SP502/605 Deluxe

SKU: 19421200

One of Our 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.

INSTALLATION NOTES • Due to crate fitment, the carburetor is shipped in a separate box and must be installed by the engine installer
• Clutch linkage bosses are drilled and tapped. When using cast iron exhaust manifolds, lower head bolts may need to be replaced with bolts for shorter heads, for clearance

• Comes with an externally balanced 14” automatic transmission flexplate. Use flywheel P/N 14096987 and 11” clutch assembly for manual transmission applications
• Not intended for marine applications
