Per research, apparently the KF code pulley is a common 3 groove water pump pulley for 455 blocks. It measure 6.125" diameter.

For some reason I spontaneously bought this water pump pulley without knowing it's exact application. The only visible stamp is "KO". The diameter is 5.625" (smaller that the KF).

Anyone know the application for this thing (year, etc)?

72 455 with 6.1" pump I think.
KB crank is the match

 

Thanks for the info.

Another question - Is the pulley worth $20 more or less? It is powdercoated.

 

Is this pulley for sale? I need a 3 groove pulley because i bought a water pump that's too long.

 

Actually, KO is the one that i need. I was just reading your description.

It's for 350 blocks that came with either HD Cooling or Air Conditioning.

Hey Mike,

Still trying to figure out this whole pulley thing. Boy did i mess up when i ordered my water pump.

Was wondering if you could take a measurement for me like you did in your second picture.



Could you measure the total width? I seem to be exactly 1 pulley length off in my current setup.

Thanks!

Hey Tony,

The measurement from the most outside edges is just shy of 3 inches - 2 7/8th (2.875) to be exact. If you need more measurements let me know.
