1963 1/2 Ford Galaxie 500 Lightweight factory racer, 1-of-212, in storge since 1970, with only 2400 miles on it (thank you George!)

The portly front bench seat was ditched in favor of a pair of basic Bostrom bucket seats. These were sourced from Ford’s police package and saved a bunch of weight. The heater, radio, clock, armrests, door pulls, dash padding, dome lights, and even the passenger sun visor were all ditched. Instead of carpeting and sound deadening, the car just got a thin rubber mat. Made with aluminum bumpers, aluminum Borg Warner transmission, bellhousing, and shifter

the dual qual 427 lightweight '63.5 Galaxie

A mid-year addition to the full-size Ford lineup.

 Along with the new profile, Ford offered a lightweight package intended for racing that featured a stripped interior and a host of custom-built body and trim panels. 

The hood, fenders, decklid, and fender liners were molded in fiberglass. 

The bumpers and bumper mounting brackets were aluminum rather than steel. 

The case for the T10 four-speed transmission and its bellhousing were also aluminum, and it used a lighter chassis than run-of-the-mill Galaxies. The diet shed several hundred pounds from the car, making the dual-quad 427 V-8 even more impressive.

the R code 4 door Holman Moody '63 Galaxie

It's believed to be the only four door Galaxy built for racing.

It was ordered in 62 by Len Lukey and delivered pre-paid to Australia

Only that upon arrival all the light weight panels, bumper and brakes had to be replaced with stock items as the rules at the time was for 'Production Sedans' and these items were not available to the public at the showroom in Australia. It is R code and came with the 427 low riser

After a period of being driven as a road registered car, and after much effort Gary Smith tracked the car down and purchased it from the outer north eastern suburbs of Melbourne. After moving to Perth, the car was sold to Wayne Holland, who sent it to Marc Ducquet in NSW for sorting and an engine rebuild. This was at approximately the same time Marc was preparing his fastback. The fourdoor then returned to Gary in Perth and was raced in (historic) Appendix J class for several years.

David Bowden owns this car. Soon after purchasing the car from Wayne, the car was given a full mechanical restoration, and is now on display in the fabulous racing car collection David has on display in Australia.

1963 1/2 Ford Galaxie codes indentified

There certainly is no shortage of under-hood offerings from Ford. While the 260-cu.in. engine had been available at the beginning of the 1963 model year, it had been replaced by the 289-cu.in., 195hp block equipped with a two-barrel carburetor, or C-code engine. The 220hp X-code 352-cu.in. engine is just the tip of the iceberg for optional offerings. The 352 contains a 4.00 x 3.50-inch bore and stroke, with a 8.9:1 compression ratio topped by a two-barrel carburetor.

If neither of these whets your appetite, try locating a Fastback with one of the 390-cu.in. engines installed, the first being the Z-code 300hp version. The P-code 330hp version is also equipped with a four-barrel. Both 390 blocks feature a 4.05 x 3.78-inch bore and stroke with a compression ratio of 9.60:1 and a torque rating of 427-lbs.ft. at 2,800 and 3,200 rpm, respectively.

Next up is a pair of 406-cu.in. engines, each with the same 4.13 x 3.78-inch bore and stoke and 11.40:1 compression ratio; however, horsepower and torque rating differed, as well as carburetors. The B-code block sports a four-barrel carburetor resulting in 385hp and 444-lbs.ft. of torque, while the G-code edition bangs out 405hp and 448-lbs.ft. of torque thanks to three two-barrel carburetors.

The mid-year inclusion of the new 427-cu.in. powerhouses is what really sets collectors hearts on fire. With a 4.23 x 3.78-inch bore and stroke and an 11.5:1 compression ratio, a 427 equipped with a four-barrel thumps out 410hp and 476-lbs.ft. of torque (Q-code), while dual four-barrels result in a teeth-clenching 425hp and 480-lbs.ft. of torque (R-code). This last example was installed in only 3,857 vehicles, according to Reynolds.

1,038 Q-code models; that's a 410hp 427 monster
