ome might say 1970 was a monumental year for rock music, and much of it not good. Janis Joplin and Jimi Hendrix both died at the age of 27, and the Beatles called it quits due to musical differences between Paul McCartney and John Lennon. Both continued on a musical path to highly successfully solo careers. Joplin and Hendrix–not so much. With the two most famous Beatles going their separate ways, their fans followed suit; some took the Lennon train, while others aligned with McCartney.
Muscle car fans may not have given the music industry much thought at the time, nor did GM have a clue about an upcoming oil crisis that was a mere three years away, so the ’70 Chevelle came off the assembly line flexing every bit of its muscle-bound demeanor. Although on the same chassis as the ’69, the sheetmetal and exterior features were revised with new design elements to give it a more powerful posture. That attitude also carried on into the interior, which possessed a no-nonsense sporty theme. As usual, various engine combinations were available, including the beefy 454ci mill rated at 360 hp.
With all the horror stories that tend to follow cars purchased via online auctions, Tony found an exceptional stock example in Houston, but that didn’t stop him from tearing the car down and putting his own touch on it. “I’ve always had a vision of building a car with a somewhat stock appearance and a ton of horsepower,” Tony confesses.
A Holley 1,150-cfm Gen 3 Dominator carburetor feeds the polished Edelbrock intake while a custom set of Muffler Man headers encourage greenhouse through a 3-inch stainless exhaust and Muffler Man mufflers. Take it from this here writer, the sound of this beast is something to behold–it’s an absolute attention-grabber.
The rear suspension consists of QA1 coilover shocks and 150-pound springs. Up front a pair of QA1 coilover shocks and 300-pound springs mate to the stock control arms. Wilwood 13-inch rotors and four-piston calipers were assigned stopping duties on all four corners and a Wilwood master cylinder and Hydro-Boost system issue smooth pedal performance.
American Racing Torq Thrust wheels fall in line with the Chevelle’s vintage ’70s vibe and keep Tony’s time capsule in the preferred decade. A slight departure from the smaller 15s, a set of 17×8 wheels reside up front sheathed in 255/45R17 Nittos, while out back a set of 18x10s are wrapped in 305/45R18 Nitto rubber.
When it came time for a paint and body refresher, Tony sent the car off to Kenny Pfitzer at Kenny Pfitzer Designs in nearby Corona, California. Pfitzer massaged the sheetmetal to a smooth foundation prior to applying multi layers of PPG Fathom Blue paint and deep clearcoat.
“Running a big-block is one of my favorite aspects of the car. It confirms its original spirit,” Tony says. “I could have gone with an LS engine and gotten better gas mileage, but this car feeds off the looks and sound of a burley big-block. Besides, the neck-snapping torque makes this thing a blast to drive.” And drive it he does. Tony is a staple at SoCal’s Quarantine Cruise, where his killer Chevelle always draws a crowd. “It’s great to be one of the original crew, and because of that event and this car, I’ve made a lot of new gearhead friends,” Tony mentions.
The project was a two-year on-and-off gestation that, according to Tony, would still be ongoing without the help of Pfitzer and Mike Hayden at Hayden Motor Sports in Fallbrook. “I can’t thank those guys enough for stepping up to help get this project on the road,” Tony relays.
