XY and XA models overlapped, they actually kept making some XY until 1972 and XA started 1971 so there will be a slight power difference depending which model but just in case the link don't work here it is.

XY Falcon November 1970: The last of the second generation line. Big 250ci(4.1L) six introduced. This was when the mighty GTHO Phase III was unleashed on the motoring world. The result was first, second and third places at bathurst in 1971.
While the XY was not greatly changed from the XW, it proved to be even more popular, continuing the Falcon's steady progress towards market leadership. Refinement of a proven design was the key theme to XY and a major reason for the model's success.
The facelift was certainly minor, much more so than in the transition from XT to XW, with the revised frontal treatment being the most obvious difference. On XY the headlights were enclosed within the grille which was bisected by a vertical bar and this design accentuated the Falcon's width. The rear was also clearly revised and once again a full width horizontal strip linked the lights.
At the top end of the XY lineup, the GTHO went into legendary Phase III mode to become the most collectable Falcon ever, aside from the Phase IV, of which just four examples were built. And the 351 engine was now sourced from Cleveland rather than Windsor.
For most Falcon buyers though the really big news was the availability of the new 250 cubic inch six-cylinder engine. The 250 replaced the 221 as the topline Falcon six, offering substantially more power and torque and thereby contributing greatly to the XY's overall refinement.
The Holden 186 and even the 186S were outclassed for effortlessness and sheer loping performance. Ford Australia's marketing people were keen to promote the 250 as an alternative to the General's 253 cubic inch V8, but it must be conceded that the so-called 'little' V8 did offer an edge in both performance and image.
Of course, those who wanted even more grunt could order the 302 V8 and-as if that weren't sufficient!-a two-barrel edition of the 351 cubic inch engine was now on offer as optional equipment across the whole Falcon range. The four-barrel 351 fitted exclusively to the GT now developed 300 (gross) brake horsepower at 5400 rpm, which was up 10 from the XW and 380 lb/ft or torque at 3400 rpm. By contrast the de-tuned version gave 250/4600 and 355/2600 respectively. The compression ratio was an almost modest (by comparison) 9.7 to 1 rather than the 11 to 1 of the GT.
The two-barrel 351 offered a level of performance which put it almost midway between the 302 and the four-barrel 351. For those who wanted more urge but without having to go all the way to a GT, the GT's dual exhaust system was optional and did offer enhanced performance as well as providing a richer note.
New options for the XY range included a sliding sunroof, eight-track cartridge player, alloy wheels ('mag' wheels) and lowered suspension (standard with all 351-powered Falcons, optional with 302s and unavailable with sixes).
The facelift was certainly minor but during 1970 to 1972 Ford had produced 118,666 XY Falcon's.

XA Falcon February 1972: New, Aussie styled Falcon owed nothing to it's overseas-inspired predecessors. Two door pillarless hardtop was introduced and options list stretched a mile. GTHO Phase IV production got to four cars before the 'supercar scare' killed it.
Sometime early in 1968 the decision had been taken to discontinue product' of the US Falcon. Thus it was that in May of that year, a team of Ford Australia executives flew to America to begin work on what was to become the 1972 XA Falcon. There they would collaborate with senior Dearborn stylists because the Australian operation was at that time considered to be too small to have complete autonomy.
Ford Australia's Product Engineering centre had yet to make the big move north from Geelong to Campbelifield and the studios were fine for the development of a new grille or strip of chrome but quite inadequate for the conception of a whole new shape. Very early on in the project the Americans suggested that an abbreviated version of the new Fairiane/Torino - a car of which they were proud - would do the joh. By using the centre section of the car in conjunction with a shorter wheelbase and shorter front and rear overhangs, an attractive car of Falcon dimensions could be created.
But the Australians had immediate doubts, believing that the effectiveness of the Fairiane/Torino styling was largely a consequence of those long, flowing overhangs and the long wheelbase. A clay model was built and everyone agreed that the Australians' reservations had been right. While the XA bears some resemblance to the Fairiane/Torino, it was in fact an all-new design.
In October 1968, work was cornpleted after three Australian designers had worked 90 hours. Dearborn was so impressed with the work achieved by the Australian stylists that Ford Australia was told to build itself a design centre.

Thanx for that, that's heaps of help just what i was after
