Now there's an option to satisfy those of us who like to Super-Size! GM Performance Parts offers the ZZ502/502, an engine that's not just bigger, but BETTER than the competition.. As the name implies, it features a gargantuan five-hundred-and-two cubic inches of displacement. The 502 is GM Performance Parts' "Rat" motor, which delivers one HP per cubic inch-- a standard that has long been the mark of a great engine. The ZZ502/502 is tested by GM Performance Parts at the factory and is validated as having no less than 502 horsepower and 567 lb/ft of torque.
The ZZ502 comes with GM Performance Parts' aluminum oval-port, big valve street heads that flow enough air to satisfy the hungry 4.47" bores and 4.00"-stroke crankshaft. These aluminum, oval port cylinder heads have generous 110cc combustion chambers and its big-time valvetrain features 2.25" intake and 1.88" exhaust valves to keep your 502 breathing freely! It also features a forged-steel crankshaft and is paired with a hydraulic-roller camshaft for over 500 hp of outstanding performance, all while running on pump gas.
Better still, this 502-cid powerhouse is virtually ready to go right out of the box. The crate includes the entire engine, which comes with virtually everything already assembled. It comes with everything you need from carb to oil pan. It includes an 870-cfm Holley four barrel carburetor, dual plane intake manifold that has been CNC-port matched to the oval port heads, starter, distributor, plug wires, plugs and a water pump. GM Performance Parts Deluxe engines are essentially ready to fire up, as they ship with their ignition system installed, harmonic balancer bolted on and fuel delivery system (carburetor) already right there in the crate. All you need to do is put the parts together!Specifications:
