Cast crankshaft, properly prepped is fine for that application... won't last any less than forged GM crank prepped the same. GM forged cranks aren't made of premo material and I have probably seen more cracked steel ones than cast...Make sure you select a core that has good cheeks on the top of the rod throws and good oil hole placement on the rod & main journals. Important to find a crank grinder that knows what he is doing as far a journal radius and to further enhance the life of your bearings, it helps emencely to have the crank surface hardened \ nitride or equivalent...
