340 Static Compression Numbers and Test Procedure

Well rather depressed as I tried and one last method to determine if this crank is cast or not. I tried using my bore scope up into the oil pan. While a great idea the windage tray makes it very difficult and there is enough residual oil to foul up The camera tip...... Now I know how the GI doctor feels after a bad colonoscopy .....

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.
