1970 Pontiac GTO Hardtop Coupe

This 1970 Pontiac GTO is a custom-built American muscle car finished in black with a matching vinyl roof and a refreshed interior. Powered by a high-performance 461ci Pontiac stroker V8 paired with a 4L80E four-speed automatic transmission, the car underwent an extensive mechanical and interior refurbishment between 2023 and 2025.

The exterior features a body-color Endura front bumper, twin-scoop hood, rear spoiler, quad headlights, tinted windows, and quad exhaust outlets. The car rides on 17-inch Rally II-style wheels with Mickey Thompson tires and features upgraded Hotchkis, QA1, BMR, and Viking suspension components, along with Wilwood six-piston front disc brakes.

The refurbished interior includes upgraded seating, a Formula-style steering wheel, air conditioning, engine-turned dashboard trim, woodgrain accents, and an Alpine Bluetooth stereo with JBL speakers. Modern instrumentation includes a Holley Terminator X digital display and a shift light.

The Tytech Performance-built 461ci stroker V8 was installed in 2024 and features Holley Terminator X electronic fuel injection, a Kauffman intake manifold, aluminum cylinder heads, a custom camshaft, and an upgraded cooling system. A dynamometer report indicates an output of 652 horsepower and 632 lb-ft of torque.

Power is delivered to the rear wheels through a 4L80E automatic transmission with a lockup torque converter and a 12-bolt rear axle featuring a Detroit Truetrac limited-slip differential with 3.90:1 gearing. Additional performance upgrades include Hooker long-tube headers and a custom exhaust system with Flowmaster mufflers.

The vehicle is accompanied by a build sheet and documentation of its extensive modifications.
