The Texas Speed Stage 3 LS3 N/A Camshaft is a 231/246 grind for LS3 and LS2 engines with L92/LS3 rectangular-port heads, aimed at buyers who want a more aggressive cam than the Stage 2 229/244 with a bit more top-end power. The .640" intake lift and 111 degree lobe separation deliver strong gains while Texas Speed still describes it as a street-able cam that can be daily driven once properly tuned.
Texas Speed reports gains of 88 horsepower and 28 lb-ft of torque at a 10.5:1 or higher compression ratio. The TSP/PAC .660" dual valve spring kit is required, automatics need a minimum 3,200 rpm stall converter, and no rear gear change is required. The operating range is 2,000 to 6,900 rpm. The cam is offered only on a 3-bolt core, and a custom tune is required after installation.

FAQ
What engines does the Texas Speed Stage 3 LS3 N/A cam fit?
Texas Speed recommends it for LS3 and LS2 engines using L92/LS3 rectangular-port cylinder heads, which means 6.0L and 6.2L engines such as the LS3, L99, L92 and L76 in 2007 and later GM vehicles.
What stall converter does the Stage 3 LS3 cam need?
Texas Speed recommends a minimum stall speed of 3,200 rpm for this camshaft in automatic vehicles. A rear gear change is not required.
How much power does the Stage 3 LS3 camshaft add?
Texas Speed reports gains of 88 horsepower and 28 lb-ft of torque over the stock camshaft, with more top-end power than the Stage 2 229/244. Results depend on heads, intake, exhaust and tuning.
Will this 3-bolt camshaft fit an engine with a single-bolt factory cam?
Only with a conversion. The cam is sold on a 3-bolt core, so a single-bolt engine needs the three-bolt conversion kit with the 4x upper timing gear plus the ARP three-bolt camshaft bolt kit, both sold separately by Texas Speed.
Can the Stage 3 LS3 cam be daily driven?
Yes. Texas Speed describes the Stage 3 as a great street-able cam that can be daily driven once properly tuned, with a choppy idle and a 2,000 to 6,900 rpm operating range.
What is the difference between the Stage 3 and the Stage 4 F-35 LS3 cam?
The Stage 3 (231/246, .640" lift, 111 LSA) needs a 3,200 rpm stall and stays daily-driver friendly. The Stage 4 F-35 (235/248, .649" lift, 111 LSA) is the most powerful cam for a stock LS3 short block, needs a 3,600 rpm stall and is not recommended as a daily driver.
