Product Details

The COMP Cams 11-825-9 is a high-performance solid roller camshaft engineered specifically for drag racing applications in Chevrolet Big Block engines ranging from 396 to 454 cubic inches. This aggressive camshaft delivers a 272/280 duration profile designed to maximize horsepower and torque in competition environments where high-RPM performance is critical.

Key Specifications:

  • Intake Duration: 272 degrees
  • Exhaust Duration: 280 degrees
  • Solid roller lifter design for maximum valve control and reduced friction
  • Purpose-built for drag racing and high-performance street/strip applications
  • Compatible with Chevrolet Big Block V8 engines (396, 402, 427, 454 cubic inch)

Performance Characteristics:

  • Aggressive lobe profiles deliver substantial horsepower gains in the upper RPM range
  • Solid roller design eliminates lifter pump-up at high engine speeds
  • Optimized for maximum acceleration and quarter-mile performance
  • Requires matching solid roller lifters, heavier valve springs, and proper valvetrain components (sold separately)

This camshaft is ideal for serious racers seeking maximum performance from their big block Chevy engine. Professional installation and proper valvetrain setup are essential to achieve optimal results and engine longevity. This cam will produce a rough idle and is not recommended for emissions-controlled street vehicles.

Experience has been great. Best price and fast shipping. Thank You

Autoplicity was quick and easy to order from. I found just what I was looking for in absolutely no time at all, plus it was shipped extremely quickly. I would definitely order from this site/company again.<br><br>Thanks!

Fast shipping, product was excellent .

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.

Smooth transaction, very pleased

They made a mistake with the shipping address, but, they took care of it very politely and professionally. Very nice. Thanks.

quick turn around great price
