Question about Cars & Trucks
You would have to get the foundry bill of material for that crankshaft
finding the casting foundry will be a job in itself
however crank shafts are cast to a engineering standard (throw distance) and are then ground to a standard size on the big ends and main journals
what ever con rods that are used depends on the block that the crank shaft is installed in as different piston diameters require different strength conrods
the casting number is just a batch number so it may prove a dead end if you are relying on it to get information
where I would start looking is at a engineering shop that regrinds crank shafts as they may have original specs for gm cranks and that number just may indicate what block it was made for and then you may get a heading as to where to look
