The Water Pump Back Plate Late Model SBF from ALLSTAR PERFORMANCE is an essential internal engine component designed for small-block Ford engine builders and enthusiasts seeking reliable cooling system integrity. This back plate serves as the critical interface between the water pump assembly and the engine block, preventing coolant leakage and maintaining proper system pressure during high-performance operation. Whether you're rebuilding a street engine, upgrading to modern cooling efficiency, or replacing a worn factory component, this back plate delivers the precision fit and durability that serious mechanics demand.
Engineered specifically for late-model small-block Ford applications, this back plate features precision machining to exact OEM specifications, ensuring a leak-free seal when properly installed with appropriate gasket material. The compact design—measuring 8.2 x 8.65 inches with minimal 1.05-inch depth—integrates seamlessly into tight engine bay configurations without interfering with accessory drives or serpentine belt routing. At just 1.01 pounds, the back plate contributes minimal mass while providing the structural rigidity needed to contain coolant pressure and support water pump mounting hardware. ALLSTAR PERFORMANCE's manufacturing standards guarantee dimensional accuracy and surface finish quality that eliminates installation hassles and potential mid-project complications.
Engine builders, restoration specialists, and performance shops routinely specify this water pump back plate for complete cooling system overhauls and engine swaps involving late-model SBF platforms. Proper installation requires fresh gasket material and careful torque sequencing to prevent coolant weeping at the block interface—a critical step that prevents overheating failures during dyno testing or extended highway driving. This component is indispensable for anyone serious about long-term engine reliability, whether transitioning from original equipment or upgrading to modern aluminum water pump assemblies that demand precision sealing surfaces.
