Overview
Michigan Motorsports lists this Texas Speed NSR RV camshaft for smaller displacement LS truck and street engines. The no springs required design lets the factory valve springs stay in place, and the polished cam is sold on its own.
A cam of this type suits a daily driver or work truck that needs more low end pull without a full valve train rebuild. The seller copy promises a smooth idle and better throttle response, but gives no lift, duration or timing figures, so power gains stay unquantified.
Who it's for
Truck owners towing or commuting with a small displacement LS engine who want a mild upgrade without new springs. Anyone chasing a high rpm build or needing a complete kit should look at another cam.
Pros and cons
- Retains factory valve springs
- Torque focused grind
- Covers many LS codes
- Lift and duration not listed
- Camshaft only, no kit
- Break-in steps not described
Performance notes
A cam profile sets how long and how far the valves open, and this one is tuned toward low engine speed torque and throttle response. Since the factory springs are retained, the profile has to stay mild enough for them to control the valves.
