There Is No Replacement For Displacement.

Starting with a Gen VI four bolt main block, GM fills it with forged pistons, forged 4340 steel connecting rods with 7/16'' bolts, a 1053 forged steel crankshaft and a steel roller camshaft. Then they torque down a pair of big breathing rectangular port heads with 2.19'' intake and 1.88'' exhaust valves. With their 118cc combustion chambers yielding a streetable 8.75 to 1 compression ratio, this engine is ready to thump on readily available pump premium. Then they top it all off with an aluminum dual plane intake manifold and dress the engine with a cast iron water pump, 6 quart oil pan, windage tray, 14'' flexplate and torsional damper. All you need to do is provide a 750 cfm carburetor, HEI ignition system, headers with 2'' x 30'' primaries and low restriction mufflers. Requires an electric fuel pump because the 502 Gen VI block has no mechanical fuel pump boss.
