The XA carried over the same
six-cylinder engines previously offered on the XY Falcon range. In response to the growing popularity of its V8 engine options and the expense of importing V8s from North America, Ford Australia began local manufacture of the
Cleveland V8 at its Geelong plant. As well as building the 351 cu in () variant, it developed a de-stroked variant of this engine to replace the imported
Windsor 302 engine. The high-performance variant of the 351 with four-barrel carburettor continued to be imported, eventually being replaced with a locally-produced variant during the XB model run.

Grand Sport Rally Pack A Grand Sport (GS) Rally Pack was offered on Falcon, Falcon 500 and Fairmont models. The XA GS had rally stripes that ran from the front indicators to the end of the rear doors. It also shared many options as used on the GT Falcon, such as the 12 slot steel wheels with plain brushed centre caps, the three spoke wooden rimmed steering wheel with rim squeeze horn and full GT dash instrumentation featuring tachometer, odometer, oil pressure, water temperature and voltmeter as standard. For the first time the GS model range was also available as a two-door hardtop. The GS package was also offered as an option on
utes and
panel vans as per XY. The two barrel version of the
Cleveland V8 was the largest engine option available. The GS option did not come standard with the Option 56 ‘driving lights’ grille which was standard on the GT, however it was a common addition. The GT
bonnet with
NACA style ducts was not available as an option on the XA GS.
Falcon GTHO Phase IV As the previous XW and XY series Falcon GT sedans, an extra-high-performance limited-production version of the XA Falcon GT sedan, the GT-HO Phase IV, was developed by Ford Australia for homologation in
Group E Series Production Touring Car racing, targeting in particular the
1972 Hardie-Ferodo 500 at Bathurst. Production of the required 200 examples was abandoned in July 1972 following
intense media and political pressure, and only one production example was completed. This significant road car was manufactured in Calypso Green metallic with a white vinyl interior, and has recently been completely restored. Additionally, three regular production Falcon GT sedans - especially painted in Brambles Red - had been in the process of being developed for racing to GT-HO specification by Ford Special Vehicles Division and were to be raced at Bathurst in 1972 by
factory drivers
Allan Moffat and
Fred Gibson. With the abandonment of the XA Falcon GT-HO as a production car, development was immediately halted on the three race cars and they were sold off. However, one of these cars did go on to serve a life in motorsport, specifically as a rally car campaigned by Bruce Hodgson. It was later destroyed in a road accident. Although the three cars featured standard Falcon GT compliance plates, they are considered by most Ford fans to be race-prepared versions of the XA Falcon GT-HO Phase IV. Howard Marsden, head of Lot 6, designated the race cars as follows XA-1 Allan Moffat (Carthew); XA-2 Gibson (Bowden); XA-3 (Hodgson).
Falcon GT - RPO 83 Between April 1973 and August 1973, Ford Australia built 250 XA Falcon GTs fitted with the RPO 83 package, 130 of these being sedans and 120 being hardtops. RPO 83 comprised three variations from the standard XA Falcon GT, these being of a Holley 780 carburettor, 2.25 inch exhaust headers and a clutch slave cylinder hydraulic pipe heat shield. The production Superbird was an XA Falcon 500 Hardtop fitted with an option package designated as RPO 77. Large "Superbird" decals adorned the rear quarter panels and the rear-mounted "Falcon 500" badging was retained. however, the actual production total is thought to have been lower. The entire production run was completed in the months of March through May 1973. . ==Motorsport==
