The ZZ502/502 Deluxe crate engine includes the entire engine, from carb to oil pan, and comes completely assembled from the factory. It includes a Holley 850-cfm four-barrel carburetor, dual-plane water intake manifold CNC-port matched to the oval-port heads, starter, distributor, plug wires, and water pump.

Installation Notes

  • NOTE: Distributor with melonized steel gear MUST be used with long blocks and partial engines with steel camshafts, or engine damage will occur. GMPP distributor P/N 93440806 is recommended.
  • Carburetor and starter not installed because of crate fitment.
  • Clutch linkage boss is cast into block, but must be drilled and tapped. When using cast iron exhaust manifolds, lower head bolts may need to be replaced with bolts with shorter heads, for clearance.
  • Requires electric fuel pump because Gen VI block has no mechanical pump boss
  • Comes with a 14" automatic transmission flexplate.
  • Intended for pre-1977 street vehicles or all off-road vehicles.
  • Not intended for marine applications.
