Actually, I've had a facsimile copy from when fax paper came on rolls! And it's faded pretty bad, and for some reason I can't find the rest of the article (this was stashed in a 1989 copy of Excellence).

Anyway, it is certainly C&D, I believe it is late 1977 reviewing the up-coming 911SC. Cookie-cutter (ATS?) wheels, chrome targa bar.

On the spec page it shows

172bhp @ 5,500
189lbs-ft @ 4,200

0 - 60 in 5.5 sec
-70 in 8.1
-80 in 10.3
-90 in 13.0
-100 in 17.0
1/4 mi in 14.8 sec at 94.0; top speed [factory rated] 136mph

Remember, though, that the early 3.0 litres ran with pretty advanced cam timing -and the 15" wheels offer shorter gearing than the 16"s more commonly seen on the 78-and later cars.
That might explain why the car peters out to an anemic 14.8 quarter mile after charging out of the gate so hard.

Also, here's a little something for you drag queens ( ): even though first gear has rocket-like take-off, consider shifting out of first by 5,00 to 5,600 rpm. You won't beat up the synchros, and it is an incredible quick shift that puts you out of first just out of peak power and into second right on the bottom of the torque curve. Plus, it is an incredbily quick but gentle shift to boot.

The bottom line is if you take the second gear ratio of 1.77 and divide it by the first gear ratio of 3.18 you will see the optimum shift point rpm expressed as a decimal: 5566, or 5600 rpm. (post 1978 and USA cars. (915/61))

The C&D example had the shorter 1.83 2nd gear, so the shift point moves up to 5,700 rpm. (78 and Euro SC: 915/63)

The test car had the shorter 2nd gear as well.
