Product Details

Features

  • Chrome mechanical fuel pump for Chevy Big Block Mark IV V8 (396–454)
  • 80 GPH flow, 6 PSI pressure — no electric pump or wiring required
  • Requires a 5.75" fuel pump pushrod for proper BBC operation

Description

Built for carbureted Chevy Big Block V8 (Mark IV) applications, this mechanical fuel pump supports dependable fuel delivery with a clean, chrome-finished engine bay appearance. Its 80 GPH flow rating and 6 PSI operating pressure make it a practical replacement or upgrade for engines using the correct mechanical pump mounting pattern.

As a mechanical pump, it draws its pumping action directly from the engine's camshaft via a pushrod — no electric pump, wiring, or power source is needed. This unit requires a 5.75" fuel pump pushrod for proper operation on Big Block Chevy engines. Confirm pump arm style, gasket placement, and line clearance before installation.

This pump is designed for carbureted fuel systems and is not intended for EFI applications unless used with a properly designed and regulated fuel system conversion.


Applications
Fits Chevrolet Big Block V8 Gen. II (Mark IV) engines — 396, 402, 427, and 454 CID — commonly found in Camaro, Chevelle, Corvette, C/K trucks, and full-size Chevrolet applications using Big Block power.

Installation
Requires a 5.75" fuel pump pushrod for correct operation on Big Block Chevy engines. Verify mounting pattern, pump arm style, inlet/outlet orientation, and pressure requirements before installation. Mounting hardware is not included.
