1963 2 Groove Water Pump Pulley

[Bob H.]

Does someone have the correct part number for the pulley? Thanks in advance.

[David B.]

Check GRP. 1.062 in your parts book. There are a couple double pulleys depending on usage.

Yes, GM #3790356 is the correct waterpump pulley for 250/300 HP without C-60

GM #3770245 is correct for 340/360 HP
