The Texas Speed LS3 Brawler Heads and Cam Kit packages a pair of Brawler LS3-style CNC-ported rectangular-port cylinder heads with the buyer's choice of Texas Speed LS3 camshaft and a set of Texas Speed 5/16" .080" wall hardened chromoly pushrods. It is built for LS3-based street, track, naturally aspirated and power-adder combinations, with the camshaft chosen to match the goals of the build and the vehicle it goes in.
The Brawler heads ship with the Texas Speed .660" spring kit and titanium retainers installed. Seventeen Texas Speed rectangular-port camshafts are offered, from the L92 truck stages and the Stage 1 through Stage 4 F-35 naturally aspirated grinds to the Chop Monster, Honey Badger, Bald Eagle, turbo, centrifugal and positive displacement supercharger cams. Texas Speed publishes no fixed horsepower rating for the package because output, idle quality and drivability depend on the camshaft, compression, supporting parts and tuning. An LS3 head and cam gasket kit is required, new head bolts or studs are recommended, and professional tuning is required after installation.

Optional add-ons offered by Texas Speed for this kit include an HP Tuners MPVI4, a Texas Speed 3-bolt conversion kit or Rollmaster LS3 single roller timing set, a camshaft retainer plate and bolt kit, a GM or ARP balancer bolt, a GM high performance or Melling oil pump, a pushrod length checker and a rocker arm trunnion upgrade kit (Texas Speed, CHE, Comp Cams or Manton).
Note: An LS3 head and camshaft gasket kit is required and new head bolts or head studs are recommended. Valve springs must be matched to the selected camshaft. AFM/DOD or VVT-equipped applications may require additional delete components, torque converter and rear gear requirements vary with camshaft selection, and fuel system upgrades may be required for higher-horsepower combinations. Verify camshaft, valve spring, pushrod, AFM/DOD, VVT and supporting component requirements for the specific combination before installation.
