Frank Antonaccio’s 1966 Corvette

rank Antonaccio’s background as a retired auto technician has afforded him the knowledge and expertise making him proficient at restoring classic cars. He’s also no stranger to vintage Corvettes as he’s done three to four stock restorations, but when he came across this 1966 Corvette he decided to take a different approach and create a restomod tribute to the legendary Sunoco Penske racing Corvettes.




When he purchased the car, it was far from being in pristine condition. It had small flares in the front fenders, oversized rear fender cuts for larger tires, shoddy bodywork, and even a mismatched 1967 nose. However, it was those imperfections that made it the perfect candidate for his Sunoco tribute project, which was inspired by the real Penske Corvette he saw at the Corvettes at Carlisle event.
Once Frank pulled the body off the frame it was revealed that the car was hit so hard the firewall below the heater box was cracked, the tunnel area near the gas pedal was damaged, and the frame was bent as well. Working at a GM dealership, Frank had access to a frame machine and was able to get things straightened out to lay a foundation for the transformation to come.
Underhood, Frank chose a Mark IV Chevrolet 427ci big-block. The engine features a compression ratio of 10.25:1, a Comp 11-602-4 hydraulic flat-tappet camshaft with 0.522/0.507 lift, and stock cast-iron cylinder heads. For induction, he installed an Edelbrock C396 intake manifold paired with a Holley 750-cfm carburetor. The exhaust system includes Doug’s Headers and matching side pipes, delivering an unmistakable rumble. A Cold Case aluminum radiator, PerTronix ignition, and GM high-flow water pump ensure the engine stays cool and reliable, especially during spirited drives. With meticulous attention to detail, Frank achieved a setup that produces approximately 450 hp and 460 lb-ft of torque.

The suspension retains its stock configuration, with new springs and rebuilt upper and lower ball joints for improved handling. Frank also rebuilt the original steering box to ensure responsive control. The brakes, restored by Lonestar Caliper Company, remain true to the factory setup, providing dependable stopping power.
One of the most challenging aspects of the build was obtaining the perfect “Sunoco Blue” paint. With no official color code available, Frank embarked on a months-long quest. “I tried ‘Pepsi Blue,’ but it was too light. I did several spray-outs with different mixes, but nothing worked,” Frank says. After spending $240 on failed attempts, he finally struck gold.
An Internet search led him to a story about Roger Penske’s body shop restoring the “Blue Hilton,” the transporter truck used for Penske’s race cars in the 1970s. On a last-ditch effort, Frank reached out to the Penske Collision Center in Fort Wayne, Indiana, and was able to reach the body shop manager to explain his dilemma. The shop manager explained they also had a difficult time finding just the right mix. Through PPG they were able to come up with the right color formula and shared with Frank the correct “Sunoco Blue” paint code. “I spent three months and multiple trips to the paint store searching for just the right color, Frank says. “As a running joke, when I would walk through the paint store doors the counter guys would say, ‘Uh oh, here comes Frank again.’




Frank chose American Racing Torq Thrust D wheels, sized 15×7 in the front and 15×8 in the rear and wrapped them in Mickey Thompson rubber (235/60-R15 in the front and 255/60-R15 in the rear), giving the Corvette that race-inspired, period-correct look.
Inside, Frank kept the interior true to its factory design, with one notable exception: a shortened Hurst shifter lever, reflecting a modification performed during the time for quicker and more precise shifting. The combination of the restored interior and the powerful drivetrain creates an authentic 1960s performance driving experience.

Frank’s 1966 Corvette Sunoco tribute is a testament to his skill, dedication, and love for classic cars. From overcoming structural damage to tracking down the perfect paint color, every step of the process reflects his commitment to getting the car “just right.” The result is a stunning restomod that pays homage to racing history while turning heads on the street.
