One of the inherent problems of a small block Chevy engine swap into any early car is the stock Chevy water pump is mounted too low for the mechanical fan to be efficient. This cast aluminum water pump riser solves the problem by raising the pump and mechanical fan 5" higher in the engine compartment. The housing also provides mounting surfaces for an A/C compressor and alternator. The riser housing (A) comes with brackets and hardware while the water pump (B) is not included.
