Flywheel question

Question:

Will a flywheel off of a 327 / muncie 4 speed bolt up to a 454 / 700R4? I.e. is there a difference between a flywheel for a manual trans and one for an automatic?

Re: Flywheel question

Two completely different animals. A manual uses a flywheel. A slushbox uses a flexplate.

Re: Flywheel question

On top of the flexplate/flywheel issue one motor is internally balanced the other is externally balanced

Re: Flywheel question

You need to buy one for the 454 because it is externally balanced. Make sure that when you get it it has the external weight on it. I have seen them package wrong.
