    INSTALLATION NOTES:
  • Clutch linkage bosses are now drilled and tapped. When using cast-iron exhaust manifolds, lower head bolts may need to be replaced with bolts with shorter heads for clearance

  • Comes with an externally balanced 14'' automatic transmission flexplate. Use flywheel P/N 809-14096987 and 11" clutch assembly for manual transmission applications
  • Designed for pre-1976 street vehicles or any off-road vehicle
  • Not intended for marine applications
  • For long blocks and partial engines with steel camshafts, a distributor with a melonized steel gear must be used or engine damage will occur. Distributor #809-93440806 is recommended.

    The DIY Foundation for Big Torque!

    Free Shipping!

    It's simple: The ZZ502/502 Base crate engine is offered for builders who want the super-strong bottom end and high-flow aluminum oval-port cylinder heads, but also want to finish your engine, your way.

    The ZZ502/502 Base engine uses our new cylinder block casting that is stronger and better suited to high-performance combinations. A forged steel crankshaft, forged rods, and forged pistons form the reciprocating assembly, with a smooth-operating hydraulic roller camshaft delivering big 0.527/0.544-inch lift. The lightweight aluminum heads boast 110-cc combustion chambers and big, 2.25-inch intake and 1.88-inch exhaust valves.

    Chevrolet rates the ZZ502/502 Base engine at 508 horsepower and 580 lb-ft of torque when it is finished with Chevrolet Performance aluminum intake manifold (P/N 809-12363406) and Holley 870-cfm carburetor (P/N 809-19170094). The other parts you need to complete the engine - including chrome dress-up parts can be found here at JEGS.com or give one of our JEGS technical specialist a call at 1-800-345-4545, 24/7!
