The Edelbrock #8863 big‑block Chevy reverse‑rotation water pump is polished for appearance and intended to prevent overheating in street rods, street machines and tow vehicles using 454ci engines in C/K pickups (1988 and later). It uses racing‑grade passages and a precision powdered‑metal impeller to provide maximum flow and pressure with equal distribution across the block, flowing in one direction for efficiency.
