Always? No! How old are you, s0n?

The 427 FE engine was introduced in 1963 to handle the demands of NASCAR, NHRA, and AHRA, as well as street racing enthusiasts. The 427 block was cast from high nickle content iron with a thickened deck to handle the increased higher compression pressures. The design included mechanical tappets for higher revs, and was stress relieved using a slowed cooling process that minimized internal stresses. It used a cast iron crankshaft, and had grooved main bearing journals for improved lubrication. There were forged connecting rods borrowed from the now-discontinued high performance 390. The 427 was the only Ford big-block to use forged pistons.

The intake manifold and cylinder heads were designed and flow-tested to work together with either a high riser, a medium riser, or a low riser induction system. It was available with either a single 4 barrel carb or, for maximum output, a dual 4 barrel configuration with an aluminum manifold. Ford did not publicize the measured dyno Hp of these engines, but it was more than 500 hp for either engine. Camshafts were revised so many times on these engines that the entire alphabet of single characters was exhausted and double letters were used as the last two digits of the part number. On the tracks, the high-riser 427 was so successful that NASCAR eventually banned it. Ford rated the low riser 4 barrel 427 at 410hp at 4500rpm and 476lb-ft of torque at 3400rpm. The dual 4 barrel version was rated at 425hp at 6000rpm and 480lb-ft of torque at 3700rpm.
