A previous head and exhaust test (August '13 issue) on this '64 Sport Fury leads us to swap out the cam. Switching to a cam with more lift would mean more air flowing through the new Edelbrock heads and tti 3-inch exhaust to produce more power. We would ditch the outdated hydraulic stick for a modern solid street-roller with more valve lift (solid .570/.576 vs. hydraulic .474/.474-inch) while having close to the same duration (solid 242/248 at .050-inch vs. hydraulic 238/238 at .050-inch). We did retain the same lobe separation angle (110 degrees). This type of cam swap will liven up most any engine with increased grunt throughout the engine's rpm scale.
