What flywheel do I need????

[68383GTS]

If I put a 4 speed behind a smallbock with a cast crank what flywheel do I need to use???? All the ones in Summit say for neutral internal balance.And a cast crank is external balanced.

Thanks,Jim

Which small block Jim? I ask because cast crank LA 318's are internally balanced while cast crank 340's and 360's are externally balanced.
