The Corvette - 1969
"A Top Ten Corvette"
As they usually are the year after a major model
introduction, changes for the 1969 Corvette were minor, made mostly to remedy
problems noted by owners and the motoring media. For starters, the
steering-wheel diameter was trimmed an inch for more under-rim thigh clearance,
and Duntov pushed through a $120,000 tooling change for the inner door panels
to open up a half-inch per side in extra shoulder width. Interior door handles
and control knobs were redesigned for safety's sake. The previous dash-mounted
ignition switch moved to the steering column, where it combined with the newly
mandated column lock for additional security. A warning light was added to
advise the driver that the pop-up headlights hadn't popped up completely.
Attempts were also made to increase Astro Ventilation flow volume, but the
system was still judged to be inadequate. Finally, a flexible dash-mounted
three-section map pocket was included to help make up for the lack of a proper
glovebox.
Besides many detail improvements for the 1969 Corvette, the Shark became a Stingray, gaining fender namescript with the same one-word spelling Bill Mitchell had used for his 1959-1960 race car.
| | Exterior alterations were likewise minimal; the most obvious
was the return of the Stingray designation (now spelled as one word) in script
over the front-fender louvers. Another change involved the door handles. New
single-lever door-handles replaced the conventional chrome handgrips with
thumb-operated pushbuttons. A new headlight washer system was added, and
windshield-washer jets were moved to the wiper arms. The already
over-engineered hidden-wiper arrangement became even more complex with the
addition of an override switch that allowed the vacuum-operated panel to be
left up in freezing weather. At the rear, the previously separate backup lights
were incorporated with the inboard taillamps. The frame was stiffened to reduce
body shake and standard rim width went up another inch -- to eight -- for
improved handling.
 The 1969 Corvette featured hidden windshield wipers beneath a power pop-up cowl panel.

Engine alterations, on the other hand, were more obvious,
seeing as how carmakers were in the second year of federally mandated -- and
still relatively straightforward -- emission controls. The famed Chevy
small-block was stroked about a quarter-inch to 3.48 inches, which boosted
displacement from 327 to 350 cubic inches on the same 4.00-inch bore. Corvette
offered 300- and 350-bhp versions, the same ratings as their 1968 equivalents
but with compression dropped a quarter point in each case -- to 10.25:1 and
11.0:1, respectively. Significantly, peak power engine speed was also lower by
200 rpm, to 4,800 and 5,600 rpm, respectively.
The big-block 427s returned unchanged, with ratings of 390
to 435 horsepower. The special aluminum-head L88 -- still rated at a modest 430
bhp -- remained among them, though its towering $1,032 price attracted just 116
buyers.
Two new performance options were announced for 1969: One was
extremely rare -- with only two installed -- the other was ostensibly available
but put back a year. The former was RPO ZL1, which was essentially the mighty
big-block L88 with all-aluminum construction plus numerous other modifications
including dry-sump lubrication. Devised for the British-built McLarens that
would dominate the SCCA's Canadian-American Challenge Cup series, this engine
had the same compression and carburetion as the L88 but weighed 100 pounds
less. It also carried the same 430-bhp rating, but that was a joke;
over-the-counter racing versions were reportedly good for 585 bhp. It lurked
beneath a special domed hood shared with the L88 (RPO ZL2) incorporating an air
intake at the high-pressure area near the base of the windshield.
Of course, Duntov hadn't dismissed the potential of
small-block power. Listed for 1969 but not available until 1970 (owing to
development and manufacturing problems) was a special solid-lifter version of
the new 350. Coded LT1, it was right in line with Duntov's longtime goal of
minimizing weight in a performance car growing heavier with every newly added
creature comfort. Unlike tamer small blocks, the LT1 had more radical cam
timing with more generous valve overlap, used the big-block engines' hefty
2.5-inch-diameter exhaust system, breathed through the same 850-cfm Holley carb
fitted to the L88/ZL1, and came with transistorized ignition. The result was
370 bhp at 6,000 rpm and 380 pound-feet of torque at 4,000 rpm. It was offered only
with a four-speed manual transmission, and a Corvette so equipped typically
streaked through the standing quarter-mile in 14.2 seconds at 102 mph. Visual
identification was subtle -- just the special domed hood with perimeter
striping and discreet "LT1" lettering -- but there was no mistaking
the rap-rap exhaust or the distinct tapping of those mechanical lifters.
Despite continued criticism from the enthusiast press for
its dismal build quality, styling eccentricities, and overall lack of finesse,
Corvette sales took a vertical leap for '69, rising by more than 10,000 units
to 38,762 -- a record that wouldn't be broken until 1976.
