The Texas Speed 5.3L L83 V2 Turbo Camshaft is part of the second-generation L83 lineup for GM Gen V 5.3L trucks and SUVs. Texas Speed redesigned the lobes of the V2 series for less lift and more power than the original L83 cams, which is easier on the valve springs and quiets valvetrain noise. This is the turbo grind of the family, for the enthusiast chasing a bigger jump in horsepower who accepts a rougher idle and an aftermarket converter. Its 32% fuel lobe supplies the additional fueling forced induction needs.
The cam uses the stock compression ratio and the TSP dual .660" spring kit. Texas Speed says the cam will need an aftermarket stall converter and recommends a 2,600 to 2,800 rpm stall. The operating range is 1,800 to 6,600 rpm. Because the cam does not retain AFM/DOD cylinder deactivation, a DOD/AFM delete kit is required, a camshaft phaser lockout is required, and a custom tune is required after installation.

FAQ
What engines does the Texas Speed L83 V2 Turbo cam fit?
Texas Speed lists it for the GM Gen V 5.3L L83 found in 2014 and later Silverado and Sierra 1500 and 2015 and later Tahoe, Suburban and Yukon. TSP's fitment filter also lists the later L84 and L82 5.3L engines.
Do I need a DOD delete kit with the L83 V2 Turbo camshaft?
Yes. The camshaft does not retain the factory AFM/DOD cylinder deactivation, so Texas Speed states a DOD/AFM delete kit is needed, along with tuning to disable AFM in the ECM.
Is a phaser lockout required for this L83 cam?
Yes. Texas Speed lists a camshaft phaser lockout as required for the L83 V2 Turbo, and its dyno testing was done with the phaser locked out.
How much power does the L83 V2 Turbo camshaft add?
Texas Speed does not publish a fixed number because the gain depends on turbo sizing, piping, boost level and the rest of the build. The cam is designed to support a turbocharged L83 rather than add a set amount by itself.
What converter does the L83 V2 Turbo cam need?
Texas Speed says the cam will need an aftermarket stall converter and recommends a 2,600 to 2,800 rpm stall. No rear gear upgrade is required according to Texas Speed.
What valve springs does the L83 V2 Turbo require?
Upgraded valve springs are required. Texas Speed specifies its TSP dual .660" spring kit for the L83 V2 cams, which were designed with less lift than the first-generation L83 grinds to be easier on springs.
