Can I use any AMC V8 flywheel on any AMC V8 engine, and for any year?
The AMC V8’s share a great number of parts between the different engines (290, 304, 343, 360, 390, and 401s) but some items are motor specific. The flywheels are externally balanced for each engine and should not be swapped between the different engines. Baseline 4×4 Outfitters sells the flywheels for the 1971 and up AMC 360 V8 (16912.08) and the 1971 and up 401 V8 (16912.09) These flywheels will not fit any other engines produced before 1971 (different crank flange design) and should not be used on the smaller 304 V8 engine.
