SBC Water Pump Riser to clear dual puller fans ?

[Smiley]

Speedway sells these for old street rods like the 32 Ford with a small block Chevy motor, it raises the water pump pulley 5" to allow a larger mechanical fan to be centered in those tall radiators. It takes an L6 Chevy water pump and uses stock short small block V8 pulleys. L6 pumps can be had in aluminum or cast iron, aluminum being the HD version with the price almost double the cast iron pumps.

It looks like it might work on an H-body for those wanting to use larger dual electric puller fans without moving the radiator into the core support.



The long input shaft would allow the flange to be pressed on farther to gain another 3/4" or so, then use a dual groove pulley and cut the rear groove off.


quick mock up with 21" core rad, two 10 1/4" plates and pump pulley 5" above where the fan is normally.

It also has an alternator mount provision close to the Monza location. It is a little pricey at $250 + the L6 pump.
I have not tried it yet, but I have returned things to Speedway in the past without hassles.
