Description

This Short block kit utilizes the later model 400 block (557 casting) in stock stroke (as not to overstress the block) with forged pistons and eagle crank. This kit is a great foundation for a complete engine build capable of up to 475 hp on pump gas. Top it off with a good set of cast iron or Edelbrock heads for a strong and powerful muscle car engine.
