Superior Engine Block Construction
Speedmaster Aluminum and Cast Iron Engine Blocks are ideal for street or all-out racing use and styled with an OEM look that works with stock components. With the original water jacket design in place, Speedmaster re-engineered the blocks with extra-thick cylinder walls and decks, super-strong webs, and billet steel 4-bolt main caps to eliminate common factory flaws. Each high-density engine block has enlarged bosses for offset or oversize lifters and is well suited for any 1500+ HP supercharged, turbocharged, or nitrous application.
