The Texas Speed LT Stroker Stage 1 3-Bolt N/A Camshaft is ground for large-displacement Gen V LT stroker engines that have been converted to a traditional three-bolt camshaft drive. It targets aggressive naturally aspirated builds of 400 or more cubic inches and delivers its gains in the midrange and top end while keeping the valvetrain stable at high rpm.
The grind measures 239/259 duration at .050", .646"/.631" lift and a 110 degree lobe separation angle installed 2 degrees advanced, with a 32 percent fuel lobe for the direct injection pump. Texas Speed requires its TSP/PAC .660" valve spring kit and 3/8" pushrods, recommends PAC-1209X springs and Johnson lifters above 7,000 rpm, and says the cam performs best with aftermarket cylinder heads and an aftermarket intake manifold. Aftermarket pistons with valve reliefs are required for piston-to-valve clearance, and a custom tune is required after installation.

FAQ
What engines is the Texas Speed LT Stroker Stage 1 3-bolt cam for?
It is for naturally aspirated Gen V LT-based stroker engines of 400 or more cubic inches that use a 3-bolt camshaft drive and aftermarket pistons with valve reliefs. It is not intended for a stock-displacement LT1, LT4, L83 or L86.
What are the specs of the LT Stroker Stage 1 3-bolt camshaft?
The cam has 239/259 degrees of duration at .050", .646" intake and .631" exhaust lift, a 110 degree lobe separation angle installed 2 degrees advanced and a 32 percent fuel lobe.
What valve springs and pushrods does this cam require?
Texas Speed requires its TSP/PAC .660" valve spring kit and 3/8" pushrods. For engines turning more than 7,000 rpm, Texas Speed recommends PAC-1209X valve springs and Johnson lifters.
How is the 3-bolt Stage 1 different from the standard Texas Speed LT Stroker Stage 1 cam?
The 3-bolt version is for engines converted to a three-bolt cam gear and carries 239/259 duration, while the standard LT Stroker Stage 1 cam is 239/254. Both share .646"/.631" lift, a 110+2 LSA and a 32 percent fuel lobe.
Do I need aftermarket heads and pistons for this camshaft?
Aftermarket pistons with valve reliefs are required for piston-to-valve clearance. Texas Speed says the cam performs best with aftermarket cylinder heads and an aftermarket intake manifold in a free-flowing top end.
Is a tune required after installing this camshaft?
Yes. A custom tune is required after any camshaft swap so the engine runs correctly with the new profile, the 32 percent fuel lobe and the deleted VVT on a 3-bolt conversion.
