The Texas Speed Blower Stealth Camshaft is a supercharger-oriented grind for stock 4.8L and 5.3L LS engines with cathedral-port cylinder heads. It uses a wide 115 degree lobe separation angle and minimal overlap, which suits positive-displacement blower and centrifugal supercharger setups where excessive overlap would bleed off boost. The result is more torque and sharper throttle response with an idle and low-speed behavior close to stock, which is why Texas Speed rates it as daily-driver friendly with a mild chop.
The cam is intended to work with a factory stall converter, so it fits budget boosted truck and car builds that keep most of the factory drivetrain. Texas Speed requires a PRC or TSP dual valve spring kit to handle the .600" lift and 5/16" pushrods. A custom tune is required after installing any aftermarket camshaft.

FAQ
What engines does the Texas Speed Blower Stealth Camshaft fit?
The Blower Stealth cam is designed for stock 4.8L and 5.3L LS engines with cathedral-port cylinder heads, such as the Gen III and Gen IV truck and SUV engines found in GM pickups, Tahoe, Suburban and Yukon models.
Is the Blower Stealth cam only for supercharged engines?
It is designed around supercharged and blower setups. The minimal overlap and 115 degree lobe separation keep boost in the cylinder, so Texas Speed markets it as a boosted grind rather than a naturally aspirated cam.
Do I need a new torque converter with this camshaft?
No. Texas Speed designed the Blower Stealth to work with the factory stall converter, which keeps it practical for daily-driven trucks and cars that stay on the stock transmission setup.
What valve springs and pushrods are required?
Texas Speed requires a PRC or TSP dual valve spring kit for the .600" lift along with 5/16" pushrods. Factory springs are not adequate for this camshaft.
How does the Blower Stealth cam idle?
Texas Speed rates the chop level as mild and the vehicle usage as daily-driver friendly. The wide lobe separation gives a near-stock idle compared with the aggressive 108 to 112 LSA grinds in the Texas Speed lineup.
Is a tune required after installing the Blower Stealth camshaft?
Yes. A custom tune is required after any camshaft swap so the engine idles and runs correctly with the new profile and the boosted combination.
