Product Details

The COMP Cams Xtreme Energy XFI 12-365-4 is a hydraulic flat tappet camshaft engineered specifically for Chevrolet Small Block V8 engines. This performance camshaft features 216 degrees of intake duration and 223 degrees of exhaust duration (measured at .050" lift), delivering a noticeable increase in mid-range power and torque over stock camshafts.

Key Specifications:

  • Intake Duration: 216 degrees @ .050"
  • Exhaust Duration: 223 degrees @ .050"
  • Hydraulic flat tappet design for reliable operation
  • Designed for Chevrolet Small Block engines (262-400 cubic inches)
  • Ideal RPM range: 1,500-5,500 RPM
  • Lobe separation angle optimized for street/strip performance

Performance Benefits:

  • Improved throttle response and acceleration
  • Enhanced mid-range torque for better street drivability
  • Smooth idle characteristics suitable for street use
  • Compatible with factory valve springs in most applications

The Xtreme Energy XFI series from COMP Cams utilizes advanced lobe profiles to maximize performance while maintaining excellent streetability. This camshaft works well in engines with compression ratios between 9.0:1 and 10.5:1 and pairs effectively with aftermarket intake manifolds and headers. Proper break-in procedures with high-zinc oil or COMP Cams break-in additive is required for hydraulic flat tappet camshafts.

Good price & easy check out

The ordering process went really smoothly. Got my ordering info e-mailed smartly and was able to track the order easily. Looking forward to using my item as soon as it gets here!

Had to upgrade to a Snell 2010 helmet this year, bought the identical helmet for $200 less than I paid 8 years ago! Fast shipping, I will be checking Autoplicity first in the future!
