Lot #1407 – 1967 Chevrolet Yenko Super Camaro 427/450 will be selling with No Reserve at our 2022 Scottsdale Auction.
One of America’s most successful racing drivers from 1957 through 1981, Canonsburg, PA-based Chevy dealer Don Yenko was one of the truest proponents of the “win on Sunday, sell on Monday” mantra during his storied career. With the Camaro’s debut in late 1966 as an eventual and more-conventional replacement for the rear-engine Corvair, Yenko immediately realized the future was with Chevrolet’s new competitor to Ford’s Mustang.
Since the early Camaro was already available with a mild 396ci “Mark IV” big-block engine, quiet factory-sanctioned experiments were conducted with Chevrolet’s larger-displacement RPO L72 427-cubic-inch mill at Bill Thomas Race Cars in California ‒ one of Chevrolet’s unofficial “Skunk Works” racing shops, before the Camaro even went on sale. Factory-rated 425 horsepower or 25 more, depending on the specific application, the solid-lifter 427 was the key to Chevrolet’s racing future in the face of Chrysler’s virtually track-ready Street HEMI and Ford’s 427 cars. Southern California’s Dana Chevrolet, led by former Shelby American national sales manager Peyton Cramer and racer Dick Guldstrand, worked with Thomas to build 427-powered Camaros. Well-known Chevy drag racer Dick Harrell, who was sponsored by Thomas, brought Chicago’s Nickey Chevrolet into a similar production deal; however, a change in business plans at Nickey led Harrell to join forces with Yenko Chevrolet, including national sponsorship for Harrell’s racing cars.
Initially named “Stomper” but soon known as the Super Camaro, Yenko’s wild 427-powered cars were rated 450 horsepower with 4-speed transmissions and 410 ponies with an automatic. The first were based on factory-original 350ci cars with much hand-labor required to complete the conversions; however, once the RPO L78 396/375hp option was available, only the short-block required swapping for a 427ci equivalent. Much more than a simple engine upgrade, Yenko’s beasts also included significant modifications to the cars, such as suspension and driveline upgrades, NHRA-legal scattershields, exhaust headers, added instruments (including tachometers), higher-grade spark plug wires, a fiberglass hood with a Corvette “Stinger” style treatment, hood pins and “427” badges.
Warren Dernoshek, one of Yenko’s mechanics, remains active in the Yenko niche and, as he related in a June 2010 Muscle Car Review magazine article, extensive handwork was required to complete the Yenko Super Camaros, noting the lack of lifts, hoists or air tools onsite at the time. Since the emphasis was obviously on refining the conversion process for speedier response to growing dealer orders once word got out, production numbers for these first-year Yenko Super Camaros understandably differ a bit among marque experts. Dernoshek was quoted at 53 cars – 22 of which were converted by Harrell at his St. Louis, Missouri, operation, while other experts cite from as few as 54 to as many as 75 such cars produced. Suffice it to say these formidable performers are exceedingly rare and sought-after by many of today’s top collectors.
Bearing Yenko serial number YS-725, this 1967 Yenko Super Camaro 427/450 – denoting 427 cubes and 450 horsepower – is documented by Camaro expert Jerry MacNeish as one of 1,138 that left the factory with an RPO L78 396/375hp V8. Following shipment to Yenko Chevrolet, it was upgraded to full Super Camaro 427/450 standard for $677.27, with a copy of a handwritten Yenko invoice on file and available for inspection listing all the many upgrades, with the car completed on July 18, 1967. YS-725 was one of five shipped on July 27, 1967, to Jay Kline Chevrolet in Minneapolis and, according to a letter on file from the original owner, he eventually sold it in November 1990 at 17,121 stated miles, with the car verified by Yenko expert Vince Emme as one of the 54 original 1967 Yenko Super Camaros in his records.
Continuing to benefit handsomely from an older restoration, subsequent owner/collectors include Gary Holub and Irwin Kroiz. Listed in the Yenko Supercar Registry, YS-725 is verified by MacNeish to retain the original VIN plate and hidden VIN cowl stamping. In addition to excellent documentation on file, this Super Camaro was inspected by Warren Dernoshek and affirmed authentic by him. An exceedingly rare and true part of Yenko history, it stands tall as pure American supercar royalty.

Here comes trouble: A Triumph TR6 with a Matchless frame
Kids are impressionable, especially when motorcycles are involved. That magical combination of sound, smell and danger has a way of imprinting itself on young minds. But Kyle Harvey didn’t just dream of bikes as a child—he practically grew up with them.
Kyle’s trade is tool and die making, but his passion is building bikes. His father, Garth Harvey, got Kyle and his brother into bikes at a young age; as soon as they could start their old man’s vintage motorcycles, they were riding them. Living in Edenvale in South Africa’s Gauteng province, the boys also had direct access to the local Classic Motorcycle Club.
The folks at the CMC made quite an impression on young Kyle—and taught him everything he knows about vintage bikes. After helping numerous friends work on their bikes, he went on to open his own shop, named simply ‘The Workshop.’ Kyle has been building and restoring classic motorcycles for over a decade now.
This cheeky bobber is his latest build, and it’s immensely fascinating. The engine’s from a Triumph TR6 Trophy, the frame is from a Matchless, and the quirky handmade details on it are endless.

The Swan Song of the V12
The V12 engine holds a special place in the heart of many automotive and motorsports fans. For some, it’s the sound of Formula 1 through the years, especially during the 1990s. For others, it’s engines like the 6.1 L BMW S70/2 from the McLaren F1 or the 3.9L Lamborghini V12 that powered all their cars from the Miura through to the Diablo. No matter where it lies in your heart, it is the “proper” configuration for many: 6 cylinders per bank, put into a V, and firing in an odd sequence to give it that special roar under power.
Yet, as concerns over fuel efficiency, qualms about environmental impact, and high-powered turbocharged V8 or V6 engines are the norm now, the V12 is slowly, but surely, being put to rest. In fact, the only place that V12s are still hanging on by the last threads of their engine mounting bolts are in supercars, hypercars, and a few ultra-luxury cars. Even then, many exotic brands have announced that their next cars will either be V10s or turbo V8s and V6s.
Since it appears that the swan song of the V12 is reaching a crescendo, we thought it only appropriate to celebrate the few remaining cars out there that carry them. It may be the last time we see some of these brands, many of which are known for their V12s.
The Amazing Last V12 Production Versions from the Big Brands

The writing is on the wall for the prancing horse, as the new Ferrari 296 GTB is showing the direction that Maranello is headed. Yet, unless you were invited to snag one of the limited-edition Monza SP1 or SP2 cars, there is still one car you can buy from the legendary marque that has all 12 cylinders fully intact.

The 6.5L F140 GA 65-degree V12 in the front of the 812 is the last road-going version of the V12 that debuted in the Ferrari Enzo. Producing a monstrous 789 HP and 530 lbs-ft of torque, it is no slouch either, as when the 812 Superfast debuted, it was the most powerful naturally aspirated production car engine ever made.
It has the typical low-rev Ferrari roar that rises into a howl as the car revs up to nearly 9,000 RPM, and will catapult the 3,845 (1,744 kg) car to 60 MPH in 2.9 seconds. As far as a curtain call is concerned, that’s a great way to bow out and focus on hybrids and turbocharged engines.

Mercedes-Benz used to be at the very top of the V12 pecking order when it came to luxury performance cars. Such classics as the S 65 AMG from the mid-2000s and the 500 TE AMG W123 Touring from the very end of the 1970s came with big V12s that sound astounding, but the biggest and baddest of the Mercedes V12s left on in a production car is the M279 E60 LA that hauled the S65 AMGs of 2014.

Road Tested: Gear from Shoei, Akin Moto and Rev’It!
In our continuing quest to source motorcycle gear that combines safety and style, we bring you our thoughts on Shoei’s new ECE 22.06-approved NXR2 helmet. Plus a stealthy riding parka from Akin Moto, and the perfect pair of urban riding gloves from Rev’It!.
Shoei NXR2 helmet It’s no secret that I’m a huge fan of Shoei’s helmets. Every Shoei I’ve owned has fit and felt right from the first wear, with no major deviations in their sizing or shape from model to model. So when I was looking for a do-it-all street helmet to replace my well-used Shoei RYD, the new NXR2 was a no-brainer… and it hasn’t disappointed.
I loved the RYD for its combination of neutral styling, comfort and ventilation. The NXR2 basically feels like a premium version of the RYD; it has the same clean aesthetic, but ramps up the performance. And it’s one of the few helmets that meet with Europe’s new, and more stringent, ECE 22.06 standard.
