Boss 429?
I am trying to replace a water pump on what I thought was a 460 in a 75 F-250. New water pump did not line up, doing a search with the casting numbers on the original pump (C8SE 8505-E) I found out the pump belongs to a 429 Boss. I know the 429 and 460 block are the same, but I have just bought a cam and headers for the same rig and don’t know if I should change anything or not. The only thing I know for sure about this motor is it’s not the original block for this truck. Are the Boss heads or block special, and what numbers am I looking for to see if it’s more than just the water pump that is a Boss? This one has kind of thrown me for a loop, any advice would be appreciated.

If its a Boss 429 the valve covers will be extremely wide with the spark plugs being located through the valve cover. Its a rare engine as well, I doubt you would find one in a pick up and not know about it before hand.
I didn't do any checking on that part number but are you sure its a 429/460 and not a 360/390? Can you post a pic?

I’m pretty sure it’s a 460, but this water pump has me scratching my head. Plugs are normal, nothing going through the valve covers. I guess it’s possible previous owner put in boss water pump and radiator on this rig. This inlet is on drivers side, normal 460 is on passenger side. Of course Boss 429 water pump is twice as much, welcome to my world!!

The reason for the "shorty"? To save space at the front of the engine. Nothing more.
If you have a 429, it was likely taken from a T-Bird or LTD.

I found out the pump belongs to a 429 Boss and other 1968/69 429/460's...but was not used after 1969.

Numbers, thanks for the help. Number overload, but explains what i have. Problem now is i cant find one. Local Napa, Autozone list it, but nobody seems to be able to order it. Found a local guy to rebuild what i have, a little spendy but hate to start to cut corners now. Thanks again for the help
