OOOOPS...!!! 454 flywheel.. wrong part???

454 flywheels do have balancing weights on them right?

I just discovered that my engine is running with a regular non balanced 350 flywheel, but I haven't noticed any strange vibrations.

my engine comes from a 1984 C30 pickup, did this engine come from the factory with a balanced flywheel? are all 454's externally balanced?

the previous owner must have changed it and didn't noticed the difference.

I'm doing a cam swap and some minor porting before it goes into the engine bay of a '46 chevy, will bolt to a modified TH350 with a 2.200rpm converter and 4.11 rear end.
