Product Details

The COMP Cams 11-720-9 is a high-performance solid roller camshaft engineered specifically for drag racing applications in Chevrolet Big Block engines (396-454 cubic inches). This aggressive cam profile delivers maximum top-end horsepower and torque for serious competition use.

Camshaft Specifications:

  • Intake Duration: 284 degrees
  • Exhaust Duration: 288 degrees
  • Solid roller design for maximum durability and performance
  • Optimized lobe profiles for drag racing applications
  • Designed for Big Block Chevrolet 396, 402, 427, and 454 engines

Performance Characteristics:

  • Aggressive lift and duration for maximum horsepower at high RPM
  • Solid roller construction eliminates hydraulic lifter limitations
  • Ideal for dedicated race engines with supporting modifications
  • Requires solid roller lifters, heavier valve springs, and proper valve train components

This camshaft is designed for race-only applications and requires professional installation with careful valve train setup, including proper lash adjustment, valve spring selection, and pushrod length verification. Not recommended for street-driven vehicles due to aggressive profile and high idle characteristics.

Easy, Cheap prices

Very satisfied! My intake shipped on Friday and I received it on Tuesday. Not only super fast shipping, but a great deal to boot!

I ordered a hitch off of this site for Christmas, I have never heard of it nor did I know how they were, but they are great! Got my package in I'd say 4 days, very fast and it was exactly what I wanted! Only down fall was they charged me 3 times and I was short 150$ for a few days. I got my money back and I would definitely order again.

I am very pleased with my purchase from Autoplicity. Price was very reasonable and shipping was great!

Very good customer service asked about a lot of different springs and parts for my Mazdaspeed 3.
