Overview
Not a general LS part, this kit is made around one engine and the cars that carry it. It pairs the BTR Stage 2 V2 cam with sixteen roller lifters, a billet double roller timing set, dual springs, hardened push rods and valve stem seals.
The seller says the cam adds power in a naturally aspirated LS3 and changes the feel from the first throttle stab. Because a tune is required and automatics need a higher stall converter, the cam is a project rather than a bolt on change.
Who it's for
LS3 owners in the named cars who plan a professional tune and want one kit with the valvetrain matched to the cam. Owners of smaller LS engines or of a daily driver with a stock converter should look at other options.
Pros and cons
- Roller lifters and billet timing included
- Dual springs with retainers and locks
- Valve stem seals supplied
- Built for named LS3 vehicles
- Professional tune is required
- Piston to valve clearance must be checked
- Stall converter advised for automatics
Performance notes
The longer duration and higher lift move more air through each cylinder, and the seller reports a broad, aggressive powerband. The springs and push rods are chosen to control the valves at that lift, while the tune matches fuel and timing to the change in airflow.
