Chevy’s Secret Duntov Engines Hot Rod Mag E-Book

Duntov’s Dec 1967 Hot Rod Magazine Cover Story; Secret Exotic Chevy Engines

Car magazines were my friends when I was a young teenager in the late ’60s. While I was crazy about Corvettes, there were no road racing tracks, only a drag strip close to where I lived in Collingswood, New Jersey. So, if I wanted some racing action, the drags was it; which was fine by me because tire-burning muscle cars regularly roamed the streets of our town, and were SO COOL.

Zora and his brother, Yura were making and selling their Ardun hemi-head conversion kits for flat-head Fords in the early 1950s.

Hi-Performance CARS, Popular Hot Rodding, Car Craft, Car and Driver, Car Life, and Hot Rod Magazine were my favorite flavors for fun reading. But somehow, the December 1967 issue of Hot Rod got past me, as I did not see that issue until way after eBay sellers started selling them 20 years ago. Recently I picked up a copy to add to my Corvette library.

The BIG SPLASH is the cover! There was Zora on the cover of Hot Rod, in a corporate gray suit, white shirt, a narrow black tie, and all smiles; but then again, Zora never knew a camera he didn’t like. And why wouldn’t he have been a happy guy, sitting there with four exotic experimental Chevrolet engines; single-overhead cam heads, and double-overhead cam heads with fuel injection systems of different configurations. Duntov even pushed to offer a SOHC kit for small-block Chevy engines via the Chevrolet Parts Catalog! Imagine that under the hood of your Vette!

Hot Rod’s editor, Jim McFarland got the plum assignment to go to Detroit with a recorder and interview Duntov about “some” of the experimental engines Chevrolet engineers were playing with. After the sixth paragraph, McFarland turns over the mic to Zora to take it from there. Duntov was very exacting and articulate in explaining everything he was allowed to talk about. Zora may have been the ultimate corporate misfit in his time, but he knew when to stop talking.

Here’s Zora and Jim McFarland many years after the famous Hot Rod Magazine “Inside Chevy’s Secret Engines!” December 1967 cover story.

The article is a fascinating peek inside the thinking of Chevrolet performance engineers, circa 1967. Enjoy! – Scott

1963 Fuelie Corvette vs 1967 L71 427/435 Corvette – Videos

Performance Bookends of the Shortest Generation Corvette, the C2 Mid-Year
Dateline: 6.23.17 – The difference between a 1962 and 1963 Corvette is staggering. In 1963, the new Sting Ray looks like the sports car from another planet! The only carryover components used for the new Corvette were the base and optional engines. Everything else (body, interior, suspension, and frame) was all-new. The C1’s basic structure was created in 1952, and over the years was given slight tweaks, such that by the late 1950s, the Corvette was holding on against the European cars. But the new Sting Ray was a game-changer.
We’re going to look back at the first and last “performance” Corvettes – the 1963 Fuelie and the 1967 L71 427/435. The Sting Ray had an all-new parameter frame that would ultimately serve as the foundation of the Corvette up to 1982! The new C2 frame allowed the passenger seats to be located “down and inside” the frame rails, unlike the C1’s frame that located the seats “on top” of the frame, thus allowing the overall design to be lower and more slender. Although the shape looked “aerodynamic, it suffered from severe “lift” at high speeds. The lift issue was a combination of the body shape, and the rear suspension “squat” upon hard acceleration – and was never really solved, just dealt with.
The independent rear suspension and updated front suspension made the 1963 Corvette the only American car with four-wheel, independent suspension. This was a very BIG deal then. The new interior was just beautiful. The dash had double-arches with a perfectly laid out array of the proper sports car gauges. From 1953 to 1962, the Corvette was a convertible with an optional bolt-on hardtop. The new Sting Ray was a production of Bill Mitchell’s 1959 Stingray Racer – a beautiful car with big aerodynamic problems. Instead of a convertible-only version, there was a coupe version with the now classic “stinger” design. The hidden headlights were show-car-like, and rotated horizontally along the front leading edge when the lights were turned on.

The rear glass had a split down the middle so that the crease that started at the front edge of the roof could run uninterrupted back to the end of the car. This was the infamous “split-window” that was a love-it, or hate-it detail and was Bill Mitchell’s pet design element. The split-window was gone after 1963 – making the 1963 coupes a rarity. 1963 convertibles outsold coupes, 10,919 to 10,594. Some coupe owners replaced their split-window with a 1964-1967-style rear glass! Continue reading

The POWER of the Corvette

From the Blue-Flame Six to the Mighty LS9,

a Salute to Corvette Engines

Check out the SLIDE SHOW at the bottom of this post!!!

If you are new to the Corvette hobby, it’s hard to realize that 57 years ago the car began as a 150-HP beauty queen, made from a new and exotic material called “fiberglass,” available in any color, so long as it was white. As soon as Duntov could get his “magic hands” on the first small-block Chevy, the party began. Dual quads showed up right away and before we knew it, in ‘57 we had a fuel-injected Corvette. Take that! European exotics! F.I. is common today, but back then, wow, that was American-style autoexotic.

Corvette engines all have a story – small-blocks, big-blocks, the new LS series engines. Continue reading “The POWER of the Corvette”

Corvette Engines As Miniature Automotive “Art”

Note the quarter on the display base for scale.

Modern high-performance engines are just amazing machines. A quick look at the most powerful production engine to ever come out of Detroit is the supercharged LS9 ZR1 Corvette engine. This 376-cubic-inch engine has a Net horsepower rating of 638-HP. Measured in the old “gross” power rating system and the number would be easily be in the low 700-HP range. The ZR1 and it’s little brother the 505-HP Z06 can easily smoke ANYTHING from the old glory days of the stump puller muscle car era and get double the gas mileage to boot!

But this isn’t about numbers, it’s about aesthetics. Take the plastic or carbon fiber covers off on any LS-powered Corvette and you’re greeting with a maze of complicated hardware. I guess I’m “old school,” but I enjoy looking at old, pre-smog control device muscle car and racing engines. The simplicity of those old mills was oftentimes “art.” Continue reading “Stunning Die-Cast Corvette Engine Models”
