The 1963 Ford Galaxie 500XL offered buyers a spread of engines topped by an all-new 427-cubic-inch V8, built specifically to exploit NASCAR’s newly raised displacement limit. The rarest version, a dual-carburetor 425-horsepower R-code, saw fewer than 3,900 examples built for the entire model year. That combination of race-bred engineering and genuine scarcity makes surviving R-code Galaxies among the most valuable full-size Fords ever built.
The only full sized 1963 Ford is the Galaxie, which could be ordered in the higher performance 500 or top of the line Galaxie 500XL.  223 cu in (3.7 L) six cylinder engine is available. There is also a choice of six larger power plants including a 427 cu in (7.0 L) SE series V8 at the top of the list. The engine could be coupled to the three speed Cruise-O-Matic automatic or the three speed standard transmission on a factory correct model.

Ford built exactly one full-size model for 1963 that could be ordered with a docile 3.7-liter six-cylinder or a genuinely formidable 7.0-liter V8 wearing dual four-barrel carburetors, and almost nobody chose the six. That top engine option existed for one reason: NASCAR had just raised its displacement limit to 7.0 liters, and Ford wanted a homologated weapon ready before the green flag dropped. Fewer than one in ten buyers who picked the sportiest XL trim went all the way to that dual-carb engine, making it one of the rarest combinations Ford ever built into a full-size car. What made this particular engine option so significant that it’s still chasing six-figure prices at auction today?
One Nameplate, Seven Engine Choices
For 1963, the Galaxie was Ford’s only full-size offering, available in base, 500, and range-topping 500XL trim, with the sportier XL adding bucket seats, a center console, and upscale vinyl trim. Buyers chose from a spread of engines starting with a 223-cubic-inch six and running through six different V8 options, all routed through either a three-speed manual or Ford’s three-speed Cruise-O-Matic automatic.
The 427 That Was Built for NASCAR, Not the Street
Sitting at the top of that engine list was the new 427-cubic-inch V8, introduced specifically to exploit NASCAR’s new 7.0-liter displacement ceiling. It came in two states of tune: a single four-barrel “Q-code” rated at 410 horsepower, and a dual-quad “R-code” version making 425 horsepower and 480 lb-ft of torque. Ford built the 427 with a forged rotating assembly, a high-lift cam, and high-flow heads to survive real racing abuse, and a fastback roofline arrived mid-year specifically to cut drag on NASCAR’s high-speed ovals. Only 3,857 R-code cars were built for the entire model year, a rarity that keeps genuine examples among the most sought-after full-size Fords from the era.
