TSP 2004-2006 Pontiac GTO LS1/LS2 Camshaft Package

A vehicle-specific Texas Speed camshaft package for 2004-2006 Pontiac GTO models equipped with the cathedral-port LS1 or LS2. Choose the camshaft profile and either the PAC beehive or higher-capacity TSP/PAC dual spring package.

Choose Your Camshaft

• Stage 1 N/A: Mild street profile with broad power gains and the strongest drivability.
• Stage 2 N/A: More aggressive street profile with increased midrange and upper-rpm performance.
• Stage 3 N/A: Aggressive naturally aspirated street and strip profile.
• Stage 4 N/A: Maximum-effort naturally aspirated profile requiring supporting modifications.
• Bald Eagle N/A: Performance-oriented naturally aspirated profile with a pronounced idle.
• Bald Eagle Boost: Boosted cathedral-port profile for properly supported combinations.
• Dumpster Fire Turbo: Turbo-focused cathedral-port camshaft for stock-stroke boosted combinations.

Choose Your Spring Package

• PAC Beehive: PAC 1219 single beehive springs, valve seals and hardened chromoly pushrods.
• TSP/PAC Dual Spring: Higher-capacity dual springs with titanium retainers, integrated seats/seals and hardened chromoly pushrods.

Engine and timing note: The 2004 GTO uses the LS1 while 2005-2006 models use the LS2. Verify the selected camshaft bolt pattern, cam sensor arrangement and upper timing gear for the exact engine and model year.

Transmission note: Automatic cars may require a matched converter depending on cam selection. Manual cars require consideration of clutch condition and low-speed drivability.

Pushrod and clearance note: Final pushrod length and piston-to-valve clearance must be measured during assembly.

Tuning required: Professional custom calibration is mandatory. No tune, tuning device, credits or remote tuning support is included.

Fitment: 2004 Pontiac GTO with the 5.7L LS1 and 2005-2006 Pontiac GTO with the 6.0L LS2. Not for unrelated Pontiac V8 or V6 applications.

Local installation: North Texas High Performance can provide separately quoted installation, converter recommendations and tuning for local customers.
