I've got a flywheel that I believe is from an L98. It's definitely for a 1pc rear main, and the GM part number is 14088671. I'm currently building a vortec 5.7, and am wondering if the flywheel will be correctly balanced for this motor. I know they're counterweighted, just don't know if its the same on all 1pc motors. Any help would be appreciated.

86-up 305 and 350 `wheels all interchange. Make sure whether you have a 153 tooth one.
