amc 360

[Jeepfrk9]

Hello all,

I removed and rebuilt a 360 (auto tranny) and going to replace my 304. I just recivied a flywheel from another 360. Were all the 360 flywheels balanced the same or do I have to take my flexplate and flywheel down to the machine shop to have it balanced alike?


Thanks

The amount of static imbalance (starting point) is the same for all 360s.

However, then FINAL balance (done as a rotating assembly) would be different engine-to-engine. The real question is; how far (or how close) to tolerance will your engine be if you put this flywheel on as-is?

If you've done a gnat's-ass blueprint job on this engine, then I would say stop at nothing, spare no expense, and get this flywheel balanced on your rotating assembly. If you've done a 'normal' ring-bearing-gasket-cam-lifters-timing set job, then I would bet that you can run the stick flywheel as is.

If it were mine, I'd throw it on and run it, but I wouldn't be doing a full-boogie blueprint drag-race style build for a Jeep.
