1963 Aluminum 377 Small-Block Chevy Engine

Published on by Scott

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

Corvette Chiefs, Pt. 1 of 5 – Zora Arkus-Duntov, Corvette’s Nostradamus

Published on by Scott

As a young man, Duntov was into boxing, motorcycles, fast cars, and pretty girls. After his formal engineering training in Berlin, Germany, Duntov started racing cars and applying his engineering skills to racecar construction. In 1935 Duntov built his first racecar with help from his racing partner Asia Orley; they called the car, “Arkus”. Their goal was to debut the car at the Grand Prix de Picardie in June 1935. But after a series of mishaps, the car caught fire and never raced. From this point forward, all Duntov wanted to do was build racecars. Read More

Corvette Factory Show Cars 1961 Mako Shark-I, Part 2 – VIDEO

Published on by Scott

Larry Shinoda was Mitchell’s preferred, go-to stylist guy and seemed to be the best at pulling Bill’s ideas into reality. According to Peter Brock (National Corvette Museum 2017 Hall of Fame inductee), Mitchell was just as tough as Earl, but more jovial and at times profane. Bill just wanted to be “one of the guys”, but he knew what he wanted. (Brock’s book, “Corvette Sting Ray: Genesis of an American Icon” is a MUST READ for all second generation Corvette fans.) Since Larry Shinoda worked out the translation of Brock’s Q-Corvette design into the Stingray Racer, Larry was tasked to do the XP-755, “Mako Shark”. Larry was also working on the XP-720, the 1963 Sting Ray, in its development phase. Read More

Corvette Factory Show Cars, Part 1 -1958 XP-700 Corvette

Published on by Scott

The XP-700 was built on a 1958 283 Fuelie Corvette. In 1950s excess style, everything is “bigger and better”. The front was pure “custom car design” with an elongated, elliptical nose and a scoop under it. Mitchell wanted to break away from the Earl driven, big toothy grille, towards something slim and lightweight. The now-classic Dayton Knock-Off Wire Wheels were part of the effort to make the car look lighter. The Lucas spotlight headlights are moved forward and also had scoops under them. The recessed hood vents showed up on the 1963 Corvette, but with fake grille inserts, and the 1964 Corvette, sans the grilles. The front fender scoops were shorter versions of the production 1956-1957 fender scoops. Read More

Corvette’s Founding Fathers, Larry Shinoda, Pt 5 of 6: Sting Ray & Mako Shark Designer

Published on by Scott

Larry Shinoda was the perfect designer/stylist for GM VP of Styling Bill Mitchell. In the same way that Mitchell fit with Harley Earl, Shinoda clearly understood what Mitchell wanted. As VP of Design, Mitchell’s job was to hold the vision for what he knew would be new and fresh, then lead his designers and stylists to bring his vision into reality. Corvettes were always Mitchell’s pet projects and he was famous for saying, “Don’t get cocky, kid! I design Corvettes around here!” Mitchell’s Corvettes were about design, speed, power, and performance. And for that, he needed a designer/stylist equal to Duntov’s engineering/racing prowess. Larry Shinoda was his man. Read More

Founding Fathers Pt 3 of 6: Bill Mitchell, Creator of the Corvette Look

Published on by Scott

A few years before his death in 1988, Mitchell has this to say about the C4 Corvette, “That square box is pretty near plastic… the instrument panel – Dracula’s dressing room… it rides like a truck… it isn’t a style car, it’s an machine car… engineers are running it. Earl would never let that – I would never let that happen, and I condemn the guys for it!” Read More

The History of Mid-Engine Corvettes, 1960 to C8: Part 2

Published on by Scott

But at the height of the Corvair’s popularity, V.P. of Design, Bill Mitchell saw “potential” in the Corvair’s unique platform and set two of his sharpest designers to work on a radical Corvair; Larry Shinoda and Tony Lapine. Two cars were built; the Monza GT was a mid-engine coupe and the Monza SS was a rear-engine open-roadster. Neither car looked like anything else on the road, let alone a Corvair. If you ever wondered where the big front fender humps on the Mako Shark-II came from, now you know! Read More

George Haddad’s Re-Creation 1969 427 ZL-1 Corvette

Published on by Scott

To understand the importance and uniqueness of George Haddad’s 1969 ZL-1 Corvette, we have to get into the “Vette Vues Time Machine” and go back to late 1968. The December 1968 issue of Hot Rod Magazine hit the newsstands like a thunder clap, with an obviously all-aluminum big-block 427 Corvette engine wearing bright yellow tube headers. It looked like Chevrolet finally had an ace trump card. The 427 ZL-1 was the ultimate “pie-in-the-sky” Corvette setup – big-block horsepower and torque – with the weight of an iron small-block! Duntov was a happy man because his dream of an all-aluminum engine for the Corvette went all the way back to the 1957 Q-Corvette concept that not only called for a fuel-injected all-aluminum small-block engine, but a trans-axle! (Sounds like a C5, doesn’t it?) Read More
