Jeff Monchilov’s Custom-Built ’73 Speedvette Convertible
Jeff originally purchased this as a project in the summer of 1989, then sold it a few months later. Keeping track of it over the years or decades, he bought it back on his 50th birthday, 11-25-2018. The guy he sold it to in 1989, together with his son, tore it apart yet never finished it. Shortly after Jeff bought it back, it was game on…
These photos are what the 73 Corvette looked like when Jeff bought it back.
Transforming the Exterior
Jeff Monchilov ordered a new custom chassis, including C7 brakes, all the way around. He made a custom Speedvette LT1-style long hood, a C6-inspired decklid with waterfall, and a smooth firewall kit. He also installed 2” rear flares from Custom Image Corvettes. While doing bodywork, he shaved the side marker lights, door locks, and rear deck lid vents to give it that sleek look. Notice the lack of hood and convertible top latches. Jeff makes custom turnbuckles with ball studs to discreetly hold down the top and a linear actuator to power the hood. A single Quik-Latch holds down the decklid.
The rear valance was molded to a super smooth body, and a wiper cover was smoothed and cut down for a transitionless fit. Once the bodywork was complete, Jeff sprayed it with Torch Red base coat clear coat paint. After paint came reassembly, including custom fit new chrome rear bumpers, Schott Turbine 19×9 & 20×12 polished wheels with three bar knockoffs wrapped in Diamond Back Classic 275/35/19 & 335/30/20 Redlines.
Power and Performance
Power is delivered through a new GM Performance LS3 525hp engine backed by a new 4L70e Automatic Transmission. Exterior tunes are via HIGHFLO Performance SweetThunder Chambered side pipes with factory-style chrome covers. A BeCool radiator keeps the motor cool, and a Holley accessory kit spins the pumps. Also added was a Turn One power steering pump pulley. The night lights are from Dapper Lighting and go up and down quickly thanks to Detroit Speed’s electric motors.
The interior is simply incredible. After Jeff cut down the C5 Corvette seats so they wouldn’t extend beyond the decklid, he made custom bezels to house the Dakota Digital HDX gauges; he also designed custom polished billet cup holders and shift bezel which he had Eagle Machining widdle out. He then took the car to Steve Holcomb from Pro Auto Custom Interior and let the crew have free reign. The interior looks like an exotic sports car, yet it’s in a high-end Speedvette creation! The cabin is cooled with a Restomod Air unit with custom controls and vents. The interior tunes are from Pioneer. A Flaming River tilt makes the wheel go up and down. Lokar helps with shifting and pedaling. LED door panel lights were added for a cool interior light show, and a custom glove box was added for storage.
While this ’73 Speedvette is 50 years old… It’s Sexier and Smoother than it’s ever been…
