Comp. Alm. Water Pump 55-95 SBC Short

The PRW Industries Comp. Alm. Water Pump 55-95 SBC Short is a high-performance mechanical water pump engineered for Small Block Chevy engines demanding superior cooling efficiency. This pump is purpose-built for enthusiasts and engine builders who require reliable, consistent coolant circulation during aggressive driving, street performance applications, or modified engine builds. The short design makes it ideal for tight engine compartments where space constraints eliminate standard-length pump options, while maintaining the flow rates necessary to prevent overheating under sustained load.

Constructed from lightweight aluminum with a black ceramic coating, this water pump combines durability with corrosion resistance—critical for longevity in both street and race environments. The revised impeller entry design optimizes coolant flow dynamics, reducing turbulence and cavitation while maximizing pump efficiency across the entire RPM range. The 3/4-inch pilot mounting interface ensures precise alignment with SBC engine blocks and compatible brackets, delivering dependable performance whether running stock displacement or upgraded engine packages through 1995 models.

Mechanics and engine builders favor this pump for restoration projects, engine swaps, and high-output modifications where OEM cooling systems fall short. Its compact footprint makes it essential for custom-fitted engine bays, fuel-injected conversions, and tight installations where clearance is limited. Direct fitment across 1955–1995 Small Block Chevy platforms—from the classic 283 through modern 350 variants—ensures broad compatibility while delivering the thermal management needed for reliable operation during track days, weekend cruising, or daily-driven performance vehicles.
