Seven liters! four hundred and also twenty-eight cubic customs in a Mustang! us were expecting a cataclysm ~ above wheels, the automotive indistinguishable of the end of the earth. We were pleasantly surprised to find that the GT 500 isn’t anything favor that.

The old corollary to that old adage, “There’s no substitute for cubic inches,” is “except rectangle-shaped money”–and that would know much better than Carroll Shelby. Once the Cobra 289 peaked out on the racetrack, there to be several ways of making it go faster–most expensive, one cheap. One of the more expensive means was the Daytona coupe body. The late Ken Miles uncovered a much better way. At Sebring in 1964, he shoehorned a Ford 427 NASCARized engine right into a Cobra roadster. The experiment came to rest, sorely bent, against a palm tree, however Miles persisted. By the end of the season, in ~ Nassau, the had another one bolted together. It go out up, however the dice was cast. At an early stage in 1965, Shelby announced the Cobra II v a 427 cu. In. V-8 instead of the 289. That June, in ~ Le Mans, 2 of Ford’s rear-engined GT prototypes showed up with the large 427 instead of the 289. The europeans hooted and jeered at the bulky, heavy, unsophisticated V-8 through its pushrods and single four-barrel carburetor. A year later, Ford 427s swept the an initial three areas at the French classic, with Shelby’s two entries dead-heating the final lap. What the 427s had beaten was a team of 270 cu. In. Ferrari V-12s with multiple carburetion and four overhead camshafts. The Italian engine developed nearly as lot horsepower as the Ford–425 hp vs. 485–but it to be much an ext tautly emphasize and, therefore, fragile. I m sorry is the whole allude of 7-liter Fords, Cobras, and now, Shelby Mustangs.


For "67, Ford offered the Mustang with their tried-and-true 390 V-8, which has actually a bore and stroke that 4.05 x 3. 78 inches. Ford likewise builds a 428 V-8 top top the very same block with a bore and stroke the 4.13 x 3.98 inches. Why not, reasoned Shelby, usage this engine in the "67 Shelby Mustang? Why no indeed. The vehicle is referred to as the GT 500 and also its engine is referred to as the Cobra Le Mans.


Somebody is telling a tiny white half-truth.

Please keep in mind that the Cobra Le mans engine displaces 428 cubic inches. That sounds choose a hair better than the 427. In fact, they are two entirely various engines. Both have the same external dimensions, yet the 427 is more oversquare, v a bore and also stroke the 4.23 x 3. 78. The 427 is a racing engine, complete of the type of minister fortitude that provides it qualified of enduring 500 miles at Daytona and 24 hrs at Le Mans. The 428 is a passenger-car engine, and practically $1000 cheaper 보다 the 427. Few people would certainly be happy through the 427 unless they were racing it. It’s noisy, balky, and also an oil burner at normal highway speeds.


The GT 500 is not a racing car, although but for a couple of subtle distinctions its engine is the exact same as the one that pushed Shelby’s Fords to success at Le Mans. 7 liters in a Mustang! The beforehand GT 500 design prototype to be the fastest automobile ever come lap Ford’s twisty handling loop, except for the GT 40s, of course. And also the same auto cut a quarter-mile in 13.6 secs at 106 mph. Super car!
