88926225 $40 L31 water pump cast iron impeller
12532528 $146 L31 water pump with stamped steel impeller
Both of these are for the 96-99 L31 350 and are Ac Delco parts. Why is the cast iron impeller $100 less expensive than the stamped steel impeller?
I havent bought a waterpump for a while now, but $40 is tough to beat for a Delco pump.
