LS PA Short Block

+

This LS Power Adder Short Block comes standard with a DART SHP Iron engine block. This block utilizes a 6 bolt cylinder head pattern for extra clamping force to help secure the cylinder heads and head gaskets. It also has billet steel main caps with splayed outer bolts. This greatly increases the strength of the engine block and tightly secures the crankshaft. Please call for additional options or upgrades.
