This 1964 GTO Road Race Build is All Kinds of Awesome

Now, there’s something you don’t see everyday – a 1964 Pontiac GTO outfitted for road racing, equipped with a carbureted LS3.

Reminiscent of the early days of Trans-Am series racecars, this Pontiac GTO is a modern marvel with a dose of nostalgia. Don Stellhorn is the owner of this masterpiece of a GTO and he wouldn’t have it any other way – this is his vision of what a 1964 GTO road race car should look like. Would we change anything? Probably not.

From start to finish, the build took quite a bit of time – seven painstaking years, to be exact. All of the work on the car was done by Stellhorn himself, and he did a stellar job with the craftsmanship. There are so many cool touches that give the car a modern vibe.

First of all, the LS3 engine under the hood is carbureted and is no slouch, by any means. Stroked to 416 cubic inches, the LS3 is comprised of an SLP/Manley rotating assembly, a 3-stage Aviaid dry sump oil system, CNC-machined L92 Chevrolet Performance heads, Edelbrock Victor Jr. intake manifold, and a custom 1000 CFM Holley carburetor.

The end result is 652 horsepower at 6,700 RPM and 529 pound-feet of torque at 6,100 RPM – what a monster!

Looking through the build pics on Stellhorn’s website, gtoroadracer, we noticed a lot of really cool fab work in different areas of the car. One of the most unique touches to the car is the custom aluminum brake cooling system for the front brakes – two hoses feed air to the rotor, while another hose feeds air to the massive caliper – we thought that was really cool (pun intended.)
