The Texas Speed Stage 3 LS7 N/A Camshaft is a performance grind for the naturally aspirated 7.0L LS7 with a lopey idle and hard pull through the mid and upper rpm range. Texas Speed developed custom lobes specifically for the LS7 that make power across the rpm band while staying more stable than most comparable camshafts, which it says translates to a quieter, longer lasting valvetrain.
The cam measures 240/252 duration at .050", .657"/.655" lift with the factory 1.8:1 LS7 rocker ratio and a 111 degree lobe separation angle, with a power band of 2,800 to 6,900 rpm. Like all Texas Speed camshafts it is developed, ground and polished in-house on Landis CNC camshaft grinders, and it was designed on a factory GM 7.0L LS7 with no other internal changes. Upgraded valve springs and custom tuning are required.

FAQ
What engine does the Texas Speed Stage 3 LS7 cam fit?
It is ground for the naturally aspirated GM 7.0L LS7 found in the 2006 to 2013 Corvette Z06 and the 2014 to 2015 Camaro Z/28. Texas Speed designed it on a factory LS7 with no other internal changes.
What makes the Stage 3 LS7 lobes different?
Texas Speed custom ground the lobes specifically for the LS7 to make power through the whole rpm band while being more stable than comparable camshafts, which it says gives a quieter and longer lasting valvetrain.
How does the Stage 3 LS7 cam compare to the Stage 2 and Stage 4?
Stage 3 is 240/252 with .657"/.655" lift on a 111 LSA and a 2,800 to 6,900 rpm power band. Texas Speed's Stage 2 is smaller at 234/246 with .635" lift on 112.5 LSA, and Stage 4 is larger at 248/260 with the same .657"/.655" lift on 111 LSA and a 3,000 to 7,000 rpm band.
Is the Stage 3 LS7 camshaft streetable?
Texas Speed rates it race/aggressive with a lopey, aggressive idle. It pulls hard through the mid and upper rpm range, and custom tuning is required to run it.
Do I need valve springs with the Stage 3 LS7 cam?
Yes. Upgraded valve springs are required because the Stage 3 lifts the valves .657" on the intake and .655" on the exhaust with the factory 1.8:1 LS7 rockers.
