Z06 Corvette History, Pt 1 – The 1963 Z06 Racer Kit

For “Off Road” Use Only” was Chevy Code for RACING!

Dateline: 8.12.17 / Photos: WikiCommons, Illustrations by K. Scott Teeters – When I was a wee lad and would see the term, “For Off Road Use Only” I used to think, “Well who drives these cars in the dirt and grass?” What I didn’t understand was that the term is code for “RACING”! Beginning in 1957, Chevrolet’s new general manager, Ed Cole, made the command decision that he would let “customers” carry the Corvette racing mantle by offering Chevrolet-engineered parts, specifically designed for racing, available through the Chevrolet Parts Department.

For decades, Zora Arkus-Duntov has been credited for the implementation of the Corvette “Racer Kits” through the RPO (Regular Production Option) system. Zora was the face of the unofficial Corvette racing effort, but while researching C1 Corvette chassis design, I came across some interesting information in Karl Ludvigsen’s 2014 book, “CORVETTE: America’s Star Spangled Sports Car”. While Duntov was definitely the front man, Ed Cole also charged three-time Indy 500 winner and engineer, Mauri Rose with the development of the Corvette’s RPO parts program. So, the Corvette “Off Road” RPO effort guided by Le Mans racer and class winner, Duntov, AND Mauri Rose, the second man to win the Indy 500 three times (1941, 1947, and 1948)! Pretty cool, huh?

The Racer Kits weren’t a “secret” but unless customers were tuned into racing, most weren’t aware of this special program. In truth, since improvements in suspension and brakes were for racing, customers rarely used them for their street Corvettes. And typically racers used the expensive dual quad or Fuel Injection performance engines. The Racer Kit RPO option program enabled Corvette racers to be seriously competitive in SCCA racing such that by the end of the 1950s, Corvettes were a force to be reckoned with.

Engineer Maurice Olley designed the chassis and suspension of the first Corvette in 1952 and was considered to be the best suspension and chassis engineer in Detroit. It is essential to remember that the Corvette was NOT designed to be a racecar. Continue reading

1961 Chevrolet Corvette Special – Dave MacDonald and Jim Simpson

The First Independent Purpose-Built Corvette Race Car

1961-chevrolet-corvette-sketch-side-viewThe Corvette Racing Team has proven that the Corvette is more than a match for any sports car on the planet. But in the early days, racing a production Corvette would only get you so far. To get to the next level, “purpose-built” race cars were the order of the day. Tube frames (aka “bird cages”) with a thin fiberglass or aluminum body were super lightweight and the low power-to-weight ratio made for a race car that was a handful.

Dave MacDonald was one of the young lions of Southern California sports car racing. He was a natural and quickly earned the nickname, “Master of the Oversteer.” Dave and his racing partner Jim Simpson started racing in 1960 and in their first year won 3 out of 15 races and never finished lower than 4th. In his second year Dave racked up 15 wins and three 2nd place finishes in 24 races and was on his way to being a dominant force. But like all racers, Dave and Jim wanted to move up into something faster. It was Carroll Shelby who suggested the guys get a Max Balchowsky chassis and build a purpose-built car.

Dave MacDonald Inducted Into National Corvette Museum Hall of Fame

Corvette Racing Legend, Dave MacDonald Inducted Into National Corvette Museum Hall of Fame

NCM-macdonaldDateline: 9-27-14 Auto racing legend Dave MacDonald was inducted into The National Corvette Museum Hall of Fame on August 28, 2014, in Bowling Green, Kentucky. MacDonald’s induction took place 50 years after the extremely talented young driver was tragically killed in his rookie race at the 1964 Indy 500 that also claimed the life of driver Eddie Sachs. After the race, an investigation determined that there was, “No driver error.”

MacDonald learned his driving skills in Southern California behind the wheel of several championship-winning first generation Corvettes. A gentle, quiet family man off the track, MacDonald was known as “The Master of Oversteer” and a fierce competitor. His driving skills were such that they attracted the attention of two other legends in auto racing of that time, Corvette Chief Engineer Zora Arkus-Duntov and Carroll Shelby. MacDonald drove prototype test cars for Duntov and was eventually hired by Shelby to drive Cobras professionally.

His induction into The National Corvette Museum’s Hall of Fame was well deserved and more than a little overdue. Regardless, Dave MacDonald now has a prominent and permanent place in Corvette history.

I have written extensively about the life and times of Dave MacDonald and have had the pleasure of getting to know the MacDonald family. I have Dave MacDonald’s younger brother Doug to thank. Many years ago I created a piece of line art for VETTE Magazine as a column filler “spot art” illustration. Later I included the illustration as an art print on my IllustratedCorvetteSeries.com website and mistakenly titled the print, “Dave MacDonald’s 1961 Corvette Racer.”

The 2014 National Corvette Museum's Hall of Fame inductees included: Race Car Driver Dave MacDonald, Corvette Engineer and Race Car Driver John Heinricy, and Automotive Journalist & Author, Jerry Burton.

It’s been a pleasure to get to know the family of Corvette racer Dave MacDonald. The April 2012 issue of VETTE Magazine has part 1 of my story about the career of MacDonald and the May 2012 has part 2, the conclusion. While pictures and words are great, video just adds some dimension. So, I thought some vintage MacDonald videos were in order.

MacDonald’s racing career path was similar to John Greenwood’s, in that like Greenwood, MacDonald started out in drag racing. But like many guys that like to drive Corvettes in, shall we say, a “spirited” way, it didn’t take MacDonald long to get used to not only thundering down the straight-aways, but sliding the back end around the corners. MacDonald was known as “the master of the oversteer” and his tail-out driving style was very popular with the spectators.

Back in the day, there was little-to-no video coverage of motorsports, so what we have are essentially home movies. Sometimes the manufacturers would produce promotional movies, Continue reading “Vette Videos: The Great Dave MacDonald In Action!”

Dave MacDonald:  Corvette Racer… Corvette Man… Family Man

Here’s Dave MacDonald next to his purpose-built MacDonald/Simpson 1961 Corvette Special, looking a lot like Johnny Unitas, the pro football quarterback great.

Could there have been a more exciting time and place to be into cars than Southern California in the 1950s? Probably not. It was postwar America, California only had about 1/3 its current population, Rock’n Roll was in its infancy, and the car culture was revving up. El Monte was just a  semi-rural community in Los Angeles County, the perfect place for young Dave MacDonald and legions of other guys to pour their hearts and souls into cars. What’a time!

MacDonald’s Professional Racing Career

Dave’s first car was a fast 1953 Cadillac. But when Chevy put the small-block 265 into the ‘55 Corvette, 19-year old MacDonald had to have one. He saved his money and a year later, bought his first Corvette, a Gypsy Red ‘55 Corvette. The Caddy was fast and Dave did some street racing with the car, but it was the Corvette that got him into drag racing and eventually road racing. In February 1960, MacDonald had his first official “ride” as team driver for Don Steves Chevrolet at Willow Springs Raceway, and won the Sunday main event. In his first year, Dave entered 15 regional races, taking 1st place in three events, three second place wins, and 4 third place wins. Very impressive for his rookie year.

1961, was even better. MacDonald entered 20 races, won 13 victories, and three second place finishes.  Dave’s last win of the year was in his purpose-built, tube frame, lightweight Corvette Special. This car is a story unto itself. 1962 was the year the spotlight really shown on MacDonald. While he didn’t totally dominate the year, he did finish on the podium in 16 races, including 10 victories.  It’s also worth noting that MacDonald won every race entered from early February to June – seven wins in a row. The first three wins were with the lightweight Corvette Special. After that, the lightweight car only raced two more times. MacDonald had one race behind the wheel of another lightweight tube frame car, a Devin Corvette that provided Dave with a second place win.

Dave MacDonald – “The Master of Oversteer”

“I think Dave had more raw talent probably than any race driver I ever saw.” – Carroll Shelby

The original Grand Sport Corvette is considered by many to be the ultimate “could have been” Corvette. Well, when it comes to drivers that raced and loved Corvettes, El Monte, California race car driver, Dave MacDonald is arguably the greatest “could have been” Corvette race car driver. That’s not just my opinion – that’s what I learned from researching Dave MacDonald’s racing career, from his contemporaries. Many drivers and team owners from Dave’s day are on record stating that had Dave’s life not been cut short at the ‘64 Indy 500, he would have likely been one of the greats. MacDonald’s shining star was about to go super nova!


Here’s the signature-style MacDonald rear-wheel-drift.

While I was familiar with Dave MacDonald from books in my Corvette library, it wasn’t until I started researching Dave’s background while working on a story for VETTE Magazine that I learned what a terrific guy he was. If you look in your Corvette books that have chapters covering the early ‘60s road racing scene, look for the “00” Corvette with the tail hanging out. That’s Dave “The Master of Oversteer” MacDonald.
