Gentleman’s hot rod
Farrah sits in the sweet spot of Ford’s 1966 lineup: smaller and sharper than a full-size Ford,
more grown-up than a Falcon, and less obvious than a Mustang. The GTA package adds the 390 FE,
bucket-seat character, console shift identity, and a restrained performance look.
The production sheet lists the 1966 Fairlane 500 XL GT 390 CID convertible as body/style 76D.
That is the line item that matters for Farrah’s identity.
The NHRA specification sheet gives hard reference data for 1966 Fairlane 390 combinations,
including 265, 275, 315, and 335 hp entries. The top Fairlane 390 listing shows 335 hp,
10.10:1 compression, Holley carb references, and C6AE-D / C6AE-H head references.
390 bore/stroke: 4.052 x 3.784
335 hp 390 compression: 10.10:1
335 hp Fairlane carb refs: Holley C6OF-M / C6OF-N
Transmission identity: Sport Shift Cruise-O-Matic / C6 automatic context
The wiring manual belongs beside the identity card because it is the practical troubleshooting map:
charging, starting, gauges, lights, horns, radio, heater, wipers, and warning systems.
Period test coverage of the 390-powered Fairlane GT/A, including transmission notes,
quarter-mile context, body structure details, and factory performance data.
The period ads capture the exact Ford sales pitch: GT/A, Sport Shift automatic,
390 confidence, and the mid-60s performance-family personality.
