340 Static Compression Numbers and Test Procedure

I seriously doubt anyone would be silly enough to internally balance an OE cast crank. I know I probably wouldn't do it, even if the customer wanted it.

It would be an incredible waste of money. I can find better places to spend money than to internally balance a crank like that, especially if they already had a damper and torque converter.

But, I've been doing this long enough to know that stranger things happen. But I doubt this is a cast crank.

BTW, back in the day I've seen engines balanced with a weighted damper on the front just for the claimed better dampening characteristics.
Hey YR I don’t think I am implying that this is a balanced cast crank as I have no clue as to what it is. I agree a balance job on a cast unit makes no sense and I doubt any machine shop would even do this.
Just trying to figure out how best to continue if I don’t know what it is. The previous guy who worked on this set up had no brains whatsoever so I am not convinced that it was set up correctly. I guess I have to pull the oil pan to get a better look at the crank to make a determination if its forged (internally balanced) or cast (externally balanced).
