1969 Chevrolet Corvette Stingray


The big bulge in the center of the domed hood on an early third generation Corvette serves the same purpose as black and yellow stripes or rattly tail scales do in the animal kingdom; it's a warning that this is a car with which one should not trifle.

The one-word cursive "Stingray" script on the fenders and the all-black grille inserts tell us that this is a 1969 'Vette, and the "427" on the hood bulge and sewer-pipe-sized side pipes tell us that it is down to party.

For 1969 the absolute tamest 427 that could lurk in the engine bay of this Le Mans Blue coupe with a Bright Blue interior is the L36, with a single four-barrel Rochester Quadrajet, hydraulic lifters, and a 10.25:1 compression ratio, rated at 390 SAE gross horsepower. Opting for the L68 427 got you basically the same juice-lifter engine but with three two-barrel Holley carbs and 400 horsepower.

Next rung up the performance ladder was the solid-lifter, 11.0:1 compression Tri-Power L71, which made 435 ponies, and then there was the gnarly 4-barrel L88 which, despite having the same solid lifters as the L71 as well as a 12.0:1 compression ratio and fresh air induction to boot, mysteriously was only rated at a (completely fabricated) 430 horsepower. 

There was also the semi-mythical all-aluminum ZL1 427, of which only two were sold, and which was also rated at "430" hp. Like the L88, it required 103 octane Sunoco racing gas.

Of the big block '69 Corvettes, something like 10,500 were fitted with the L36, while there were only a couple thousand each of the L68 and L71. Only 116 L88 cars made it off showroom floors and into the wild.


In October of 1968, Car and Driver tested a 1969 Corvette coupe with the L71 Tri-Power motor, Muncie M-22 four-speed close ratio gearbox, side pipes (a $146.70 option!), and optional 3.70:1 Positraction rear end.

The car ripped off a 5.3 second zero-to-sixty run and a 13.8 second quarter mile at 107 mph. Price as tested was $6,573 (or $56,471 in today's dough), which price included almost two grand's worth of options. 

This one was photographed in September of 2021 using a Hasselblad Lunar and Sony Zeiss Vario-Tessar T* 16-70mm f/4 OSS zoom lens.

  1. L88 had a single four barrel carb, the L89 used the tri-power setup but also different heads and cam and was rated at 435 hp. The L89 was also more of a street motor compared to the all-race L88 despite the horsepower ratings.

    1. That's what I thought from earlier years of the L88, but I guess I believed CorvSport for the '69?

    2. You are, of course, correct, and the normally anally correct CorvSport sit is sitting on quite a typo here.
