Dom, I know it matters about the heads. I'm using 2.5 heads on the 3L shortblock. If the 2000, having the same part number as the 2001, has the water pump on the front end, then I need to use and electric water pump. I want to use the mechanical drive water pump with the 2.5 heads.



SETour95, I think you are confused... Or are you just confusing us???

Any year 3L block from '98+ can be used with the 2.5 heads and the factory 2.5L water pump mounted on the left bank cylinder head. This is what's known within our community as a hybrid swap. No electric pump needed.

The electric pumps only come into play if you're using the 3L heads from '98-'00 as a full 3L swap and has nothing to do with your hybrid 3L plans. Or, if you wanted every last bit of HP and you can swap out the factory water pump anyway for the electric one.
