anybody run this Speedmaster crank?

I was wondering if anyone had insight to the quality on the Speedmaster cast 3.85" crank? Here is an Ebay ad:

Looking at a mild build at 600hp and not happy with the Internal balance cranks I'm finding at .020" or .030"

I got a good stock crank out of a 86 motor home it is standard on mains and rods with new king bearings for it I was going to use it but didn't need it I will take $150 plus shipping for crank and bearings. PM me if you are interested I can take pics and text them to you.

There is nothing wrong with an OEM 460 crankshaft that is 0.020"-0.030" undersize, as the journals will be machined and polished to as new, and there can be plenty of good bearing options at those undersizes for a 600 hp engine (or double that power level which such OEM 460 crankshafts have been known to handle). And I'd take a used OEM nodular iron crankshaft over that offshore scrap metal crankshaft any day of the week...or month...or year...or lifetime.
