Thread: clearance of electric fan on SBC

Tweet

There is a water pump riser that is especially made for the SBC. It raises the water pump and fan up 5 inches, to center the mechanical fan in the radiator. The pump riser is all aluminum. I have one on my SBC in my '32 Ford. The price is kind of steep, around $200, but it works great. You still need to run a fan shroud for the best cooling performance. The pump riser also uses a GM six cylinder water pump instead of the V8 pump. I use the Hi-performance six cylinder pump with no problems.

While the price sounds high, the pump riser also comes with additional brackets to mount the alternator on the drivers side and an AC compressor on the passengers side.
