COMP Cams Camshaft CS X4 270HR-11

If you're looking to get more mid-range power out of your 1987 and newer Chevrolet or Buick small block V8 with a factory roller camshaft, this COMP Cams Xtreme 4x4 camshaft is a solid option. It's designed to work with OE roller lifters and is a popular choice for trucks and performance street applications that see a lot of use in the 2000-5500 RPM range.

This camshaft features a 220 intake and 224 exhaust duration at .050 lift, with a 111-degree lobe separation angle. This setup gives it a noticeable idle, which is part of the aggressive sound many enthusiasts look for in a performance build. For best results, COMP Cams recommends pairing this camshaft with headers, 3.55 to 4.10 rear end gears, and a torque converter with at least a 2000 RPM stall speed. It's built for OE roller SBC engines, excluding LT-1 and LS1 variants.

This camshaft fits a wide range of vehicles from 1987 onwards, including popular models like the Chevrolet Camaro, Corvette, and C/K series trucks. It's a well-built component designed to wake up the mid-range torque on your small block Chevy.
