Once upon a time. Aston Martin made a big thing out of going from zero to 100 and hack to zero in less than 30 seconds. Ken Miles took one of the street 427 machines out and did zero to 100 to zero in 13.2 seconds. This was done on concrete. On asphalt things get a bit slicker. Due to wheel spin with the street tires (Goodyear Blue Dots), and the fact that the straight at Riverside had been used for a big drag meet wherein several cars had grunched on the line, the best we could get with the street machine was 110 mph in 13.2 seconds through the quarter. It was the first street machine we'd ever driven that would keep the tires lit up for the full quarter in every gear. The race car, with its "blueprinted" engine and huge rear tires, got a full second off of that, blasting through the trap at 6500 in third gear.

At one point we were entering a freeway and pausing at the entrance. Our passenger looked at the traffic and commented "Careful, the traffic is moving pretty fast - wasn't it! That was how long it took to get up to and above the normal 70 mph flow of cars. To be very blunt about it, we do not advise those not extremely well-versed in the Cobra mystique to try the shenanigans conducted by Ken Miles in this car.

The street 427 has two Ford-made frour-barrels supplying fuel to the powerful engine.  This setup produces almost as much torque at the bottom end as the competition version does.

Looked at as a whole, the Cobra 427 is not a machine for general transportation. It is, rather the latest example, and very probably the pinnacle, of that vanishing breed, the pure sports roadster. Its water-tight integrity is on the minimal side, and it wouldn't be much fun to drive in most urban areas, particularly east of the Mississippi. It can be used for travel and there is considerably more room in both trunk and cockpit than in past versions, but best the weather be good and the spaces traveled be wide.

Our test car of the street version was bright red and we were thankful that in our area the law enforcement agencies are reasonably tolerant of such machinery, and that the exhaust system of the 427 is virtually silent except at full throttle. Painted red, this car is one that in some areas could get you a ticket while parked in a driveway. To sum up, our early misgivings to the contrary, the Cobra 427 rides comfortably and is bags of fun as long as one puts the brain in gear before putting the car in gear. One might get a bit wall-eyed keeping one eye on the road and the other on the rear view mirror, but that's been the name of the game for years, and a small price to pay for the privilege of driving a machine not seen on the road since the days of the Mercedes race cars of the 1930's.

We tested both the street version and the track machine. For this last, we will now turn you over to Jerry Titus:

The racing 427 uses a single Holley with its centerpivot floats.  It has a rating of 780 cubic feet per minute.  Output from the 7000cc monster is 485 horses with 480 lb.ft. torque.
