Here you see the 428 cid V8 engine with the "Le Mans" cylinder heads and the (1968) "Cobra Jet" air intake of the GT-500 shown on this page. Really a piece of no-nonsense engineering: there's no substitute for cubic inches (and oversized fittings) as they say in America. It's all accessible and relatively easy to maintain for a thoroughbred car.
Like stated the GT-500 engine cranked out close to 400 hp and with the car weighing some 1360 kg, it had a ratio of 3.4 kg per horsepower. Compare that to the 5.7 kg per horsepower for the contemporary and more nimble Porsche 911 S and you'll understand this car was a thrill to drive.
The 1967 Shelby Mustangs can be regarded as the last true Shelbys and are the most interesting of all in my opinion. I love these cars, even without starting the engine you'll feel great in it. Still, production was relatively limited with 1,175 GT-350s and 2,050 GT-500s. Apparently there were a few (less than 50) GT500s produced with the 427 cid Medium Riser engine.Home
