I've heard that those early Eagle 'blems' that came .010/.010 were pretty good cranks. They got re-ground locally because they arrived at Eagle with taper on the journals.

I bought a 4.25" B-motor crank from the Sourcerers; (had taper which Brandon paid to have corrected, and was wide on the thrust, which had to be ground .010 wider). I don't recall the weight; I paid for the pendulum-cut counterweights and scalloped flange.

Apart from the finish machining on the journals, it didn't look like a bad piece.

I can't remember what the bobweight was on the balance ticket; think it was around 1750-1800 grams (all Source parts), so I'd expect that it would balance easy enough if you don't have heavy pistons.
