1963 Chevy Impala Z-11 Old Reliable. A Total of 57 were Produced.

Under the hood was a revised W-series engine. The stroke was increased from the 409 by .150-inch using a forged-steel 3.65-inch stroke crank to make it a 427, while the bore remained at 4.3125 inches. Forged connecting rods were employed, and forged domed pistons pushed the compression ratio to 13.5:1. High-port cylinder heads with 2.19/1.72-inch valves, a cam with 325-degrees duration and .556-inch lift and a high-port two-piece (separate valley pan) aluminum intake were used, as was a pair of Carter AFB carbs. Factory-designed cast-iron headers were installed, but were generally quickly swapped out for steel-tube headers. The aluminum water pump, fuel pump, lines and filter and the rocker covers were also specific to this engine, and a deep sump oil pan was used. The 427 was underrated at 430 hp, some say it could be tuned make over 600 H.P.
