A New Kind of Cool
For most, street rodding is a celebration of creativity expressed in what they build and drive. Some enjoy it for the visceral pleasure that comes from screaming horsepower and boiling rubber, while others benefit more from the family environment this hobby provides.
Product Spotlight: Pyramid Optimized Design Sequential Aurora Taillight for 1964½–1966 Mustang
If you’ve ever followed a classic Mustang at night, you know the taillights were never its strong suit. Pyramid Optimized Design decided to fix that—with style. The Sequential Aurora Taillight is a modern LED retrofit that finally gives your early Mustang the bright, even illumination it always deserved—no hot spots, no dim corners, no burned-out bulbs.
River Rod Royalty
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.

If you live for pulling trucks, racing, or high-performance applications, this build kit has everything you need to bring your vision to life. It’s designed to fit the standard bore space of big block Chevy heads, making it versatile enough for a variety of builds.
Unparalleled Precision and Quality
What sets this header build kit apart from the rest? It’s all about the details:
- Flanges: The kit includes two American-made, precision laser-cut 3/8″ thick header flanges specifically designed for Big Block Chevy heads. You can also opt for eight single port flanges for easier fabrication and installation.
- Full Bank Port Size Options: Choose from 2″, 2 1/8″, 2 1/4″, 2 3/8″, or 2 1/2″. Single port flange options are available in 2 1/4″, 2 3/8″, or 2 1/2″.
- Mandrel Bends: You get twelve 180-degree J bends with 6″ and 12″ legs. These extra-long legs mean you won’t need to buy additional straight tubing. The bends are crafted from American-made 304 stainless steel, which forms better, welds better, and lasts longer.
- 4 into 1 Collectors: The kit offers precision-formed 4 into 1 collectors or optional super high-flow slip-on merge collectors with four sets of collector tabs. Like the bends, these collectors are made from top-quality American-made 304 stainless steel.
- Collector Stars: These laser-cut stars simplify the fabrication process, acting as a weld-in block between the tubes before attaching the collector.
- Purge Caps: Back purging is a breeze with these caps. Each kit includes four primary caps and one collector cap.
- O2 Bungs: Two precision-machined, weld-on O2 bungs are included. Made from 304 stainless billet, they weld beautifully.
- Tig Filler Rod: The kit includes a half-pound package of filler rod, ensuring you have everything you need for a perfect weld.
