Flywheel question help

Will a flywheel from a 4.3 s-10 work on a 350 Chevy engine?

 

To clarify does anyone know if the flywheel off of a 4.3 s-10 will work on a small block Chevy I know they will bolt up its a question of balance

 

Counterwieghts on flywheels are kind of obvious looking wieghts on the flywheel itself.

 

If it's a weighted flywheel from a 1987 or newer, and the engine is also 87 or newer, then yes it will, they use the same weight.

If it's older then it should work also, neither of them use a weight.

The newer ones have a small bolt pattern, older ones are large bolt pattern. Something to do with going to a one piece rear main seal instead of a two piece.
