Im gonna go ahead and buy myself a new flywheel for my swap, but i dont have a clue which one to buy. I know i need one for an 81-later mustang, but i have no clue what 50oz./28oz./0oz.in unbalance means, my engine is stock so can you guys help me out? O ya its just gonna be a street car for now so im not looking to get anything overly expensive/fancy, keeping it simple.By the way, WTF does all that unbalance krap mean?
