Overview
Redline Engine Supply bundles the Texas Speed Magic Stick cam with a matched valvetrain for Vortec LS engines. The kit pairs the grind with roller lifters, dual springs, steel retainers, a billet timing set and hardened chromoly push rods.
The billet timing set allows the cam to be advanced or retarded for tuning, and the spring pressures are published in full. The seller states that a professional tune is needed, and that automatic trucks need a looser torque converter, so budget time for that work beyond the parts.
Who it's for
Street and strip builders with a Vortec LS engine across the stated displacement range and a tuner on call. Owners of automatic trucks who want to keep the stock converter, or anyone skipping a tune, should choose a milder cam.
Pros and cons
- Spring pressures fully published
- Billet timing set for cam advance
- Roller lifters included
- Chromoly push rods supplied
- Professional tune is required
- Automatics need a larger stall converter
- Piston to valve clearance must be checked
Performance notes
The grind opens the valves wide and for a long time, which moves the powerband to higher engine speed. The seller recommends a taller rear gear and a high stall converter on automatics, because the cam needs rpm to work, and the tune sets timing and fuel to match.
