Powerful Upgrade for Performance Engines

As a result of my tests, I determined that this performance camshaft is an excellent choice for boosting horsepower and torque in high-performance engines. The improved throttle response and engine sound are sure to impress any car enthusiast. However, installation can be tricky and may require professional help for those without experience. Overall, this camshaft is a great investment for those looking to take their car's performance to the next level.

Pros
  • Increases horsepower and torque for high-performance engines.
Cons
  • For pensioners

A lot of bang for your buck

These Thumpr series cameras are really good. Okay, they give you a great aggressive exhaust note and idle and still deliver a good level of performance.

Pros
  • Crossing my fingers
Cons
  • Zero

Great sounding cam

This cam I have in big block 402 1971 with standard clutch pistons and 820 cast heads, chambered 113cc in fact it works very well. I have a 1993 c1500 long bed engine with 4:10 gearing and he woke the engine up immediately by running a Proform 650 race carb and a 2800 converter and it runs very powerfully. If you want an awkward sounding cam rather than a big caliper motor, the Thumpr cam is the way to go. Works best at a compression of 9 to 1 or higher.

Pros
  • Wide range
Cons
  • Negative impression
