Product Details

The COMP Cams 11-718-9 is a high-performance solid roller camshaft engineered specifically for drag racing applications in Chevrolet big block engines (396-454 cubic inches). This aggressive camshaft delivers maximum power and torque for serious competition use.

  • Advertised Duration: 282° intake / 292° exhaust
  • Duration @ .050": Approximately 242° intake / 248° exhaust
  • Valve lift: Approximately .600" intake / .600" exhaust (with 1.7:1 rocker ratio)
  • Lobe separation angle: Typically 110°-112° for optimal power band
  • Solid roller design for maximum valve control and high-RPM stability
  • Requires solid roller lifters, upgraded valve springs, and pushrods (sold separately)

Performance Characteristics:

  • Designed for dedicated drag race engines with supporting modifications
  • Optimal power range: 3,000-7,500+ RPM
  • Requires minimum 10.5:1 compression ratio and aftermarket cylinder heads
  • Not suitable for street use due to aggressive profile and idle characteristics
  • Requires professional installation and valve train setup

This camshaft is intended for race-only applications and requires supporting modifications including upgraded valve train components, high-flow cylinder heads, headers, and high-stall torque converter. Professional installation and degree-in procedures are strongly recommended to achieve optimal performance and engine reliability.

Bought a Husky trunk liner for my Civic. Autoplicity had the lowest price I could find, plus I received it in two days. Only problem I had was that their website had a problem with the part fit check. Although the description and part number was for the 2012 Civic, the part check said it would not fit. Had to wait until Monday to call customer service to verify that it would fit before I ordered. Would definitely order from Autoplicity again.

easy to order, least expensive for same item selling elsewhere for up to50 more, plus shipping. Great site will use again

Reasonable shipping, quick checkout with amazon.

Very easy!!

I had been searching many sites for a better price on shocks for my 1999 Ford Explorer, upon finding Autoplicity the savings was 13.00 cheaper than all others. I instantly made the purchase. wish i had knew about them before I purchased the other items for my truck. will return as a customer .

Awesome service, Great price, Fast shipping.

efficient; loved payment through Amazon
