Ford Mustang 1967 GT Convertible 289

Only 472 Mustangs left the factory in 1967 with the high-performance 289 V8 under the hood, making this Wimbledon White convertible a genuine rarity rather than just another pretty color combination. The GT package that came with it wasn’t cosmetic — it required dual exhaust and forced buyers into the hottest engine Ford offered that year short of a big block. Here’s what actually separated a true 1967 GT 289 from the more common six-cylinder cruiser.

This is a sweet 1967 Mustang GT Convertible 289 in Wimbledon White!

Out of the hundreds of thousands of Mustangs Ford built for 1967, only 472 left the factory carrying the high-performance 289 V8 — a number so small that most Mustang owners will go their whole lives without seeing one in person. This particular convertible, finished in Wimbledon White, is one of that small group. The GT package bolted to it wasn’t just a stripe kit or a badge; Ford required specific hardware to earn the name. So what did a genuine 1967 GT 289 buyer actually get for their money, and why did so few people order it?

The Rarest Engine on the 1967 Order Sheet

The Hi-Po 289 V8 produced 271 horsepower at 6,000 rpm and ran a 10.5:1 compression ratio with a 600 CFM Holley four-barrel carburetor — aggressive specs for a small-displacement engine in 1967. Period testing put a 289-powered Mustang at 7.3 seconds to 60 mph and a 15.2-second quarter mile at 91 mph, brisk numbers that made the Hi-Po the enthusiast’s choice over the more common two-barrel small blocks.

What the GT Badge Actually Required

Ford‘s GT package for 1967 wasn’t optional trim dressing — it required dual exhaust as standard equipment and was mandatory for anyone ordering the 271-horsepower 289. That pairing meant a genuine GT convertible with the Hi-Po engine represented the top of the small-block Mustang hierarchy that year, one step below stepping up to a big-block car entirely.

With a curb weight around 2,980 pounds for the convertible body and a 108-inch wheelbase shared across the whole 1967 lineup, the GT 289 convertible balanced genuine performance against everyday usability better than the heavier big-block cars that followed. Given the 472-unit production figure, surviving examples like this Wimbledon White car are among the rarest documented Mustangs from the era.
