The Texas Speed Stage 2 LT1/LT4 3-Bolt Camshaft, No VVT is the street performance grind in the Texas Speed 3-bolt LT lineup for Gen V 6.2L LT1, LT4 and L86 engines that have had the factory variable valve timing removed. The 3-bolt core and TSP timing gear eliminate the phaser limiter and timing guesswork, and the cam delivers a lopey idle for street/strip or track use.
The cam measures 227/242 duration at .050", .646"/.631" lift, 112 LSA and 109.5 ICL with a +32 percent fuel lobe. It is compatible with factory-style pistons, and Texas Speed developed and validated it on its SuperFlow 902 engine dyno for piston-to-valve clearance. AFM/DOD is not supported, so a delete kit is required, and automatics need a higher stall torque converter. Texas Speed requires its .660" dual spring kit with PAC springs and titanium retainers and TSP chromoly pushrods. A custom tune is required after installation.

FAQ
What engines does the Texas Speed Stage 2 3-Bolt No VVT cam fit?
It fits GM Gen V 6.2L LT1, LT4 and L86 engines that have been converted to a 3-bolt camshaft gear with VVT deleted, including the 2016 and newer Camaro SS and ZL1, 2014 to 2019 Corvette and Z06, CTS-V and 6.2L trucks and SUVs.
Does the Stage 2 3-Bolt cam work with stock pistons?
Yes. Texas Speed states it is compatible with factory-style pistons, and every TSP LT camshaft is validated on the SuperFlow 902 engine dyno for piston-to-valve clearance. Final compression depends on the piston and head combination.
What parts are required to run the Stage 2 3-Bolt LT cam?
Texas Speed requires its .660" dual spring kit with PAC springs and titanium retainers, TSP chromoly pushrods and a DOD/AFM delete kit, plus the 3-bolt VVT delete conversion. Automatics need a higher stall converter and a custom tune is required.
Why choose a 3-bolt cam over a 1-bolt VVT cam?
The 3-bolt core replaces the factory phaser with a fixed TSP timing gear, so there is no phaser limiter to install and no VVT alignment to manage. Texas Speed offers the same 227/242 profile as the 1-bolt LT1 Stage 2 V2 for engines keeping the phaser with a lockout.
How does the Stage 2 3-Bolt compare to the EL-C7 3-Bolt cam?
The Stage 2 3-Bolt is 227/242 with .646"/.631" lift on a 112 LSA for street performance. The EL-C7 3-Bolt is the larger 231/245, .645"/.631", 112 LSA grind rated for race and aggressive use. Both need a DOD delete, .660" springs and a higher stall in automatics.
