The Chevy 348/409 Thumpr Hyd Cam from COMP CAMS is designed for big-block Chevrolet enthusiasts who seek an aggressive idle character while maintaining street drivability. This hydraulic roller cam is specifically built for 348 and 409 cubic-inch engines, making it an excellent choice for classic or vintage muscle cars.
The "Thumpr" designation signifies a distinctive loping exhaust note that enhances your vehicle's presence without compromising its usability on the street. Leveraging COMP CAMS' extensive cam grinding expertise, this design ensures precise valve timing and lift across the RPM range while minimizing wear on lifters and pushrods. The roller follower technology reduces friction compared to flat-tappet cams, allowing for higher lift and duration without sacrificing engine longevity.
Ideal for builders restoring or upgrading original Chevrolet big-blocks, this cam is perfect for street-strip applications where a noticeable attitude is desired without the limitations of track-only components. Installation requires careful valve train inspection and proper push-rod length verification to ensure optimal performance.
