Ford 460 to 6 speed

Hello all,

I found this forum to read about stuff for my dads 08 F250. I am not in the position that I am building my own CJ6 JEEP. I need a power plant for it and I would like an EFI 460. I am just waiting for the right one to pop up. I would also like to use a 6 speed from the Ford Super Duty's.

the ZF SF650. I have googled and searches this site and come up with 'im sure its possible, just need to spend thousands and find out' Im more interested in someone with actual knowledge or info for me. Before I go purchasing trannys and parts. I am almost 100% settled on the 460 but the tranny can change.

Reason for the 6 speed is I need to be able to turn over 37s with 5.13s in the axles while also getting reasonable gas mileage/RPMs on the interstate at 70mph since its going to be driven alot with the nice weather.

Thank you all for any help you can offer.

Ben

Richmond amd TKO have tough as nails 6 speeds. They should be tough enough and more swap friendly.

Im not counting them out, but the gearing I need/want just isnt there. The 4.41 just isnt low enough of a first. Id like a Min. of 4.7 and an O.D. in the .7 range or better. The SF650 is as close as I am going to get

I guess more or less what im asking is, would it be cheaper and easier in the long run to try and cram a diesel in there since it matches the tranny than try and adapt it?

The ZF 5 speed that came on the 460 efi trucks would be your best bet. It has a 5.72 first gear and .76 OD.

Ford 460 to 6 speed

In 1963, I very successfully installed a Ford 390 in a CJ6. I used a Ford T10 4-speed transmission, and the stock transfer case. I purchased the CJ6 new, so opted for 4.27 axles, which worked out great. I also installed an overdrive from a 1950 Studebaker which only worked in 2 wheel drive. I purchased the transmission mainshaft to adapt from the T10 to the transfer case from one of the hot rod parts suppliers of the time, I believe it was Brian Chuchua, but I could be wrong. This was a very inexpensive conversion, that worked out really well. I put about 80,000 miles on this vehicle, and (since I used to be **** about car costs) got an average of 13.5 mpg during this period. It was fun!!!

I will agree with 97puller, in that the zf5 will be a better choice. It was available stock, so there will not be a need to 'adapt' it to your 460.

For the interest of conversation, why the choice between a 460 and a diesel? And why are you set on a 4.7 minimum first gear?

The 460 zf5 didnt have that low 1st gear. At the time they had the zf5-42 and had a mid 4 1st. The stroke -47 model had the lower 5.72 1st gear. That being said, Id suggest a t19 with a gv od or an idi diesel with the zf5-47. Ill say one last thing, this is from months almost years of research but no expiriance. I havent found anyone who has done a zf6 behind a bbf because they dont share bolt patterns.

I'm a little confused... I have the 460/5spd with 4.10 rear gears and running 39" Mickeys. 1st gear is a creeper gear, and I can pull a Boeing 747 with it, and I can run 70mph without even breathing hard. So why the 5.13 gears? Are you doing some mountain climbing or rock crawling?

zf 5speed simple! But?

your other option is the TCI 6speed auto. can make it a manual automatic i guess and a divorced transfercase. Kinda expensive but they make with a detachable bellhousing for big block ford or small or dodge, you get the idea! something else to consider. just did a zf 5 speed to a 400 ford and lots of work and thinking to make happen. considered the 460 but wanted a little better fuel mileage and used the 400 with some serious upgrades. good luck! trick to fuel mileage is less weight and tall skinny tire. less rolling resistance. good luck!
