340 Static Compression Numbers and Test Procedure

Thanks but are you sure the torque converter is what has counter weights and not the flexplate on LA’s? I understand that the flexplates are either externally balanced or neutral and the TC’s are always neutral.

The converters have the weights.

That HB you pulled is for an internally balanced crank. That won't work with an externally balanced crank.

So, with no weights on the converter it's an internally balanced crank.

That can still be a cast crank, but if it is, someone spent way more money on a cast crank than I ever would.
