Description


As Seen on Xtreme 4x4 - This adapter allows adaptation of a GM automatic Turbo 350, 400, 700R4(early 4L60E with a one piece case) or 4L80E overdrive transmission to an IH International Harvester 266, 304, 345, or 392 V8 engine.

Includes adapter plate, torque converter adapter, and installation hardware. You will need a 727 automatic flex plate, crank spacer, and bolts that are found in a 72-80 Scout II and 72-75 Pickup/Travelall for installation of this adapter. 

For 700R4 we suggest to use a truck version of the 700R4. You will need to custom fabricate a flywheel cover or a cover kit can be purchased separately. Transfer case will also need to be swapped to a GM unit or an additional adapter to go from the GM 700R4 to Dana 20 will be required if used in a 4X4 application such as in a Scout. We can also supply you with any transfer case adapter that you might need for this conversion. For those wanting to install in a pick-up or Travelall custom transmission mounts and rear engine mount will need to be fabricated. Please email or call if you have any questions regarding this kit.

4L80E transmissions use 3 of the 6 torque converter bolts like the older Turbo 400's. 

MADE IN THE USA.

Submitted by: Adam Allman (Salem, OR)

I installed this kit with little issue, only issue I ran against was the stock starter drive nose cone had to be ground on to fit. I would buy this kit again, great setup, I used a small block chevy midplate to make rear engine side mounts in my 65 pickup. worked like a charm. Thanks for offering a great upgrade.

I installed a 4l80e in my 1962 C130 4X4. Great kit. Simple installation. Love the 4l80e behind the 392 V8.
