Thinking about a 7.3L Godzilla swap in a 1999–2004 Mustang? At the shop, the details beyond the engine matter: clearance, controls, driveline, cooling and exhaust. Use our five-system planning guide before buying parts: https://smgspeed.com/blogs/news/godzilla-v8-mustang-swap-five-systems-to-plan

A lighter wheel or brake component only helps when it suits the car and the way you use it. For a street or track build, check wheel clearance, tire choice and brake thermal capacity together.

A throttle-body upgrade is a whole-build decision. Intake plumbing, blade control, manifold match and calibration all affect the result—“bigger” alone is not a diagnosis.

Raptor R tuning is a whole-truck job. COBB’s new 2023–2026 support pairs engine and transmission maps and includes a tire-size adjustment feature. Fuel choice, hardware, logs, drivability and emissions paperwork still need checking for the exact truck.

For performance-shop tuning, a clean log and a repeatable test plan matter more than a single headline number. HP Tuners' new VCM Telemetry workflow can capture drives with compatible MPVI4/RTD4 interfaces without keeping a laptop in the car, then make completed logs available for remote review when connected.

BUILT FOR BOOST. 🔥

Fresh machine work is back and the NTHP engine room is getting busy.

On deck:
• Two L8T 6.6L blocks
• An iron 6.0L
• A bored 5.3L
• And yep… notice that LSX block hiding in the mix? 👀

Fresh coat of paint now. Assembly next. Boost after that.

Which one would you build?

Built for Boost by North Texas High Performance.

A performance build should work as a complete system. Holley's MoParty 2026 profiles highlight cars designed for autocross, towing and long-distance driving—not one universal power recipe.

Our new guide covers the shop-side planning: cooling, fuel, brakes, tires, driveline, packaging and calibration. Read it: https://smgspeed.com/blogs/news/moparty-2026-build-lessons-plan-the-whole-car

Looking this hot. Keeping its cool. 🍊❄️

Don’s super fine ’69 Camaro just wrapped up its latest round of upgrades here at NTHP, and this Tangelo Orange beauty is ready to head home!

A new DeWitts LS swap cooling system helps keep the LS3 cool while Don shows it off, and an A/C refresh has ice-cold air back on duty for those hot Texas days. Cool under the hood. Cool behind the wheel.

With an LS3 crate motor, six-speed manual, Baer brakes, and that gorgeous Tangelo Orange paint, this restomod has plenty to show off—and now even more reason to get out and enjoy it.

Thanks for trusting us with your Camaro, Don. Till we see you again, my friend! 🧡

Ford’s Mustang Dark Horse SC puts a supercharged 5.2L V8, dual-clutch transmission, MagneRide suspension and carbon-ceramic brakes into one integrated street-and-track package. For builders, the lesson is simple: plan cooling, fuel, driveline, braking and calibration together before adding power.
