Thread: Flywheel question

Tweet

I currently have a FMX transmission behind a 302 in a 1976 F100.

I intend to swap to an AOD for a variety of reasons (aftermarket support, higher horsepower builds, overdrive, lockup convertor, etc).

Looking through my data, it seems that with this truck of this time period the FMX and c5 shared a flywheel, the AOD and c5 also shared a flywheel.

So I guess what I'm asking (in a roundabout way), does anyone know if I can use the FMX flywheel on the AOD?

thanks,
Drew

From Grade 10 algebra----"If A=B and B=C, then A=C".
But maybe Ford flunked grade 10.

Woulkd that be a yes or no ?

The only way to know for sure is to take 'er apart and try it, but I think your 'wheel will work. 302's are balanced by the flywheel weights and there are different ones, you want to keep the original if at all possible.

yessir Mr Pope, I kinda sorta came to the same conclusion.
I'm new to these little engines, figured I'd throw out the question anyway... Typically someone out there has walked the same road as you sometimes, they often have a lil extra knowledge.

thanks,

Fords are the most frustrating engines to work on, but they do respond to mods well. It seems that every bolt on them has to go back in exactly the same hole it came out of, especially on the front cover. And there's always one more bolt that you missed!
"Detroit" balancing is a pain, and there was a starter/ ring gear change in about '82 that can make some very expensive noises if you get the wrong combination of parts.
Once you get 'em figured out, though, they're a pretty good engine. I prefer the 351W, but a 302 will sure rev!
