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.

Stand the crank up on end and grab a hammer and smack the end of the crank snout pretty good and see if you get a good "ping/ring" sound out of it?

I already had it machined for the rebuild. The shop said it is a very high quality forged stroker crank.
Im going to look to see if tree are markings he missed
