What kind of idle can I expect with this camshaft?

This COMP Cams XE274H1 camshaft is designed for aggressive performance, which typically results in a rougher idle compared to a stock camshaft. This is a common characteristic for performance cams that prioritize mid-range power and throttle response.

What is included in this cam and lifter kit?

The kit includes the camshaft itself, a set of hydraulic lifters, assembly lube to aid in installation and initial break-in, and decals. You'll have the essential parts needed to perform the camshaft upgrade.

Can this camshaft be shipped to California?

No, this camshaft is not CARB approved and cannot be shipped to California due to emissions regulations.

Product Details

This is the COMP Cams Xtreme Energy XE274H1 hydraulic flat tappet camshaft and lifter kit, designed for AMC V8 engines ranging from 290 to 401 cubic inches. If you're looking to significantly improve your vehicle's mid-range power and throttle response, this kit is a solid option. It's engineered to give you that extra punch when you need it, especially in the 2200+ RPM range, making it suitable for applications requiring a higher stall torque converter.

When you install this kit, expect a noticeable increase in performance, particularly in the mid-range. The XE274H1 camshaft profile is known for its aggressive nature, which contributes to its strong performance gains. However, this aggressiveness also means you'll experience a rougher idle compared to stock, which is a common characteristic of performance cams like this one. The kit comes complete with the camshaft, lifters, assembly lube, and decals, so you have the essential components for installation.

This kit is a popular choice for AMC enthusiasts looking to extract more performance from their classic V8s. Remember that this camshaft is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's instructions for proper installation and break-in procedures to ensure optimal performance and longevity.
