How to Run Out of Gas in the Desert on I-15 in a Muscle Car

A stroked LS3 and a ten-mile traffic jam near the California-Nevada line were all it took to strand Project Orange Krate, the Chevy High Performance 1971 Camaro, on the shoulder of Interstate 15 after the 2017 Holley LS Fest West. With Vette and Street Rodder editor Brian Brennan in the passenger seat and no working fuel gauge, it became a lesson every pro-touring builder eventually learns: horsepower changes your fuel math more than you think.

The stroked LS3 was singing along at 70 mph, the desert was sliding past the half-open windows, and then the engine coughed once and went silent. That is how Project Orange Krate, the Chevy High Performance 1971 Camaro, came to a stop on the shoulder of Interstate 15 somewhere in the California desert on the way home from the 2017 Holley LS Fest West. In the passenger seat was Brian Brennan, editor of Vette and Street Rodder, and he had opinions about a driver who set out across the Mojave with no working fuel gauge. The traffic jam that scrambled the fuel math was real. So was the silence. What happens when one of the longest-running project cars in magazine history runs dry in the middle of nowhere?

A Project Car With a Pedigree

Orange Krate is not just any second-generation Camaro. Its lineage traces back to Camaro Performers magazine, and in the world of long-running magazine project builds it trails only Project X, the famous 1957 Chevy that debuted in the August 1965 issue of Popular Hot Rodding and remains arguably the most famous project car ever built. That history is why a stalled Camaro on I-15 was more than an inconvenience. It was a piece of magazine build culture sitting on a shoulder with trucks blowing past at highway speed.

The Engine That Changed the Math

Under the hood is a stroked LS3, which means a modern 6.2-liter small-block that has been given extra displacement for more torque and more power. That is a wonderful thing on a road course or a dragstrip and a slightly dangerous thing on a long desert highway, because the fuel economy assumptions a driver carries around in his head were formed by a very different engine. More power means more fuel, especially when the driver is enjoying the aggressive exhaust note, and a car that feels like it can run forever is exactly the car that surprises you.

No Gauge, No Warning

The Camaro’s fuel gauge was not functioning, which turned every tank into an exercise in mental arithmetic. Plenty of project cars run this way for a while, since a gauge is easy to put off when there are more exciting things to finish. It works fine until the arithmetic goes wrong. On a known route with predictable speeds, a driver can get away with counting miles. On a route that suddenly includes a long stop-and-go crawl, the assumptions break, and the first warning is the engine stopping.

The Traffic Jam That Did It

The specific culprit was a ten-mile traffic jam that hit about fifteen miles outside the Nevada-California line. That stretch of I-15 is notorious for weekend backups as Las Vegas traffic funnels back toward Southern California, and sitting in it for an hour with the engine idling and the air conditioning working burned fuel that had been budgeted for cruising at 70. By the time the road opened up again, the tank was much emptier than the miles-driven calculation suggested, and there was no gauge to say so.

Why the Desert Makes It Worse

Running out of fuel in town is embarrassing. Running out on the I-15 corridor through the Mojave is a different category of problem. Exits are far apart, services are sparse, summer temperatures are brutal, and cell coverage can be spotty. A car with a hot big-power engine and a driver in a T-shirt is not equipped for a long walk. The desert does not care how famous the project car is, which is exactly why the shoulder of that highway is the wrong place to learn a lesson about fuel reserves.

Brennan’s Perspective From the Passenger Seat

Brian Brennan has spent a career around hot rods and Corvettes as an editor, and his reaction was less about the inconvenience than about the avoidable nature of it. A working gauge and a conservative fill-up strategy would have prevented the whole episode. His point stands for any builder: the boring systems on a project car, the gauge, the sending unit, the wiring, are the ones that keep the exciting systems from stranding you. Nobody writes a feature about a fuel gauge, but everybody remembers the day it was not there.

LS Fest West and the Trip Home

The weekend itself had been a good one. The 2017 Holley LS Fest West in Las Vegas is a celebration of everything LS-powered, from drag racing to autocross to show cars, and Orange Krate was right at home there. The trip back is where the story turned. That contrast is familiar to anyone who has driven a project car to a distant event: the car performs perfectly under the spotlights and then reminds you on the drive home that it is still a project.

The Fuel Math Every Builder Should Do

The practical lesson is simple to state and easy to ignore. A car with significantly more power than stock will use significantly more fuel, and the difference gets bigger in traffic, in heat, and at speed. Builders should budget more reserve than the gauge, or the mental gauge, suggests, and on long remote stretches like I-15 they should fill up earlier than feels necessary. A fuel stop that turns out to be unnecessary costs ten minutes. A missed one costs an afternoon and a story you will hear about for years.

What Pro-Touring Cars Ask of Their Owners

Orange Krate is a pro-touring build, which means it was designed to be driven long distances at modern highway speeds with modern power and handling. That capability creates its own kind of overconfidence. The car feels so composed at 70 that a driver stops thinking of it as a forty-year-old Camaro with a hand-built fuel system and starts treating it like a new car. It is not a new car. The pro-touring formula makes old cars usable, but it does not make them idiot-proof, and it does not fix a gauge that was never hooked up.

A Better Ending Than It Could Have Been

Stories like this one tend to end one of two ways: a long hot walk, or a stranger with a gas can. Either way, the car made it home, and the episode became the kind of tale that gets retold at every LS Fest afterward. That is the real value of a project car with history. Its mistakes become part of the record alongside its successes. Orange Krate now has one more chapter, and any owner planning a desert run in a big-power classic has one more reason to fix the fuel gauge before the next event.
