Product Details

The COMP Cams Thumpr 35-600-8 is a hydraulic roller camshaft engineered specifically for Ford 351 Windsor engines, delivering aggressive performance with a distinctive idle sound. This cam features 227/241 degrees of advertised duration with a .501"/.510" lift profile, creating substantial power gains in the 1,500-5,800 RPM range while maintaining excellent street manners.

Key Features:

  • Hydraulic roller design eliminates the need for constant valve lash adjustments
  • 227/241 advertised duration (intake/exhaust) optimized for street/strip performance
  • .501"/.510" valve lift delivers strong mid-range torque and top-end horsepower
  • 112-degree lobe separation angle produces aggressive exhaust note and solid vacuum
  • Compatible with factory fuel injection and aftermarket carbureted setups
  • Designed for Ford 351W small block engines (1969-1997)
  • Works with stock or aftermarket roller lifters and valve springs (verification recommended)

The Thumpr series is renowned for its aggressive lope at idle combined with strong street performance characteristics. This cam requires proper valvetrain components including compatible roller lifters, appropriate valve springs, and pushrod length verification for optimal performance and reliability. Recommended for engines with 9.0:1 or higher compression ratio and performance exhaust systems.
