F0415ccd is what's stamped by the distributor. I'm going to try the Google machine to see what that means.
My other 46 (2ton) I got as a project from a guy that got in over his head, mounted the motor and left everything else incomplete. That's got a 235 and the water pump is VERY low on the radiator, with no fan installed because it would hit the lower radiator hose. I think I've got that one sorted out (relocation bracket for the water pump) but wil need to take some measurements to see where the 250 water pump will land.
I am definitely trying to avoid an electric fan!
All this while building a house for my family so my progress is way slower than I want!
