The Texas Speed Stage 2 LS3 N/A Camshaft is a 229/244 mid-duration grind for LS3 and LS2 engines with L92/LS3 rectangular-port heads. It is the step up for buyers who want more than the Stage 1 225/236 while keeping good street manners, with its power gains concentrated from 3,000 rpm up and a noticeably stronger chop at idle.
Texas Speed reports gains of 84 horsepower and 27 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 torque converter with at least a 2,600 rpm stall speed, and no rear gear change is required. The operating range is 2,000 to 6,800 rpm. Texas Speed says it fits stock untouched heads with no piston-to-valve clearance issues, though measuring is recommended. The cam is 3-bolt only and a custom tune is required.

FAQ
What engines does the Texas Speed Stage 2 LS3 N/A cam fit?
Texas Speed recommends it for LS3 and LS2 engines using L92/LS3 rectangular-port cylinder heads, meaning 6.0L and 6.2L engines such as the LS3, L99, L92 and L76 found in 2007 and later GM cars, trucks and SUVs.
Do I need a stall converter with the Stage 2 LS3 cam?
Yes, in an automatic. Texas Speed requires a torque converter with a minimum 2,600 rpm stall speed. No rear gear change is required for this camshaft.
How much power does the Stage 2 LS3 camshaft make?
Texas Speed reports gains of 84 horsepower and 27 lb-ft of torque over the stock camshaft, with the strongest improvement from 3,000 rpm and up. Actual results depend on the rest of the combination.
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.
Will the Stage 2 LS3 cam clear stock pistons and heads?
Texas Speed states the cam fits stock untouched heads with no piston-to-valve clearance issues, but recommends measuring clearance during any camshaft installation.
How does the Stage 2 compare to the Stage 1 and Stage 3 LS3 cams?
The Stage 1 (225/236) keeps the factory converter. The Stage 2 (229/244, 112 LSA) adds midrange and needs a 2,600 rpm stall. The Stage 3 (231/246, 111 LSA, .640" lift) adds more top end and needs a 3,200 rpm stall.
