AOD swap question

I've got an 86 F150 1/2 TON 4X2 with a 302 / AOD.

I found a 90 F150 1/2 ton 4x2 with a 300 6cyl 5 speed.

I'd like to swap my AOD for the 5 speed...

Besides the obvious (pedal / slave cyl etc) what issues should I expect?

Will the 90 model flywheel bolt up to my crank?

Does it matter which starter / drive shaft / tranny mounts I use?

Thanks in advance!

I'm not sure about starters, but you will need a post-81 302 flywheel.
Until 81 they used a 28oz balance, 81-on was 50oz.

The 6cyl flywheel is a different balance to either of the 302 flywheels.

Also, the pedal bracket from 87-on, is different to the 80-86 version.
I think when the later one has been 'made' to fit, the result hasn't been very satisfactory.

Very important issue: You CANNOT swap flywheels or flexplates between a 300 and a 302. They will physically swap - they have the same hub size and bolt pattern. The 300 is internally balanced and has no counterweight on the flywheel/flexplate. The 302 is externally balanced and has a counterweight on the flywheel/flexplate.

You will also need to figure out the TV cable at the throttle. Without it you will burn it up in no time.

Cool, I'll order a flywheel / clutch combo for the 86 - 302. The splines will be the same, right?

I think he's talking about going from an AOD to the 5 speed so the TV cable isn't needed.
