What kind of idle can I expect with this camshaft?

This COMP Cams Xtreme Energy camshaft is designed for performance street machines and will produce a slightly rougher idle compared to a stock camshaft. This idle characteristic is typical for performance cams and signals an improvement in engine breathing.

What stall speed torque converter do I need for this camshaft?

For this XE268H-10 camshaft, a torque converter with a stall speed of 1800 RPM or higher is recommended. This ensures the engine stays within its power band during initial acceleration and low-speed driving.

Is this camshaft compatible with my stock valve springs?

This camshaft is a hydraulic flat tappet design. While it is designed for a range of Oldsmobile V8s, it's always best to check the manufacturer's specifications or consult with a professional to ensure compatibility with your existing valve springs and other valvetrain components.
