i read that the flywheel is the same for 390's and 429's as long as they are before they externally balanced them (late 70's). I am looking for a 429 flywheel, and the slavage yard by me has several late 60's early 70's 391 truck motors with a flywheel on them.. For those not familiar, the 391 is virtually identical to the 390.. Does anyone know if this flywheel will work?

Can you just cut the weight off of the flywheel? I have removed weights before for rebalancing. Is the 391 flywheel wiht the wieght removed useable?
