Disappointing Performance Camshaft for Automotive Use

This camshaft failed to deliver the performance boost that was advertised. Installation was difficult and required professional help.

Pros
  • None
Cons
  • Poor performance, difficult installation.

good choice for 7.4 marine engines

bought this cam along with matching 911-16 springs but I used Crower Cam Saver lifters. The rotating assembly balanced. My dyno equipment was rated at 418 hp. at 5300 rpm and 475 ftlb of torque at 3500 rpm.

Pros
  • Designed for applications where low idle speeds are required and increased power helps maintain top speed over long distances.
Cons
  • Modernity
