The Goodguys Rod & Custom Association is a force to be reckoned with.

With their first event dating back to 1983 in Pleasanton, California – a small suburb an hour outside of San Francisco – founder Gary Meadors created a cult-like subculture within the world of American hot rodding. Goodguys’ National Summer Series events take place at fairgrounds and speedways from one coast of the country to the other, consisting of car shows, drag races, and a new crowd favorite – autocross.

Traditionally, autocross has seemed to be overlooked by the world of American motorsports. There are some exceptions, of course, but in era most classic American muscle cars weren’t engineered to take a turn at speed. It’s quite unfortunate actually, because when I really think about it, it would’ve been epic to see something like a ‘57 Nomad or a ‘64 Impala gutted and caged with some insane tub work and squared wheels pulling in sub-1:50 lap times at Laguna Seca.

Regardless of that matter though, modern-age tooling and engineering can make pretty much anything handle well enough to dominate the course nowadays. Which is primarily the reason why David Carroll took the high road and built a 1973 Chevy Vega to compete in the Goodguys AutoCross series.
LS All The Things


Before we dig deeper into the Vega, let’s talk about David’s Z. His initial goals were to step outside of the traditional cookie-cutter S30 builds we usually see, and that’s obviously clear at first glance. It screams angry noises at a standstill, and if I saw it coming at me in my rear-view mirror, I’d probably move out of its way. The flares are wide, the wheels are massive, the wing is huge, the brakes are monstrous, and it’s LS powered – everything about this car is extraordinary.

The ‘570Z’ was purpose-built to portray American hot rod style touches on a Japanese icon, and it’s set up for going fast. David often posts videos of him demolishing times at local autocross events on his Facebook timeline, and it’s truly a glorious sight to see.


His problem was that the Goodguys AutoCross event wouldn’t allow for a Japanese car to enter into the series. The rules were strict, and members of the class were even stricter, as they refused to accept the Z any time David attempted to enter it. They are an American hot rod enterprise, after all.

Despite knowing this, David still progressed with building the car to its completion, and as mentioned prior, he still manages to race it on other cone courses throughout the year. And after taking some time to ponder over what he could build next, he decided on the perfect match – a neglected American pony car with half the cylinders conventionally found in muscle cars of the era.
Failure Of The Vega


When the Chevy Vega was first introduced in 1970 it received a tremendous amount of praise from the consumers. It was compact, economical, good looking, and even performed well due to its lightweight design and aluminum engine block. But the praise was short lived, most notably due to serious engineering flaws of the SOHC inline-four power plant. They became notorious for oil consumption and engine cooling issues. Chevy tried to revive the Vega, re-engineering all of the common failure points in the motor, but failed to deliver, which ultimately led to tarnishing the reputation of General Motors as a whole.


Because of this, enthusiasts of the hot rodding world almost always veered away from the Vega, as there simply was no support for the car. With a bad reputation comes diminishing sales, and with diminishing sales comes minuscule efforts in aftermarket support for replacement parts, let alone anything performance related. For instance, if you decided to build a ’57 Bel Air, you could open up a Summit Racing catalog and create an entire car from it, with infinite choices in direction of its theme. But try that today for a Vega and you’ll be stumped at being able to find something as simple as a specific weather seal.


While that may be an automatic sign for most builders to just choose an alternative platform, David found the challenge to be encouraging. He mentioned he specifically wanted the platform to test his own skills at craftsmanship and engineering, while also being in love with the overall appearance and design of the Vega. It reminded him of his 570Z, and thus his custom build began.
The All-Custom Vega


David purchased the Vega sight unseen, and had it shipped to his home in Morgan Hill, California. Immediately after it arrived in his driveway, he began researching and drafting up plans to build it up to proper cone-carving spec. Thoughts of potentially going tube chassis on the car crossed his mind at some point as well, but the decision to keep the chassis original prevailed, and I for one am happy it stayed this way.

I believe in retaining a factory chassis for a car of this caliber, not only because it pushes a builder’s creativity, but also because it enhances a driver’s skill level when pushing the car to its limits. There’s a point in building race cars where I kind of see going tube chassis as cheating when comparing to other cars of its class. I’m not saying it would’ve actually been cheating, but being able to spank the hell out of the competition with an original frame holds more bragging rights in my book.

David spent several months sourcing custom parts for the car. The hardest part was suspension, and though he managed to find the control arms he needed, the rest of the components were custom built. From there, he sourced a crate engine from Chevrolet Performance, but of course it wasn’t a direct fit either. They ended up cutting and moving back the firewall as well as the transmission tunnel to get weight centered in the car. The drivetrain, wheels, brakes, exhaust, fuelling, and so forth were again all custom made and tailored specifically to work with the Vega.

It’s safe to say, they went to great lengths to get the car where it’s at today.
What’s To Come


Now that the Vega is complete and ready for the autocross course, David’s plans are to dominate the series. He’s already been fortunate enough to get the car on the track to get some testing done, and even managed to take home third place in its class without being fully dialed in. With 2019 creeping up faster than ever, David aims to have everything perfected by the racing season, and hopefully taking home some first place trophies.

But that’s not all of course.

Being the hot rodding man he is, David has recently picked up a 1963 Chevy Nova II wagon that he will be building alongside this car and the 570Z during the next year. He’s already started restoring the bodywork, and it’ll be packing some serious heat under the hood as well with Chevy Performance’s new ‘Connect and Cruise’ LT1 package.

Once it’s complete, I’ll be following up with him to showcase his wife’s new grocery and family hauler on the site, so stay tuned for that.
