Pro Torquer
LC Engineering's EFI Pro Torquer Camshaft is an excellent upgrade to any mild engine application. This cam is compatible with a carbureted or factory fuel injection setup. This cam is also designed to work with the factory valve train components so you will not have to upgrade springs, retainers, etc... This cam has an offset duration between the intake and exhaust side to create a strong low-end torque curve while still providing good pulling power up to 5,000 RPM.
LC Engineering is constantly striving to improve both the quality and performance of our products. We test our camshafts on the street, race track, and off-road. The results are an improved line of camshafts that offer a broader selection of grinds, increased horsepower, and higher quality. All LC Engineering Camshafts are ground on new billets and double heat-treated for long life. Each has been designed for maximum torque and horsepower, specifically for the application. When comparing camshaft profiles, always reference the duration @ .050" valve lift.

NOTE: LC Engineering will not warranty any cam damage if you do not purchase new Toyota rocker arms from LC Engineering, or a complete rocker arm assembly from LC Engineering at the same time as purchasing our camshaft.
- Individual rocker arms, see Part #: 1023015.
- Complete rocker assembly, see Part #: 1023018.
Buyer beware on reground rockers in the market. Regrinding the pad on the rocker can remove the heat treated portion of the pad making for a soft rocker. Rocker arms that are reground will not have the factory geometry of a stock rocker. To regrind a rocker will take care of the face surface but will do nothing to address the rocker shaft bore, a loose rocker bore will make adjustment difficult and will never be correct which is why we cannot warranty a camshaft unless new rockers are purchased with a camshaft.
This product should not be used in a manner that violates Federal EPA Laws.
