1963 Grand Sport Corvette #005 Bench Racing With Corvette Engineer Bill Tower – VIDEO

Bill is a living encyclopedia of Chevrolet and Corvette R&D experience and can keep an audience enthralled with insider stories about the early days of secret performance Corvette design and development. After attending General Motors Institute (GMI) in the early 1960s, Bill was hired by Chevrolet and landed a peach of a job (abet a LOT of work!) as a Development Engineer in the Corvette Design Group.

Tower worked with, and, or knew all of the key people within the world of Corvette R&D. Needless to say, Bill has stacks of stories, insights, and understandings into what went down during the wild days with Duntov and the team. Tower was also pals with race car driver/engineer, Mark Donohue and NASCAR legend, Smokey Yunick. Read More

Vette Polls: Was There a 6th 1963 Grand Sport Corvette? Cast Your Vote!

While poking about for some background on another project, I stumbled upon a post talking about a story from Autoweek writer, William Jeanes that addressed the notion that there was a SIXTH Grand Sport Corvette. If you’ve been into the Corvette hobby for a while, you’re familiar with the GS Corvette story: Five lightweight Grand Sport Corvette race cars were secretly built by Zora Arkus-Duntov as a counter punch against the Shelby Cobras. The cars showed potential, but GM’s president, Frederick Donner, order that Chevrolet MUST comply with the official GM policy that “we DO NOT race cars.” Read More

The Duntov Files E-Book, Pt. 4: Time Machines, 1963 Grand Sport vs 1989 Trans-Am Corvette

Late in 1989 Corvette Quarterly (formerly “Corvette News”) arranged a special event. Grand Sport #002 was brought together at Sebring International Raceway for a side-by-side comparison test with the then “state-of-the-art” tube chassis Trans-Am C4 Corvette. Twenty-six-years separate the two cars, they are both tube-frame cars with replica bodies, and powered by Chevrolet engines. But that’s where the similarity ends, and the difference is startling.

Vintage Grand Sport Corvette Films from 1962 and 1963 – 2 VIDEOS

Last week while finishing up a story about Bill Tower’s Grand Sport #005 Corvette for Vette Magazine, I came across two YouTube videos posted by GM Heritage Center. The videos are silent and were probably shot with an 8mm camera that someone brought along to the events. The film looks like hand-held and amateurish and not at all the same quality of the Jam Handy films from that era. But, you do get to see the Grand Sports in action. Read More

Rene Lopez-Duprey’s 2016 Z06 Corvette Convertible- the Perfect Florida Corvette!

Rene was a happy Corvette owner, enjoying his Corvette convertible in the beautiful Florida climate. There’s nothing quite like top-down motoring in a mostly warm, sunny area. All was well, that is until the C7 Z06 came out. Rene prefers convertibles, so when he learned that the new Z06 was available as a convertible; he just had to have one. Read More

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

The C8 mid-engine Corvette is a arguably the biggest new in the world of Corvettes since the very beginning in 1953. Many of us thought Chevrolet would never offer such a Corvette, but here we are. And thanks to an established pattern of performance track-model Corvettes that started in 2001 when Chevrolet decided to brand the car, “Z06” after the one-year-only 1963 Corvette, subsequent new model Corvettes have offered a Z06 model. Within minutes after the C6, C7, and now C8 Corvettes were debuted, fans second question (after “how much is the new Vette?”) is, “Where’s the Z06?” Yes, we expect it and Chevrolet has not let us down since.

Larry Taylor’s Grand Sport Corvette #004 Replica – Videos!

When Grand Sports #003, #004, and #005 arrived in Nassau under the banner of the “Mecom Racing Team”, they were loaded for bear. This is the now classic Grand Sport look; fat racing tires on wide knockoff wheels, aggressive vented hood, and big wheel flares. And under the hoods were Duntov’s latest engine jewels, the all-aluminum 377 small-block Chevy with 58mm side-draft Weber carbs. It was a romp for the grand Sports, as the Cobras were thrashed.

Three months later, the 1964 class win at the 12 Hours of Sebring with Roger Penske at the wheel of Grand Sport #005 would be the high-water park for the Grand Sports. This time period saw extraordinary advancement in racecar technology, such that by the end of 1965, the three-year-old cars were outdated. Read More

The Tale of Two C4 Grand Sport Corvettes in a Tiny Florida Town

Lake Placid is also home to two of the rarest special edition Corvettes, a 1996 Grand Sport Coupe and Convertible. And here’s the kicker – they both reside within two blocks of one another! Ron Ellerman is the original owner of the 1996 Grand Sport Corvette Coupe and John Meyerhoff is the owner of the 1996 Grand Sport Convertible. Read More

1963 Aluminum 377 Small-Block Chevy Engine

The design parameters of Cole’s SBC were that the engine should be; small, lightweight, simple, and inexpensive. Cole reasoned that an aluminum version of the SBC using a new aluminum-silicone alloy would be obviously lighter and probably less expensive to make. To keep costs down, there would be no valve seat inserts, no pressed-in valve guide inserts, or cylinder liners. But sometimes a simple idea turns out to not be so simple.

Problems started right from the beginning. The complex molds used sand cores and the completed castings required extensive machining. Sand-cast aluminum is high in porosity and low in density. During machining, cavities would open up in the castings, causing a high rejection rate, which drove up cost. Aluminum pistons on aluminum bores were hard to lubricate and would scuff the bores. Between the strength of materials and the casting challenges, pouring aluminum into molds designed for cast iron wasn’t going to work for mass-production Read More

Doug MacDonald’s 2017 Dave MacDonald Grand Sport Tribute Corvette

In late September 1962, 16-year-old Doug MacDonald had such a defining moment. Doug’s big brother was road racing legend and 2014 National Corvette Museum Hall of Fame Inductee, Dave MacDonald. When your brother is eleven years older than you, while you are growing up, your perception is that your sibling is “one of the adults.” In 1960, Dave MacDonald started racing a 1957 Corvette when he was 23 years old and Doug was only 13, so the best Doug could do was hang around on the sidelines, take in as much as he could understand, and do his best to stay out of the way!
