Looking at historical printing from back in the days.

What seems to be a stock or not modified Shelby Hertz vehicle we come up with this.

Your thoughts on these "Black & Gold Bad Boys"?

That was one of the "prototypes" note the 15" Crager style wheels and the "Smooth" style interior seat upholstery, That's a 65 style, not 66 
Owned since 1971, NOW DRIVEN OVER 250,000 MILES, makes me smile every time I drive it and it makes me feel 21 again.😎

On the Bonneville Salt Flats in 1973 we saw an indicated 126 MPH at a little over 6250 RPM's with E-70 Firestone Wide Ovals driving back from around the 6 miles marker one evening. We exceeded the requested speed limit by a "little" bit

Car & Drivers results appear to be pretty darn close to this example.

Fuel mileage looks right also. Worth every penny.

Seems quite close to what it should run.

My 68 with 3.50 gears and a little bit of work on the 302 ran 14.5's.

6S1431 ran a bunch of times down the 1/4 mile at Capital Raceway in Crofton Maryland. mostly with a range of 14.1-14.2  91-92 MPH. Best ever was with a fresh tune-up and a cool evening 14.08 at 93.1 mph, never hit a 13 second ET

Oops I meant to say 15.1-15.2 with a best of 15.08, never hit a 14

Back in the day a lot of magazines would fudge a couple tenths over what the manufacturer (or another magazine) published. Maybe it was the buy our mag we test harder or are better at wringing the max out of it. Then there was the fact that NO ONE ever tested a car right off the line. They were all tuned to the max before they got loaned out.
When Titus did the Hot Rod article on the Dodge Omni v GT350 article the car was well tuned but withing stock specs. After all the hate mail for beating the GT350 we took one to a COCOA Willow event so the haters could see it in action. CS did admit this one had a different tune with a 20 hp boost. He wanted to make sure it couldn't lose.

SLOWER THAN A MANUAL. I know.....

6.6 seconds 0-60 is very respectable for a car of the 60s. Only a couple of seconds slower than some of the exotics of the 2000s...

Does the weight figure seem a little higher? I thought they were sub 3000 lbs, or was that the 65?
