crazydave1978 · Feb 20, 2006

does anyone know if a 390 manual flywheel will work on a 460 seeing as how they are in the same family anyone that can let me know the info is much appreciated

If I remember right the 360 and 390 are in the same family but not in the same family as the 460. But then again I'm no expert. If it bolts up correctly I would try it. Being sure it didn't interfere with the starter and such.

the only thing im worried about is how its balanced i was told that the 351m and 460 flywheels are the same except how they are balanced thats why they wont interchange

I don't think that anything from the FE blocks will work on the 460. Ford had two types of big blocks back in the late 60 and 70s. the 360,390,427,428 were all Fe blocks, and the 429,460 were different, I believe they were classified as svo. Pretty much anything Fe is devoted only to Fe's, its more than just being able to bolt the flywheel up and balancing it to your engine, any tranny that will bolt to the 460 won't be able to bolt up to an Fe, so the shaft comming out of the tranny probably won't fit into the pilot bearing, or it would be a different length or something. anyway hope this helps, gives you something else to check when your looking at the flywheel

this guy has it right! 460 stuff doesnt play well with others. get the right year of 460 flywheel also.if you dont it will shake out your filling or brake your crank. or both! hillbilly.

sorry to disappoint you guys,BUT in tn we have always used the FE manual flywheel in ALL 460 swaps.It is the same as the 460 only its an fe-no shaking or sour feeling of being lied to.It was always a standard of mine to use a heavy duty clutch and a ROLLER pilot bearing instead of the bushing.It is so simple,but somuch more effective.In the case of buying a clutch from a store or catalog-when asked it is for a 360,390,428 motor.I hope this puts all uneasy feelings to rest.

The FE flywheels will work on the 429-460 up until 1979, they changed the balance setup then.

I put a 390 down in my 78 bronco and used the bronco 4 speed transmission. Before I tried it. I measured the shaft and everything measured up.Even the pilot bearing,but as you stated. The 429 and 460 is a different family from the fe--390 family.
