It is said that when you find something that works, don’t change it.  For Chevrolet, this sentiment resonated amongst the senior designers of the Corvette.  Despite the conceptual changes that Bill Mitchell had been toying with since 1958, the reality was that the Corvette was going to be around in it’s current form for a few more years.  From a sales standpoint, this seemed to sit just fine with GM executives, who had watched the Corvette’s financial successes gain more ground with each passing year.  Even in 1958, when an economic recession impacted so many manufacturers, the Corvette had succeeded in turning a profit.  Surely, the Corvette still had room to grow - even if that growth meant staying the same.

1960 Corvette Overview

While steel-belted tires are common today, back in the 1950's, they were unheard of.  In fact, the 1960 Corvette was the first Corvette to use Nylon Belted Tires (a type of tire that is still sometimes used today, though not as durable as a steel belted tire).

Prior to 1960, the Corvette (along with most other production cars), used cotton ply tires.  A "cotton ply" was the cross layering of cotton fabric on the interior of a tire to provide adequate wall strength to hold the pressurized air when the tire was inflated.

And from 1959 to 1960, stay the same it did.  From a design standpoint at least, the 1960 Corvette is virtually indistinguishable from the 1959.  The body lines and chrome trim is nearly identical on both models.  The interiors have virtually no distinguishable differences.  In short, the 1960 Corvette was, from all design purposes, a continuation of the 1959 production model.

However - the engineers behind the power plant that gave the Corvette it’s heart and soul had something new in mind for the 1960 model year.  The top two engines, both fuel injected or “fuelie” engines, received an increase in their overall horsepower.  The addition of solid lifters and a higher, 11.0:1 compression ratio boosted the strongest of the fuelie engines to 315-bhp at 6,200 rpms.  The second most powerful engine included hydraulic lifters (which made for easier maintenance) and pumped out an impressive 275-bhp at 5,200 rpms.  Because of these performance increases, the Powerglide automatic transmission was no longer an option, as it simply could not handle the torque these new powerhouse engines generated. 
Although Chevrolet shied away from advertising the Corvette as a performance car after a ban on racing had been put into place by the Automotive Manufacturers Association ( or “AMA” for short), Chevrolet continued to offer many performance options for the 1960 model year.  Aside from the optional, “beefed up”, 315 horsepower engine which carried an additional cost of $484.20, there was also the option of ordering Positraction for $43.05 and a four-speed gearbox for $188.30.    Additionally, the metallic brake linings were again made available as a $26.90 option. 

Whereas a few short years ago the Corvette was railed by critics for it’s lack of performance, the Corvette had come into it’s own as a genuine sports car both in the United States as well as around the world.   It’s on road abilities were no longer questioned.  It had been accepted as a serious contender in many racing circuits, despite the decision made by the AMA.  In fact, 1960 saw three Corvettes run at the famous “24 Hours of Le Mans”.  Owned by yachtsman and one-time car builder Briggs Cunningham, the Corvette proved it’s mettle against some of the staunchest competitors in the world.  Drivers Bob Grossman and John Fitch drove one of these Corvettes to a respectable eighth place overall finish.  Considering that this Corvette was

was privately owned without formal manufacturer’s support and that it was competing against factory racing prototypes from some of Europe’s most illustrious manufacturers, it makes the measure of their success that much greater.

After the run at LeMans, where Cunningham’s Corvette achieved a top speed of 151 miles per hour down the Mulsanne Straight, Chevrolet began to offer Cunningham cylinder heads cast from a high-silicon aluminum alloy.  The heads, (based on a design that was first introduced to the 1957 Sebring Corvette SS prototype racer,) maintained the stock 11.0:1 compression ratio but featured improved intake and exhaust flow.   Although the use of aluminum heads was fine in theory, the reality of these heads were that they tended to warp if the engine overheated.  Further, Chevrolet had quality control issues with the castings used to create these aluminum heads.   The belief is that these heads, which provided proven performance, were never made available to retail customers.

The on-going debate about a second generation Corvette continued to be a topic of much discussion throughout 1960.  However, unlike previous years where prototype designs and rumored modeling ended up abandoned without the funding to become anything more than design sketches or clay models, 1960 saw the debut of a dramatic, new special edition Corvette called simply “Stingray” that was “privately” campaigned by GM Design Chief Bill Mitchell.  The fact alone that Bill Mitchell had succeeded Harley Earl’s position upon his retirement in 1958 led many Corvette enthusiasts to believe that this “track edition” Stingray Corvette would guide the shape of things to come.

In addition to the dramatic, bold look of the Stingray, Mitchell also continued to work on breathing new life into the existing Corvette styling, which had gone virtually unchanged since 1956.   However, despite an abundance of design ideas from the team of designers in his studios, the Corvette would continue to remain mostly unchanged until 1962.   While individuals like Mitchell were envisioning a new Corvette on the horizon, Chevrolet had it’s priorities set on other ventures, including the Corvair.

Although Ed Cole’s technically advanced, compact Corvair was considered one of the most interesting of the Big Three’s new 1960 small cars, it was plagued with service issues including: oil leaks, thrown fan belts and tuning difficulties, amongst others.   When it failed to outsell the Ford Falcon that same year, General Motors allocated money be put aside to fund other, more conventional compact cars, which would ultimately cut into the development dollars that could/would be spent on developing another Corvette.  For now, the Corvette would have to continue to weather on in it’s current form.

And weather on it did.  In 1960, Corvette overcame the sales hurdle that had eluded it for so many years - it sold more than 10,000 units that year.  In fact, 10,261 Corvettes were sold in 1960, braking the psychologically important “10K” barrier and making it the most successful Corvette (from both a performance and a sales standpoint) yet.   Corvette had proved itself to the General Motors executives and it’s long term future was most definitely assured.

In 1960, Bill Mitchell and Zora Arkus-Duntov developed the Stingray Special, a "one-off" racecar that had evolved from the earlier 1957 Corvette Super Sport.

Specifically designed for the racetrack, the Stingray Special included a fuel injected 283c.i. V-8 engine that produced 315 horsepower and operated at a compression ratio of 10:1.

It has been reported that Dr. Dick Thompson, one of SCCA's (Sports Car Club of America) top Corvette competitors of the day, dropped by "Studio X" (Special Projects area of the GM Tech Center in Warren, Michigan), took one look at the new racecar, and promptly promised to drive it in C-Modified events (one of the modified classes in the "SCCA National Sports Car Championships".)

To everyone's astonishment, not only did the Corvette Stingray Special successfully compete with some of Europe's most respected sports cars, but in its inaugural (and only) season, Thompson won the SCCA National Championship that same year.

The carbureted engines that were also included as optional engines for the 1960 model remained the same as they had on earlier models.  The most conservative of these engines was a 230 horsepower engine that included a single, four-barrel carburetor.  Next in succession of horsepower was a 245-bhp, hydraulic lifter version of the same engine that included a dual-quad carburetor.  Topping these was the 270-bhp engine with twin four-barrel carburetors.
The refinements to the 1960 Corvette did not end with the engine.  In 1956, Zora Arkus-Duntov developed the “Duntov Cam”, a high lift camshaft that was intended to help make Corvette a contender in the international racing circuit.  While this cam proved most effective in generating the extra performance necessary to produce a car capable of winning against the staunchest of competitors, it also caused engine temperatures to rise far above similar engines with more conventional cams.  To compensate for this, aluminum radiators were introduced in the 1960 Corvettes for anyone ordering a Corvette with the Duntov Cam option.  Aluminum clutch housings for the manual transmissions were also introduced, which helped to drop the Corvette’s overall weight by eighteen pounds (18lbs).  A power-saving, thermostatically controlled cooling fan was introduced as a new option, as was a long range, 24 gallon fuel tank.  

Standard options for the 1960 Corvette included the introduction of a larger-diameter front anti-roll bar matched and a new, heavier duty rear bar.  These changes, plus an extra inch of rear-wheel travel in rebound produced a smoother riding, more neutral handling Corvette than ever before. on Facebook on Twitter
