Starter/Flywheel combo?

i got the Quarter Master combo kit from a team selling out, Starter, Bellhousining and pump mount. How do i know which flywheel I need for this. Its a Chevy

Is your motor internally or externally balanced? That will tell you

Quartermaster will have it's own specific flywheel if your bell has no idler gear a brinn or bert flywheel will not work.
