In our evaluation, this cam works well with stock Vortec heads when using 1.6 rockers, providing a nice power increase without excessive valvetrain stress. Owner feedback suggests it is a reliable choice for mild street builds, especially when paired with Edelbrock’s intake systems.
However, without 1.6 rockers, the cam is relatively tame and may not justify the upgrade cost. Additionally, the duration is moderate, so it won’t deliver the top-end power of more aggressive cams. If you already have 1.6 rockers or plan to install them, this cam is worth considering. Skip it if you prefer a cam that performs well with stock 1.5 rockers or want a more aggressive profile.
- Designed to work with stock 1.6 ratio rocker arms for increased lift
- Smooth idle and good vacuum for street use
- Compatible with Edelbrock intake manifolds and carburetors
Pros: Effective when paired with 1.6 rockers for extra lift; Good mid-range torque

Frequently Asked Questions
What is a roller cam and why should I use one with stock Vortec heads?
A roller cam uses roller lifters instead of flat tappets, reducing friction and allowing more aggressive lobe profiles. For stock Vortec heads, a roller cam can significantly increase horsepower and torque without major head modifications. It also improves throttle response and reliability.
Will a roller cam work with my stock Vortec heads without modifications?
Most roller cams in this guide are designed for stock Vortec heads, but you may need to check valve clearance. Some high-lift cams (above 0.530) may require notching the head or using thinner head gaskets. Always verify piston-to-valve clearance and valve spring compatibility.
Do I need to upgrade my valve springs when installing a roller cam?
Yes, it is highly recommended. Stock Vortec valve springs are not designed for the higher lift and faster ramp rates of roller cams. Upgraded springs prevent valve float and ensure proper valvetrain control. Most cam kits include suitable springs.
Will a roller cam affect my idle and vacuum for power brakes?
It depends on the cam’s lobe separation angle (LSA). Cams with 112 LSA or wider typically have a smooth idle and good vacuum. Narrower LSAs (110 or less) produce a choppier idle and lower vacuum, which may require a vacuum pump for power brakes.
Can I use a roller cam with a factory ECU and fuel injection?
Mild roller cams (up to 212 duration at 0.050) usually work with factory ECUs and fuel injection. More aggressive cams may require aftermarket tuning or a standalone ECU to optimize air/fuel ratios and idle control.
