Product Details

The COMP Cams 35-781-9 is a high-performance solid roller camshaft engineered specifically for drag racing applications in Ford 351 Windsor engines. This aggressive cam features 278 degrees of advertised intake duration and 286 degrees of advertised exhaust duration, delivering exceptional top-end horsepower and maximum rpm capability for competitive racing.

Key Specifications:

  • Intake Duration: 278 degrees advertised
  • Exhaust Duration: 286 degrees advertised
  • Valve Lift: Optimized for high-rpm performance with roller lifters
  • Solid Roller Design: Zero lash adjustable for maximum valve control and durability
  • Application: Ford 351 Windsor small block engines

Performance Characteristics:

  • Designed for dedicated drag racing and high-rpm competition use
  • Requires solid roller lifters, performance valve springs, and retainers
  • Best suited for engines with aftermarket heads, intake, and exhaust systems
  • Produces aggressive idle and maximum power above 3,500 rpm
  • Not recommended for street use due to radical profile and maintenance requirements

This camshaft is part of COMP Cams' Drag Race series, developed through extensive dyno testing and track validation. Proper installation requires checking piston-to-valve clearance and using compatible valvetrain components rated for the cam's lift and spring pressures.

<br><br>Borgeson 000940<br><br>I found Autoplicity during a price search on the Borgeson steering shaft for my truck. I had never heard of them, and was a bit skepticle. But after doing some research, found that Autoplicity has a good reputation on a Jeep forum I visit.<br><br>I decided to order, and I am impresed. Extremely fast shipping, I placed my order on Saturday, and its now Monday before noon. I am holding the new part!

Best price around. Great Communication. Fast shipping. What else can I ask for?<br>I have already purchased again from them.

Quick shipping and they had the fuel jugs I needed for the best prices thanks!<br><br>UPDATE: they were so good I made another order with them within a week.

thanks

Ordered on a Sunday night and technically took 6 business days instead of 3 to 5. Everything looks good so far.

Great Pricing (lowest i can find anywhere) and Quick Shipping, Product has no damage from shipping! Thank you Autoplicity!

I received my ARP head studs as described and on time with zero problems, and cheaper than anywhere else.Will use again!!!

We ordered a cover for a pickup truck bed and were so pleased that it was shipped so quickly. The price was the lowest that we found on the internet or in any of the stores where we looked. We were notified by e-mail as soon as it shipped. We will definitely shop this site again.

First time buyer from Autoplicity and found the website easy to navigate and find what I wanted quickly. They had the best price of all the other sites I checked, including shipping.
