454 gen 6 block, forged stroker assembly. I just picked up my rotating assembly, i had it balanced as well, after seeing that the flexplate and balancer both have weights on them, i said i was supposed to have this internally balanced and use a 396 neutral balance flexplate and balancer, so in the future i dont have to rebalance if something happens. they told me that the 1pc forged crankshafts can't be balanced without weights on the flexplate and balancer. i found this odd. they took weight out of the crankshaft as well, so i dont see how this could be true. it looks like they gave me an external 454 flexplate and cut the weight off of it, and added weight on it elsewhere so they could balance the assembly, something about this whole thing doesnt seem right. so my question is can a 1pc forged 454 stroker crank be balanced without the balancer and flexplate?
496 balanced kit doesn't look right

some can, some can't or will be an extremely expensive operation. If the crank was originally ordered as an internally balanced deal this usually includes includes longer rods and lighter weight modern pistons. The longer rods allow for larger counterweights and the lighter pistons reduce the amount of counterweight needed to begin with.
If you have an externally balanced setup it can be converted to internal balance, but the shop has to drill out the counterweights and install slugs of heavy metal, AKA Mallory metal. this allows use of non-counterweighted balancer and flywheel.
If you are running a street type engine the benefits of internal balance are largely theoretical, don't lose any sleep over it.
