Inside the 2026 Grand National Roadster Show, the thunder didn’t stop at the hot rods. Tucked among the country’s finest customs and street machines was a killer lineup of vintage ski hydros, circle boats, and heirloom river runners that brought serious waterborne attitude to the show floor. Blown big-blocks, hand-laid gelcoat, and family-built history were on full display, proving that the hot rod mindset runs just as deep on the river as it does on the street.
Let’s cut to the chase, because this definitely isn’t your grandpa’s set of rusty old manifolds. The HDR Sequential 8-1 Headers from Stainless Headers are a next-level, hand-crafted performance weapon for big-inch V-8s — purpose-built for jet boat and high-output marine applications — and they were one of the most talked-about exhaust systems as seen at PRI 2025.
Building an engine that produces more horsepower than its stock configuration can be done in many ways. However, supercharging has proven to be one of the best ways to make the most horsepower over stock. Superchargers are air pumps that force a “super” charge of air into an engine, which in turn allows the engine to make more power. A Roots supercharger or blower is a sealed case with two rotors inside. It is driven through the crankshaft by belts and pulleys, causing the spinning rotors to force compressed air into an engine.
In the world of high-performance builds, attention to detail sets great cars apart from the rest. That’s why Factory Performance™ Parts, a division of PROFORM® Parts, has taken a fresh approach to a time-tested workhorse with the launch of the new Slant-Edge 100 Amp Alternators—a stylish, high-output evolution of the iconic GM 10SI. Designed for those who care as much about what’s under the hood as how it looks when the hood is up, the Slant-Edge delivers form and function in equal measure.
If you thought the Grand National Roadster Show was just about hot rods and customs, think again. Tucked away in Expo Building 8 was a full-blown horsepower fest on water, with a killer lineup of vintage drag boats, Grand National circle racers, and custom-built speed machines that make as much noise as they do waves. If you love anything that rips, this was the place to be.
When it comes to muscle, power, and performance, you can’t beat a big block Chevy. And if you want to harness that raw power, there’s no better way to do it than with a custom set of headers. Enter the Pro Series Big Block Chevy Round Port Custom Header Build Kit from Stainless Headers Mfg. Inc. – the ultimate toolkit for any serious fabricator.
If there’s one thing we can’t stress enough, it’s the importance of keeping your engine cool. That’s why we’re pumped about the Canton Racing Products Universal Aluminum Coolant Expansion Fill Tank. This baby is an absolute game-changer for anyone looking to optimize their vehicle’s cooling system.
Alright, buckle up because Eddie Motorsports just dropped a bombshell in the form of their new line of high quality, billet aluminum steering wheels. Picture this: a line of wheels so slick, so badass, that your ride’s gonna scream “legendary.” Yeah, it’s that good.
Alright, gearheads, if you’ve been chasing that extra performance edge for your LS engine, it’s time to step up your game. The BTR Platinum LS Dual Spring Kit – .660 Lift (SK001) from Brian Tooley Racing is the go-to upgrade when you’re running a high-lift cam and want to keep things dialed in tight. Let me tell you, this kit is more than just parts in a box—it’s the insurance policy your high-performance build demands.
If you’ve ever imagined a time when you could simply pick up the phone or send an e-mail to General Motors and order the engine of your dreams, pull it out of a box delivered to your door and plug it into the car of your dreams, then stop dreaming as that time has come. While it’s not new information that GM Performance Parts provides an assortment of engines to choose from, it’s never been easier to select the one that is best for your budget and the intended purpose of your car.
