On balancing machine
Crank with bob weights on balancing machine----for internal balance crank assy is balanced without dampner or flywheel
As you can see--there is a pretty good sized rear flange that helps with the balance at the rear--this is a BBC stroker crank that also took one piece of heavy mallory metal in the front counter weight to acheive internal----
.In the left photo you can see the one piece of 1 inch heavy metal in the front counterweight.
