66-69 Pontiac 350/400 Water Pump 8 Bolt

The 66-69 Pontiac 350/400 Water Pump 8 Bolt by TUFF-STUFF is a precision-engineered mechanical cooling system component designed for classic Pontiac V8 engine blocks from the mid-to-late 1960s. Built for builders and restorers working with 350 and 400 cubic-inch displacement engines, this water pump maintains consistent coolant circulation under sustained load conditions. Whether you're completing a frame-off restoration or upgrading a stock cooling system, this pump delivers reliable thermal management that keeps your engine operating within optimal temperature parameters.

Constructed from durable cast iron with a natural finish, the 66-69 Pontiac 350/400 Water Pump features an eight-bolt mounting pattern that secures directly to your engine block without adapter plates or modification. The mechanical design relies on a sealed bearing assembly and impeller geometry optimized for V8 coolant flow rates, ensuring efficient heat dissipation across high-performance and stock operating conditions alike. At 8.96 lbs, the pump's mass reflects solid iron construction—a hallmark of longevity and thermal stability in vintage engine cooling systems.

Restorers and engine builders working with 1966–1969 Pontiac V8 platforms will find this water pump essential for any cooling system rebuild or modern performance upgrade. Installation requires no modification to factory engine bay components; the eight-bolt pattern ensures drop-in fitment on compatible 350 and 400 block castings. Pair this pump with quality hoses, a period-correct or modern radiator, and a reliable thermostat to establish a maintenance-free cooling system capable of supporting both cruising and sustained throttle applications.
