My 92 F250 460 has only 44k on her but is noticeably lazy. She only has the 8.5 CR and I want to either wake her up big time or install a coyote. I have been told that AOD wont accept any significant mods. Incedentially I have a great 97 F250 (wrecked) w/460 AOD available. I am an old guy so confess to being clueless. Thanks for any help that you can offer me.

Start with headers and free breathing exhaust from banks.
Low restriction air cleaner element and top. Don't leave the element open to under hood heat.

Check and adjust initial timing with the spout connector removed. 10 is oem. bump to 12 to 14.

88 to 92 EFI engines have E7 heads with rather small intake valves at 1.980"

The platform is easily capable of supporting 400 hp give or take. We build them frequently.

Start with the aforementioned mods and see if this is enough. If not a top end kit with better flowing iron heads, ported intake and a custom EFI grind will turn up the torque and power from there.


Finally. The E4OD is basically a C6 with overdrive and a wide ratio 1 / 2 gear set. Properly built with some valve body upgrades is is more than capable of dealing with upgrades.

I have an '89 F-250 and am experiencing the same lack of power. I'm going to install the banks headers. I believe I have a C6 3-speed transmission though. It bothers me pushing 2800 RPM at 60mph. Can my trans be modified or do I just have to get a newer trans?

Thank you for the information. It would be the perfect, although expensive, solution. However, I have a 4X4 and their application only works on 2 wheel drive. Is there a later 4+ speed transmission that would work on my 4X4 '89?
