Ford Falcon XA GT RPO 83 Hardtop
The 1971 Ford Falcon XA GT RPO 83 Hardtop represents the dramatic evolution of Ford Australia's GT performance program following the legendary Phase III. Built on the all-new XA Falcon platform, the RPO 83 (Regular Production Option 83) was the spiritual successor to the GT-HO series, offering serious performance in a striking two-door hardtop body that many consider the best-looking Falcon ever produced.
The XA body, designed in collaboration between Ford Australia and Ford's Dearborn studios, was a significant departure from the earlier XY. The sleeker, more contemporary styling featured a distinctive shark-nose front end, flowing body lines, and in hardtop form, a pillarless roofline that gave the car an elegant, almost European appearance. The two-door hardtop body was specifically chosen for its lower weight and increased structural rigidity compared to the sedan.
Power came from the 351 cubic inch Cleveland V8 producing 300 horsepower (SAE gross), essentially the same engine specification used in the Phase III. The R-spec Cleveland featured high-compression forged pistons, a solid-lifter camshaft, 4V heads, the 780 CFM Holley carburetor with ram-air induction, and tuned headers. This was as much engine as Ford Australia ever installed in a production car.
The RPO 83 designation identified the specific performance package that included the full GT-HO-specification engine, close-ratio Toploader four-speed manual transmission, limited-slip differential with 3.25:1 ratio, heavy-duty suspension with upgraded springs and anti-roll bars, power-assisted ventilated front disc brakes, and the ram-air bonnet scoop.
The XA's chassis was more modern than its predecessor, with improved geometry and revised suspension pickup points that enhanced handling. The front suspension retained the double-wishbone layout with coil springs, while the rear used a live axle with leaf springs, both with heavy-duty components specified for the RPO 83 package.
The interior featured the full GT instrument pack with tachometer, oil pressure, water temperature, and ammeter gauges. Sports bucket seats with high-backed design provided improved lateral support. The steering wheel was a smaller diameter three-spoke design that gave the cockpit a purposeful feel.
The RPO 83 Hardtop was built in extremely limited numbers -- fewer than 300 units -- making it one of the rarest production Falcons. The combination of the XA hardtop's beautiful styling, the Phase III-level performance, and tiny production numbers has made it one of the most sought-after Australian muscle cars.
Political pressure from the Australian government, which was concerned about the so-called 'supercar scare,' limited Ford's ability to market the RPO 83 aggressively. The car was ordered by request only, and Ford did not widely advertise its availability. This quiet release has contributed to the model's mystique and collector desirability.
Extremely rare and valuable -- authentication through Ford Australia records is essential. Verify RPO 83 option on build sheet. The XA Falcon body is prone to rust in inner guards, sills, floor pans, and around the rear window. Matching-numbers drivetrain is crucial for top values. Many standard GT and GS XA Falcons have been modified to appear as RPO 83 models.
Built at Ford Australia's Broadmeadows plant in Melbourne. The RPO 83 option was a special order item, not listed in standard brochures, due to the Australian government's 'supercar scare' pressure on manufacturers.
