Fast-forward to this century when Sidney and his son, Sam, found Tom Argue of Tom Argue Design in Clearwater, Florida. Argue and his crew have been specializing in restorations and custom builds for over 20 years.

When the father and son team initially contacted Argue, they discussed their goal of a Pro Touring car with modern suspension, high performance, comfort, and, of course, reliability. The three reviewed multiple options, beginning with replacing the Chevelle’s tired V-8. Although several Chevrolet Performance naturally aspirated crate packages were available, they topped out at about 525 hp, not quite in line with the Dyson team’s go-faster philosophy. Argue suggested a BluePrint Engines 427ci, LS3-based stroker package capable of a stout 635 hp.

Handling concerns were next on the list, especially knowing that cars built in the mid ’60s saw enough lean-in turns to jeopardize the door handles. Argue recommended an ExtReme Chassis from Speedtech Performance. The frame’s built-in, high-clearance geometry and enhanced upper and lower front control arms would allow both a low profile and a tight turning radius. Forged aluminum spindles with heavy-duty C7 hubs teamed up with their torque arm rear suspension, holding a Speedtech Performance 9-inch housing with Dutchman-built, Eaton limited-slip rear, and 31-spline axles. With most of the items on the menu finalized, the ordinary was about to become extraordinary.

When the car arrived at the shop it was determined there was evidence of several previous paintjobs. Rudimentary repairs had been made over the years, complete with artistic applications of chicken wire and Bondo. Mediablasting showed that the car needed both rear quarters, a trunk pan, decklid, floor, and more, causing a rebuild process that required a full year just to return the body back to stock.

While the bodywork was underway, Tom concentrated on chassis upgrades, turning to Sweet Manufacturing for their fast rack-and-pinion power steering, then bolting up Viking Warrior double-adjustable coilovers to ensure autocross-level handling. Finally, Baer 14-inch, six-piston calipers on all four corners provide that critical dose of friction necessary to rein in 600-plus horsepower. The chassis became a roller thanks to Forgeline RS6 Center Lock rims, featuring true knock-off hubs with 19x10s up front and 19x12s in the rear. Michelin Pilot rubber sticks the car’s thundering herd of horses to the asphalt.

The engine compartment received a complete makeover with a clean firewall and new inner fender panels designed to accent the showy new powerplant. Although the 427 came equipped, Argue turned to CVF Racing for their pulley system to power the Vintage Air A/C and power steering. Ultimate stainless steel headers, a custom Argue-designed exhaust, and MagnaFlow mufflers ensured free breathing while simultaneously announcing arrival to the neighbors. Both Dysons are fans of the three-pedal shuffle, so the T56 Magnum six-speed transmission was the right choice. Bowler Stage 2 internal upgrades and a Tilton twin-disc clutch allows for higher rpm shift points under heavy torque loads.

Once handling and performance needs were met, the goal was to reinvigorate the car’s original identity rather than tamper with an already-successful design. The front fenders were widened to accommodate the front wheel and tire package. The cowl panel was smoothed, the driprails eliminated, and several seams welded shut—all designed to keep the car fairly stock looking. LED headlights reside up front, and all the chrome and stainless was either polished or replaced. Called “Blue Dream,” the custom-mixed PPG paint is a close shade to the original.

The interior features stock-looking but subtly customized Hyundai bucket seats. A new center console was fashioned to accommodate the distinctive Bowler shifter. Argue used Hydes Leather on everything except for the factory headliner. A stereo adds to the fun on a road trip, beginning with a Custom Autosound radio that controls a pair of 6×9 speakers set in the rear package tray. Argue squeezed twin tweeters into the factory center location on the dash and stuffed a Pioneer amplifier/sub combination under the driver seat. The Dakota Digital RTX gauges keep track of vital information with an unexpected twist. Sidney found out that the car was capable of a bit more performance than expected, especially after learning about the RTX speedometer’s High Speed Recall (tattletale!) feature that recorded one of Sam’s triple-digit adventures. Gotcha! Nu-Relics power windows, Bowler Touch and Go push-button start, and keyless entry system added new millennium upgrades to the ride.

How is the completed car to drive? The chassis possesses just the right choice of ride height—somewhere between stock and slammed. Both Dysons get behind the wheel on a regular basis and the current altitude has proven to be the perfect blend of a sleek, low profile without the anguish of an errant speed bump. The Viking double-adjustable coilovers are set for a softer, more pleasant ride although with just a few quick turns, the car can slide sideways through the cones at an autocross. Finally, the 625hp V-8 is quick enough to outrun a thunderstorm, tempting both men to ignore their limitations.

Thanks to the right dose of talent and dedication, this louder, faster, better, half-century favorite might just be around for another 50 years!
