Speedmaster PCE195100502 Features:

• Cast with a ribbed aluminum housing which decreases overall weight while keeping the housing integrity intact
• A heavy-duty ball/roller bearing assembly ensures the pump can handle abuse on the street or at the drag strip
• The bigger impeller and larger cavity size flows 40 percent more coolant than stock making this ideal for hotter street engines

Note: Small block chevy engines with a long water pump will have a hub height of 7 inches. If you are unsure, Chevy passenger cars from 1969-1987 (excluding Chevy Corvettes) and Chevy light-duty trucks 1973-1986 typically used this style of water pump.
