4x4Freak is partially correct, but you can have an aftermarket balancer or flexplate/flywheel with those same descriptions, and then there were some small block that were balanced just as the 400's were. Casting numbers are the best bet.
If you have access to the side of the block look for one that is stamped with "509". These blocks have a higher nickel content.
If and when you get a 400, start by throwing the heads away.smokin
