SB/BB Chrysler F/P Block

The SB/BB Chrysler F/P Block from HOLLEY is a precision fuel pump mounting block engineered for classic and vintage Chrysler small-block and big-block engines. This compact adapter serves as a critical interface component for fuel system installation, enabling reliable fuel delivery on both street and competition builds. Whether you're restoring a muscle car, building a restomod, or maintaining existing fuel system infrastructure, this mounting block ensures secure, leak-free fuel pump positioning without modification to original engine architecture.

Manufactured by HOLLEY, a trusted name in fuel system components for over 100 years, this block is precision-machined to OEM specifications and tolerances. The compact design (5 × 1.75 × 6.95 inches) integrates seamlessly with standard Chrysler engine block configurations, providing a robust mounting surface that distributes pump pressure evenly and reduces vibration-induced wear. At just 0.18 pounds, the block maintains minimal parasitic weight while delivering maximum structural integrity—critical for engines where every ounce matters and fuel system stability directly impacts performance and longevity.

Technicians, restoration specialists, and performance builders depend on this block for Chrysler engine platforms spanning small-block (318, 340, 360) and big-block (383, 400, 426, 440) applications. Installation is straightforward: secure the block to the engine with supplied fastening points, then mount your fuel pump to the block's flat surface using the provided or standard hardware. Compatibility extends across decades of Chrysler production, making this block an essential inventory item for shops supporting vintage and modern muscle car projects. Confirm your specific engine displacement and fuel pump type before ordering to ensure optimal fitment and function.
