One of GM's Most Popular Big-Blocks is Elevated with More Power!
With the popular and proven ZZ502 as its starting point, Chevrolet Performance engineers took its capability to the next level to create the more powerful SP502/605 Deluxe, which is rated at a strong 605 hp and 580 lb.-ft. of torque. It’s the sort of power for your vintage muscle car, hot rod or classic truck that comes only from the incomparable Big-Block family.
New, higher-compression pistons, a new hydraulic-roller camshaft, CNC-ported oval-port heads and more drive the SP502/605’s greater output — and this all-new Big-Block crate engine is distinguished with all-new cast aluminum valve covers based on the striking, contemporary design introduced on the ZZ632.
It is offered in a Deluxe kit that includes an 850-cfm carburetor and aluminum intake manifold, HEI distributor, plug wires, starter, water pump and balancer. It also includes a new-design five-quart oil pan.
