ETs for '65/'66 GT350s

Ok, this is for my 67 GT 350. So add 300-400 pounds over a 65/66 car. Stock it would run 15.20-15.30's all day. After installing headers, a bigger carb (750 cfm) a little head work (shaved .030, springs, valve job) it ran 14.56 beast and always between 14.60-14.80's with open headers, no slicks. Oh, this was back in 1971/1972.

 

I concur. My bog stock '67 GT350 ran mid 15s with 4-speed, 3.89 rear, tri-Y headers and street tires.

Depending on the car and how much abuse the driver was willing to put it through, times varied from low 15's to mid 14's. The over ride traction bars on a 65 were the forerunner of the modern 4 link suspension. These cars didn't tend to suffer from startline traction problems like a lot of the big block muscle cars did.
Car Life Magazine devoted an entire issue to the Mustangs and Shelbys. They listed these times and speeds:

65 Mustang, 271 H.P. 15.9 85 MPH
65 GT-350 14.7 90 MPH

Those are very respectable times by 1965 standards.
