So I am going to bring my crank, pistons, rings, and rods to the machine shop for balancing. I do not have an extra flywheel, the guy at the shop asked if we have an internally balanced engine, or if there is weights on the flywheel.
If there are weights on the flywheel he needs me to bring him one too, anyone know if we have internally balanced engines?

I think it is, so no need to bring the flywheel in


HP Tuners | Garrett T3/T04B | 2.5" Charge Pipes | 2.5" Downpipe | 650 Injectors | HO Manifold | Addco front/rear | Motor Mounts | HKS SSQV | Spec stage 3 | AEM UEGO Wideband | Team Green LSD | FMIC | 2.3 cams | 2.3 oil pump swap | 280WHP | Now ECOTECED

It is internally balanced
All GM 4cyls since like 1977 have been internal.

The flywheel is zero balanced.
