Product Details

The COMP Cams Xtreme Energy 31-246-3 is a hydraulic flat tappet camshaft designed specifically for Ford small block 221-302 cubic inch V8 engines. This camshaft delivers a significant performance upgrade over stock with its 230/236 degree advertised duration, providing an excellent balance of increased horsepower and torque while maintaining good street manners and vacuum for power brakes.

Camshaft Specifications:

  • Advertised Duration: 230° Intake / 236° Exhaust
  • Duration at .050": 270° Intake / 276° Exhaust
  • Valve Lift: .477" Intake / .480" Exhaust (with 1.6:1 rocker ratio)
  • Lobe Separation Angle: 110°
  • Recommended RPM Range: 1,500-5,500 RPM
  • Recommended Valve Springs: COMP Cams #986 or equivalent

Performance Characteristics:

  • Ideal for street performance applications with manual or automatic transmissions
  • Produces a noticeable performance idle with good vacuum characteristics
  • Works well with stock or mildly modified cylinder heads
  • Compatible with stock torque converters and rear axle ratios
  • Requires hydraulic flat tappet lifters (not included)

This camshaft is part of COMP Cams' Xtreme Energy series, which features advanced lobe profiles designed to maximize performance across the RPM range. The asymmetric lobe design provides quick valve opening for excellent airflow while maintaining controlled closing rates for valvetrain stability. Professional installation is recommended, along with proper break-in procedures for flat tappet camshafts.

Great Price on products and Shipping

Fast shipping, Good communication, Highly recommended.!!!

quick delivery of the parts I need to fix my jeep

Could not find the part I was looking for at any other 4x4 website. Found it here and it was cheaper than almost every other place. Since I saved some I went ahead and paid the extra for 2-day shipping and still came out on top price wise. Definitely will be checking here again for parts for my Jeep!
