Top Street Performance Short-Style Circle Track High-Flow Mechanical Water Pump for Chevy Small Block - Polished

TSP's high-flow mechanical water pumps provide that extra cooling power your high-performance engine demands. They are lightweight and flow at a rate up to 40% over stock pumps.Lightweight Aluminum Housing All mechanical water pumps from TSP are cast from lightweight A356 aluminum and heat-treated to T6 hardness. This not only provides strength, but aluminum works to manage heat far better than cast iron. They are available in a satin, polished, or chrome finish.High Quality Components From top to bottom, TSP's mechanical pumps are designed for greater performance and reliability. They feature an 8-blade, cast aluminum anti-cavitation impeller. Its 3/4" shaft is driven by heavy-duty bearings and seals, and the crank hub is 1/2" thick for added strength.Compatible with: CHEVROLET SMALL BLOCK V8 GEN.
