and swap the entire drivetrain, wiring harness and computer into your pickup.
There's 2 good tech articles you should read - link at top right of page. One is swapping a '88 EFI 460 into 73-79 pickup and the other is swapping a OD trans into a '79 Bronco (which is the same drivetrain as a pickup).
Be sure to count the costs. I've considered the NV4500 swap into my '73 390 and it'll run me about $1500 for trans and extra parts. It'll take 5+ years to recover that cash through gas mileage savings... But it sure would be nice.
