Hello - I need to replace my water pump. I was told I need the casting number from the pump but the truck is my daily driver so i cant take it apart and have the vehicle down for days. I was told the engine is a 261 (in a 52 suburban truck) I found two engine vins on the block by the distributor - F0507XTA and CEO 14363. I cant seem to find out what engine i really have from these vins. If I know for certain what the engine is i am hoping i can call a place that knows enough about the trucks to get me the correct part i need. Any help here is appreciated. Thank you
