Note: This is a future product that is not available as of yet, contact us at 847-276-8110 for details
Chevrolet Performance engineers took the SP502 capability to the next level using port fuel injection to create the more powerful SP502/605 EFI Deluxe.
It's the sort of power for your vintage muscle car, hot rode 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.
This EFI Big-Block crate engine is distinguished with an all-new port fuel injection intake manifold complemented with the 502-cast aluminum valve covers like its carbureted sibling. Our Deluxe package comes complete from the oil pan to the air cleaner, as well as a crank-trigger ignition system with coil-near-plug ignition coils mounted on the intake manifold, plug wires, balancer and aluminum single plane intake manifold. It also includes a new-design eight-quart oil pan.
