Chrysler Water Pump Cast

The TUFF-STUFF Chrysler Water Pump Cast (1465NA) is a high-volume, mechanical water pump designed for Small Block Mopar applications requiring superior cooling performance. This aluminum cast pump delivers the enhanced flow rates needed for engine builders and hot rodders working with classic Chrysler platforms, making it an essential upgrade for vehicles running extended cooling demands under sustained performance conditions.

Cast in natural aluminum, this Supercool pump maximizes coolant circulation through the engine block and radiator, reducing heat rejection time and maintaining optimal operating temperatures during high-load scenarios. The high-volume design increases GPM delivery compared to stock units, a critical consideration for modified engines with larger displacement, higher compression ratios, or performance cam profiles that generate additional combustion heat. The mechanical belt-drive design integrates directly with standard Small Block Mopar engine configurations without requiring adapter plates or modified mounting brackets.

This pump suits engine builders preparing Small Block Mopar platforms for street, strip, or vintage racing duty. Whether upgrading a classic Dodge, Plymouth, or Chrysler muscle car or modernizing cooling in a restoration project, the Supercool high-volume design provides the thermal capacity needed to prevent overheating when factory cooling systems fall short. Weighing 6.85 lbs and engineered to OEM Small Block specifications, this casting delivers proven reliability without exotic materials or proprietary fitments.
