does anyone know the original casting numbers on a 86-87 3.8 turbo crankshaft?

You can't identify an N/A crank from a Turbo crank by the casting # alone. They share the same casting but the Turbo crankshafts have rolled fillets on the main and rod journals.

229


but like Neal said, it's possible to have a 229 that's final machined for a N/A application
