The second-generation Australian Ford Falcons—the XR, XT, XW and XY—represent the era when the Falcon truly became a performance icon. These models introduced V8 power, GT variants, stronger drivetrains, and unmistakable styling, making them some of the most desirable classic Australian cars today.
Whether you’re buying a weekend cruiser, restoration project, or long-term investment, knowing what to look for with each model is critical. Values vary wildly based on authenticity, rust, driveline originality, and GT provenance.
This guide walks through common problem areas, model-specific issues, and buying tips to help you avoid expensive mistakes.
1. Body & Rust – The #1 Deal Breaker
Rust is the single most important issue on XR–XY Falcons. Many cars look good from ten metres away but hide serious corrosion.
High-Risk Rust Areas:
- Front chassis rails (especially near steering box mounts)
- Plenum chamber under the windscreen
- Sills and dog legs
- Rear quarter panels
- Boot floor and spare wheel well
- Firewall around heater box
- Doors (bottom seams)
Warning:
Rust in chassis rails or plenum chambers is costly and time-consuming to repair. Walk away unless priced accordingly.
2. Engine & Drivetrain Checks
Second-gen Falcons offered a wide range of engines—from economical sixes to legendary V8s.
Common Engine Options:
- 170 / 200 / 221 / 250 inline six
- 289 Windsor V8
- 302 Windsor V8
- 351 Windsor V8 (XW/XY GT)
What to Inspect:
- Oil pressure when warm
- Excessive top-end noise (especially on 250 sixes)
- Oil leaks from rear main seals
- Cooling system condition (overheating is common)
- Carburettor originality and tune
- Engine number matches compliance plate (critical for GTs)
Tip:
A tired 351 GT motor can cost $15k+ to rebuild correctly.
3. Transmission & Differential
Gearbox Options:
- 3-speed manual
- 4-speed Top Loader (desirable)
- Ford-O-Matic / Cruise-O-Matic automatics
Buyer Checks:
- Smooth shifting under load
- No crunching into second gear
- No clunks from tailshaft
- Diff whine under acceleration or deceleration
Desirable combos:
- 4-speed manual + V8
- Factory LSD (often missing or worn)
4. Suspension, Steering & Brakes
These Falcons were tough but age catches up.
What to Look For:
- Excessive steering play (worn boxes common)
- Cracked control arms
- Sagging rear leaf springs
- Worn king pins (early XR/XT)
- Brake fade or pulling under braking
Upgrades are common (disc brakes, poly bushes), but originality affects collector value.
5. Interior & Trim Authenticity
Original interiors dramatically affect value.
Inspect:
- Dash cracks (especially XR/XT)
- Correct seat patterns and trims
- Working gauges and switches
- Original steering wheel
- GT-specific interior items (XY GT especially)
Reproduction interiors are available but reduce originality value on high-spec cars.
6. Model-Specific Buying Notes
XR Falcon (1966–1968)
- First Falcon V8
- Early build quality can be inconsistent
- Check steering box mounts carefully
- GTs are rare and often cloned
XT Falcon (1968–1969)
- Improved suspension and brakes
- More refined interior
- Still rust-prone in plenum and sills
- GTs highly collectible
XW Falcon (1969–1970)
- Introduction of 351 Windsor
- Stronger driveline
- Less rust than earlier cars but still inspect carefully
- GT replicas common
XY Falcon (1970–1972)
- Most desirable Falcon generation
- Home of the legendary XY GT-HO Phase III
- Chassis cracks possible on hard-driven cars
- Extensive cloning – paperwork is EVERYTHING
7. GT & GTHO Verification (CRITICAL)
If you’re considering a GT or GTHO, verification is essential.
Always Check:
- Body and engine numbers
- Compliance plate
- Factory documentation
- Matching driveline components
- Expert inspection
Rule of thumb:
If the price seems too good, it’s almost certainly not genuine.
8. Modifications vs Originality
- Mild upgrades (brakes, suspension) improve drivability
- Engine swaps hurt collector value unless period-correct
- Original paint and trim carry a premium—even if imperfect
Decide early whether you want:
- A driver
- A show car
- An investment
9. Market Value & Investment Outlook
- XR/XT values rising steadily
- XW strong due to 351 availability
- XY remains blue-chip Aussie muscle
- GT and GT-HO values driven by provenance
Well-documented cars outperform freshly restored but undocumented builds.
Final Advice
The XR–XY Falcon era is where Australian muscle truly began. Buy the best body you can afford, verify everything, and never underestimate rust repair costs. A solid, honest Falcon will always outperform a shiny problem car.
