Thanks.

I have never seen prints nor have I seen evidence that Ford manufactured a counterweighted production crankshaft.
I recall seeing a crankshaft many years ago (-like when I was in my preteen years) that was said to be an old CW crankshaft. I can remember dad & I discussing it years later and our speculation was that it was a B crank that had the journals ground to A sizes.
As with any crankshaft, initially see if passes the ring test. Next mic the journal sizes to make sure it can be used. Then have it 'wet-magged' to check for cracks.
In all of this, consider your overall investment and determine if using an old crankshaft is prudent. In the grand scheme of things, a SCAT crankshaft is not that much more than a Burlington, and SCAT will stand behind their products. Likely because the machine work and the Q/C are done here stateside. Likewise, I have experienced two engine failures with a Burlington crankshaft due to the Burlington journals not properly heat treated. I was 'on my own' with both of those as there is no warranty expressed or implied with that crank. For that reason alone, I will never install another Burlington crank.
