im trying to run a mechanical fan on my ls1 . I have an f body pump and truck pump side by side and the housings look identical. Shaft sticks out the exact same. I'm worried if I swap the threaded pulley over to the f body pump it won't go down far enough to line up with the Camaro accessories . I don't want to run truck accessories. I'm trying to keep everything close to engine as I can since space is limited. Electric fan is not an option. It will not work for my application.

Anyone know the part number for the old 98 ls1f body water pumps with bolt on pulley?

As far as I know, only the vettes got the bolt on pulley.
I've got an f body pump with a truck pulley on it in my garage for truck spacing. I'll have a look and see if there's another 3/4" space under it.

It looks like it will bottom out before it reaches the f body spacing.
