462 ci ’67 GTO

For many the term GTO first entered our vocabulary in September ’63 when Pontiac introduced us to the Tempest-based 389 Tri-Powered Le Mans. PMD was already using the infamous French 24-hour race, why not subjugate the term GTO? In fact, Ferrari was the first to use the GTO moniker on their 1962 250 GTO Gran Turismo Omologato or, Grand Touring Homologated in English. And there was no licensing royalty to pay because geographic names are generally used without licensing as is the term GTO.  Before the bosses even knew, Pontiac had sold 5,000 GT0s   

Inspired by input from Steve Strope of Pure Vision Design, designer Eric Brockmeyer penned the sketches from which Mick Walker’s ‘67 GTO was built.

Fast forward 60 years and Nick Walker of Corona, CA approached Steve Strope of Pure Vision Design, Simi Valley, CA to build him a modern classic. Pontiac had already made some changes for the ’67 model including boring the 389 to a healthy 400 cubes and replacing the Tri-Power with a single Rochester Quadrajet 4-bbl. 

Steve, however, had something even more outrageous in mind and went to Penta Motorsports, Newbury Park, CA. Penta specialize in big-bore Ponchos, and Steve wanted a 462 cubic inch engine. Yes, four sixty-two. Penta bored and stroked a 400 incher and added Edelbrock heads, intake, fuel rails, valve covers, and their high-flow water pump along with Holley distributor, coil, and Terminator X Efi. 

While the engine was being assembled the rolling shell went out to Mick’s Paint in Pomona, CA where Mick Jenkins’ team stripped it to bare bones for a complete, body off, frame-to-decklid repaint that entailed lots of detail work including smoothing out the firewall and inner fenders, tucking the bumpers, and installing Pontiac Grand Prix flush door handles. For the color Steve chose a 2024 Lamborghini Urus hue called Blu Astraeus Metallic applied by Fernando Hernandez.

Stock chassis was upgraded with Detroit Steel tubular upper A-arms, JRi shocks and Baer brakes. In the rear is a Gear FX Ford 8.8.

While the body was undergoing restoration at Mick’s the chassis was upgraded with the addition of Detroit Speed suspension complete with tubular upper control arms, JRi shocks and Baer brakes. Out back there’s a Gear FX Ford 8.8—a collaboration by GearFX Driveline and Detroit Speed that places a quieter, more efficient Ford 8.8-inch ring and pinion gearset into a removable, dropout third member designed to bolt directly into any standard Ford 9-inch housing. It’s a game changer for no more ‘nine whine.’

From Mick’s Paint, the GTO went to Gabe’s Custom Interiors, San Bernadino, CA where they employed high end materials such as Lamborghini leather and the same carpeting used by Rolls Royce. The big change, however, was swapping out the factory woodgrain for a forged carbon material from Composite Speed Technologies, Simi Valley, CA. The custom badges were made by Billet Badges, Ramona, CA.

As sleepers go, Nick Walker’s 462-powered GTO has got to be one of the coolest in town because it’s subtle, and understated, and loud all in the same package. A bit like a Kicker audio system that goes to 11.
