look on 440source and read the info on dampers. that will let you ID what/yr dampers you have.

with a 74 you may have the correct one on hand.

what is the 440 engine out of?

MH 440s got steel cranks/6-pac crank/heavy rods/cast crank/LY rods

either internal or external balance depending on which crank rod combo

could you post up some more pics as you go? I am interested and thinking a missing damper outer ring also.

seems I have seen a ferd engine with a hub and pulley only and no damper but thought Humm..must be a ferd thing.
