BTR 5.3L Truck Norris 460 HP Power Packages
BTR 5.3L Truck Norris 460 HP power packages are engine upgrade kits designed to boost a stock GM 5.3L LS truck engine to roughly 460 hp while maintaining reliable daily street manners. These packages from Brian Tooley Racing are built for enthusiasts who want their 5.3L to sound mean, make more power, and still have the street manners to drive anywhere.
Key features and performance:
* Power output: Produces around 458.6 hp at 6,450 rpm and 398.5 lbs.-ft. of torque at 4,550 rpm (when paired with a TrailBlazer SS style intake)
* Driving character: Built for daily-driven trucks, street builds, and weekend cruisers needing strong low- and mid-range usability alongside top-end gains
* Sound: Features the aggressive, distinct idle sound characteristic of the popular Truck Norris camshaft profile
* What's included: The combination centers around BTR's signature Truck Norris camshaft, matched valvetrain components, an intake manifold setup (such as the TRINity or compatible GM truck intake options), and supporting fuel/hardware accessories designed to work together synchronously
