If you caught this article back in 2019, you may be wondering what happened to Project SALT. The answer is that it’s been patiently waiting for its turn to come back to life. Today, at the first High Performance Expo in Charlotte, NC marks the day many of us have been waiting 15 years to witness.
Selecting And Mounting The Right Parachute For Drag Racing

1 month ago | lsxmag.com | Brian Wagner

Parachutes are an important piece of drag racing safety gear. You don’t buy any random parachute, bolt it up to your vehicle, and hope for the best. In this article, we’re going to cover what you need to know when it comes to buying a parachute for your vehicle, and what to expect when you deploy it for the first time. Since Project Red Dragon is dancing on the very edge of the 150 mph requirement for a parachute, it was time to add one before we really turned the car up.
Top Five Hottest Budget LS Swaps

1 month ago | lsxmag.com | Scott Parker

Holley LS Fest Texas 2025 was a hot and humid affair, but I’m not just talking about the weather… We got hot and bothered about several LS-swapped vehicles at Texas Speedway and had to share because – well – that’s our job! Spoiler alert: they were not the highest dollar builds on the property either. But they weren’t junk either – some had turbos, built engines, high-end shocks, etc. Since this was Texas, most of them were – no surprise – trucks.
Making Over 900 HP With A ProCharger P-1X On Our Budget 5.3L

1 month ago | lsxmag.com | Greg Acosta

A while back, we set out to see how cheaply we could make 1,000 horsepower in a reliable package. The goal was 1,000 horsepower for $8,000 (hence the “1K For 8K” name), and while we achieved our power goal, we came up about $1,700 short of the goal. The engine ran great. So great, in fact, we decided to use it as a test mule for another project we had bouncing around in our heads.
Here's Why We Chose An Aftermarket LS Wiring Harness

1 month ago | lsxmag.com | Brian Wagner

Not every engine swap project needs a high-dollar aftermarket EFI system. Sometimes, a simple OEM ECU with basic wiring will get the job done. You could just reuse the OEM wiring harness, but that harness might have its own issues you can’t see with the naked eye. That’s why using a professionally made harness for your project might be the smart move. Let’s face it, OEM parts you grab from the local junkyard or Facebook Marketplace could be compromised.
Moser Engineering Continues It's Made In The USA Traditions

454 Evolution: Turning A 5.3-Liter LS Into A 454-Cube Monster

2 months ago | lsxmag.com | Greg Acosta

Junkyard 5.3-liter engines have always been popular. The iron-block variants are (or were, anyway) cheap and plentiful in junkyards, and you didn’t have to worry about the condition of the cylinders, because there was enough meat to go way more than .060-inch overbore. Gen-III and Gen-IV 5.3-iron blocks were easily punched out to the factory LS1 bore size of 3.898 inches — a whopping 0.118 inch larger than they cam from the factory.

Dale Earnhardt Jr. - The Drag Racer?

2 months ago | lsxmag.com | Andrew Wolf

“That’s f*ckin’ fun!” proclaimed an exhilarated Dale Earnhardt Jr. after the NASCAR icon completed a rip behind the wheel of Cleetus McFarland’s race truck modeled after Dale’s legendary late fathers’ number 3 Goodwrench Chevrolet at the Talladega Superspeedway recently. “I’m ready to go a real strip, I want to run it on a real ‘strip once,” he said. “I’d like to do this a couple more times and ramp it up a little bit.
