1977 Chevrolet Corvette LS3 Conversion at the V8 Speed and Resto Shop

This deep blue 1977 Chevrolet Corvette came to the V8 Speed and Resto Shop for a new driveline including an LS3 V8, a Tremec TKX 5-Speed manual transmission, and more. These Corvettes look cool and handle well, but the often anaemic, low-compression “smog motors” from the mid 1970s leave much to be desired in the performance department. The V8 Speed and Resto Shop installed a Chevrolet Performance LS3 430 HP crate engine and the Tremec TKX 5-Speed transmission from Modern Driveline designed for high RPM shifting. Dakota Digital RTX gauges provide the driver with the vitals without looking like an add-on. Other suspension upgrades, new wheels, tires, and brakes, sidepipes, and a complete interior restoration by V8 Speed and Resto all add up to a great looking and performing Corvette. If you didn’t think you were a fan of mid 1970’s Corvettes… you are now!

Adding some “Bad” to the Bandit!

Calling all Trans Am fans! Buckle up, because V8 Speed and Resto Shop is taking a classic 1977 Firebird and turning it into a pro-touring monster. This isn’t your average T-Top Trans Am – it’s a non-T-Top model that’s about to receive a complete overhaul.

530 Horsepower Heart Transplant

The centerpiece of this transformation is a brand new LS3 V8 engine. This beast pumps out a whopping 530 horsepower, a far cry from the original engine’s output. To handle all that extra power, the shop is also installing a 4L70E overdrive transmission.

Straightening The Curves

But it’s not just about straight-line speed. V8 Speed and Resto knows that a pro-touring car needs to handle corners like a dream. That’s why they’re outfitting this Trans Am with a Global West suspension system. This upgrade will ensure precise handling and confidence-inspiring grip. YearOne 17″ wheels complete the look for any Trans Am!

Comfort is also important, even for a car built for performance. The shop isn’t forgetting about everyday usability. They’re installing a Vintage Air A/C system to keep things cool on those hot summer days.

To keep the driver informed, the classic instrument cluster is being replaced with a modern Dakota Digital gauge setup. This will provide all the essential information in a clear and stylish way.

1968 Oldsmobile 442 Pro Touring built by V8 Speed and Resto Shop

Adding Modern Performance And Handling To A Classic Envelope

This cool yellow 1968 Oldsmobile 442 looks great, but the owner wanted better handling, braking, and comfort, while adding more reliable power and a smoother shifting transmission to the car without sacrificing the classic look. The solution is the installation of at Roadster Shop chassis and an LS3 V8, hooked to a Tremec TKX 5-speed manual transmission.

Restoring As Needed

This 1968 Oldsmobile 442 had been restored once, but we discovered some areas needing attention. We replaced the rusty dashboard and performed some floor pan repairs during the process. The goal was to perform the required tasks without re-restoring the entire car.

Upgrades With Drivability In Mind

The foundation is a Roadster Shop chassis, which is not only stiffer than the original GM chassis, but it also incorporates improved suspension geometry, stroger parts, and spring, shock, and steering technology over 50 years more advanced than the 1968 design. The end result is a car that drives phenomenally well while not losing the original 442 appearance.

LS3 + TKO = Way More Fun!

The nearly 500 HP all-aluminum LS3 V8 engine provides modern and reliable power while saving weight and eliminating old-design leaks. A Tremec TKx 5-speed transmission is able to handle over 600 ft-lbs of torque and adds an overdrive 5th gear, all while capable of 7500+ RPM shifts. It is geared to match the rear axle ratio and power curve of the engine, so the hydraulically-clutched 5-speed adds to the fun while being easy to drive.
