Chevrolet Performance ZZ502 C.I.D. Deluxe Long Block Crate Engines

Here, at last, is the king of all big block crate engines from Chevrolet Performance. These 502 cu. in. engines are available unassembled or fully assembled. Each version makes extensive use of aluminum to keep weight down—including aluminum heads, intake, water pump, and valve covers. Additionally, ZZ502 c.i.d. deluxe long block crate engines are full of heavy-duty parts, such as: forged aluminum pistons, forged shot-peened steel connecting rods with 7/16 in. bolts, forged steel crankshaft, 14 in. automatic transmission flexplate, 4-bolt main blocks, stainless steel valves, 6 qt. oil pan, and windage trays.

The complete Chevrolet Performance engine kits come with Gen 6 four-bolt main blocks with one-piece rear main seals. Hydraulic roller camshaft specs are: .527 in. intake lift, .544 in. exhaust lift; the duration at .050 in. for intake is 224, and 234 for exhaust with a 112-degree lobe centerline. Other features include a single roller timing chain, aluminum large oval port, and 110cc combustion chambered heads. Intake runner volume is 290cc; stainless steel valves are installed, with 2.25 in. intake side and 1.88 in. on the exhaust side. Valve springs are rated at 140 lbs. closed and 368 lbs. open, good for up to .680 in. lift. These heads have exhaust crossovers. Aluminum high-rise dual-plane square bore bolt pattern intake manifolds and an 870 cfm carburetor are also included.
