Need Cobra 427 Info

Home  \  Classic Cars  \  Need Cobra 427 Info


I've been looking everywhere for information on either a '67 or '68 Shelby Cobra 427. What I need is the type of engine, Top speed, how fast it can go from 0-60, it's displacement, Max power--e.g. 425 bhp @ 6,000 rpm, Max Torque--e.g. 460 lb-ft at 4,000 rpm, and it's weight.

I'm also looking for some other information such as:
Transmission info
Running Gear including: front & rear suspension, brakes, wheels, and tires
and it's Overall dimenisions including: length, height, width, wheelbase, track front and back.

I would most appreciate if I could get this information. it's been extremely difficult for me to locate this information. I don't want modified engine info. I would like to have all original specs.

I can be contacted at

1966 Shelby Cobra Road-test results
0 - 60 mph3.6 seconds
0 - 100 mph8.4 seconds
0 - 130 mph15.1 seconds
1/4 mile12.0 seconds @ 118 mph
Top speed152 mph (redline)

"...14.5 seconds to accelerate to 100 miles an hour and then stop again. Until something better comes along, that may have to stand as some sort of high water mark in performance cars that are available to the general public. That figure, mind you, is obtainable by the average Cobra driver with regular street tires. Cobra test driver Ken Miles has done it in 13.8 seconds."
-Brock Yates on the 427 Cobra, Car and Driver, November 1965

Not sure the difference between 66 model and 67 model

Thank You soooooo much, if it weren't for your time and effort, I wouldn't be able to get this website off the ground. I think I'm going to give you a dedication in it for all the help you've given me. I don't know what I would have done without this information. I've gone as far as buying the Complete Encyclopedia of Classic Cars and it wasn't all that it was cracked up to be, well for me. So, thank you again.
