The Ford Galaxie 500 R-code high-performance package for the 1967 model year included heavy-duty driveline and suspension components with its 427 cubic inch V8. It includes custom front and rear suspension, a new differential, cold-extruded axle shafts, and universal joints. Moreover, clients could specify their 7.0-liter V8s with NASCAR-inspired high-rise heads, a custom intake manifold, and larger-diameter rectangular intake ports to produce upwards of 500 horsepower.
By the late 60s, the 427 had proved its merits in professional racing and was approaching its twilight years, taking the checkered flag at the 1966 Le Mans 24 Hours that powered the iconic Ford GT. It also gathered NHRA championships, set Bonneville speed records, ignited NASCAR race tracks, and climbed Pikes Peak.
However, the muscle car era was in full swing, and enormous barges with potent V8 engines like the Galaxie gave way to smaller, lighter vehicles with equally gigantic powerplants, paving the way for the muscle car era and legendary names like Mustang, Camaro, and GTO.
