Search didn't answer my question, and I can't be the first to run into this so..... I swapped in a serpentine belt system from a GM vehicle on my SBC and wanted to go to an electric fan. The snout on the water pump hits the electric cooling fan. A short water pump (90 Corvette) gives me 3/4" clearance but I need a pulley to allow the belt to run close to the end of the pump for allignment. I don't want to swap everything over to the Corvette brackets and pulleys due to cost. I cant be the first one to run into clearance problems with a water pump so please help. The best I can do right now is to modify a Ford 4.6 pulley to fit the Corvette pump.

 

ah, so you have a 1990 Corvette, and not a 3rd gen Camaro at all eh?
Why not go ask on a Corvette forum then? anethesis probably knows a good one.
Short pumps are rare, I don't think you'll find anyone here using one. I'm using a long water pump, and an electric fan, and in my CAMARO it fits fine.
Using a short water pump (I assume) would mean you need the rest of the bracketry to match up. Truck brackets might work, or other parts from the '60s.
Good luck though, I don't *think* what you're doing is that common (on this forum at least, hence why I suggested a 'vette forum).

 

Uh, I believe he was only talking about the water pump with regard to Vettes.

 

You caught me, it's a serpentine install on a 400 sbc with truck brackets and electric fan in a Jeep. I am also doing a 454 TBI at the same time and found alot of good info on this board so I thought I'd see if anyone had used a Corvette short pump here and ran into the same problem.
Short version is: no such pulley exists in unmodified form for what I am doing. Most people who run a short pump, also run all of the short brackets and accessories. I called ASP Racing down in Texas and he is machining a steel pulley to my demensions, he has done this in the past for people with my problem.

 

Late '60s and early '70s pickup trucks used the short pump as well, if I remember correctly. Maybe that will help you find what you need??

 

Nope, 60's and 70's wont work because the whole point of doing the upgrade is to get the serpentine belt system. Thanks anyway.
