The Texas Speed Stage 1 LT1/LT4 3-Bolt Camshaft, No VVT is the entry 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 pairs with a TSP timing gear, so no phaser limiter is needed and cam timing stays fixed, and Texas Speed rates it daily driver friendly with a mild chop.
The cam measures 222/236 duration at .050", .610"/.610" lift, 113 LSA and 109 ICL with a +32 percent fuel lobe. Texas Speed developed it on its SuperFlow 902 engine dyno using a stock 6.2L LT1 and checks every LT camshaft for piston-to-valve clearance. It does not support AFM/DOD, so a delete kit is required. Texas Speed's page for this version calls for a higher stall converter in automatics and recommends its .660" dual spring kit with PAC springs and titanium retainers and hardened chromoly pushrods. A custom tune is required after installation.

FAQ
What engines does the Texas Speed Stage 1 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.
Do I need a phaser limiter with the Stage 1 3-Bolt cam?
No. The 3-bolt cam core and TSP timing gear replace the factory VVT phaser entirely, so no phaser limiter or lockout is used. A 3-bolt conversion is required on the engine.
Is a DOD delete kit required with this camshaft?
Yes. The Stage 1 3-Bolt camshaft does not support factory AFM/DOD cylinder deactivation, so a DOD/AFM delete kit with non-AFM lifters is required.
Does the Stage 1 3-Bolt LT1 cam need a stall converter?
Texas Speed's page for this 3-bolt version states a higher stall speed torque converter is required for automatic transmissions. Note that the 1-bolt LT1 Stage 1 V2 with the same profile is listed as factory converter friendly, so confirm with Texas Speed for your combination.
What valve springs and pushrods does Texas Speed recommend?
Upgraded valve springs are required. Texas Speed recommends its .660" dual spring kit with PAC springs and titanium retainers along with TSP hardened chromoly pushrods.
How does the Stage 1 3-Bolt compare to the Stage 2 3-Bolt LT cam?
The Stage 1 3-Bolt is 222/236 with .610"/.610" lift on a 113 LSA and is rated daily driver friendly. The Stage 2 3-Bolt steps up to 227/242 with .646"/.631" lift on a 112 LSA for street performance use. Both require a DOD delete and the 3-bolt VVT delete.
