Product Details

The COMP Cams 35-780-9 is a high-performance solid roller camshaft engineered specifically for drag racing applications in Ford 351 Windsor engines. This aggressive cam profile delivers maximum power in the upper RPM range, making it ideal for dedicated race engines where ultimate performance takes priority.

Camshaft Specifications:

  • Advertised Duration: 268° intake / 275° exhaust
  • Duration at .050": 230° intake / 237° exhaust
  • Valve Lift (with 1.6 ratio rockers): .612" intake / .620" exhaust
  • Lobe Separation Angle: 110°
  • Solid roller design for high-RPM stability and durability
  • Optimized for maximum power between 4,000-7,500 RPM

Key Features:

  • Designed for naturally aspirated drag race engines with aftermarket heads and induction
  • Requires high-ratio rocker arms, performance valve springs, and upgraded valvetrain components
  • Best suited for engines with 10.5:1 or higher compression ratio
  • Not recommended for street use due to rough idle and poor low-RPM characteristics
  • Requires professional installation and valvetrain setup

This camshaft is part of COMP Cams' proven Drag Race series and requires matching solid roller lifters, performance valve springs, and a high-volume oil system to ensure reliable operation at high RPM. Professional engine building experience and dyno tuning are strongly recommended for optimal results.

Excellent place to deal with. I am a returning customer and love the fast shipping!!

First time buyer. Ordered Sunday. Shipped out Monday. Fast Shipping. Good prices.

Bought some wire looms for my Chevy from them. Great price, service, and shipping speed!

- Updated review -<br>Autoplicity.com contacted me after my original review and admitted to making a mistake with my order. They have refunded my shipping and I am happy now.<br><br>- Original review -<br>After 18 days the part finally arrived. The filter appears to have been sent directly from K&N, but I ordered on the 20th of June, yet the packing date that K&N Engineering Inc. shows is July 3rd.

The correct product that I ordered, and easy to find through there web site.thanks

Best price online for an Injen intake. Arrived in a week. Appreciated the "Item shipped" email with tracking number!
