I called TSP and they dont know the numbers on this crank.

according to my yahoo search, your crank is a 10 foot sheet of extruded aluminum formed in a special shape, manufactured by Lockheed Martin.

other than that, i have no idea.

try calling Callies, Eagle, Scat...etc.

they might not know either because it may be a casting number having nothing to do with the company that ground it. most crankshafts are forged by a common foundry and are sold to various companies to be ground to different strokes...etc.
