Crate Engine ZZ502/502 Deluxe Engine Kit Highlights: HP: 502 @5200 rpm TQ: 567 @4200 rpm Gen VI iron block with 4-bolt mains Aluminum oval-port cylinder heads Dual-plane intake manifold CNC-port matched to oval-port heads High-lift roller camshaft 6-quart oil pan with windage tray HEI distributor and 8-mm plug wires Build-it yourself version of GMPP's powerful 502-horse rat. When it comes to horsepower and torque, it's hard to beat GMPP's popular ZZ502/502. With 502 horses and 567 grin-inducing lb.-ft. of torque, it's one of the best big-block performance values around. With GMPP's complete engine kit, you can build your own ZZ502 and save. The ZZ502/502 uses aluminum big-valve, oval-port heads which flow tremendous amounts of air to satisfy the demands of the 4.47-inch bores and 4.00-inch-stroke crankshaft. Forged reciprocating components ensure high-performance durability and longevity. GMPP's complete engine kit comes with everything you need to build a ZZ502/502 to the same specs as our crate engine version. The kit comes with a pre-assembled partial engine, including the reciprocating assembly, camshaft, timing cover, balancer and oil pan. Also supplied in the kit for final assembly are the cylinder heads, valvetrain, intake manifold, 750-cfm four-barrel carburetor, valve covers, water pump, HEI distributor, spark plug wires and fasteners. Installation Notes: 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 bolt with shorter heads, for clearance. Requires electric fuel pump because Gen VI block has no mechanical pump boss. Comes with a 14-inch automatic transmission flexplate. Not intended for marine applications.
