Product Details

The COMP Cams 12-517-5 is a high-performance solid flat tappet camshaft engineered specifically for drag racing applications in Chevrolet small block engines. This aggressive profile features a tight lash design optimized for maximum power output in competition environments.

Camshaft Specifications:

  • Advertised duration: 266° intake / 274° exhaust
  • Solid flat tappet design for race applications
  • Tight lash specification for precise valve control
  • Purpose-built for drag racing and high-RPM performance
  • Direct replacement for Chevrolet small block V8 engines

This camshaft delivers an aggressive profile suited for dedicated drag race builds where maximum horsepower and torque are the primary goals. The solid flat tappet design provides durability and consistent performance under extreme racing conditions, while the tight lash specification ensures optimal valve train control at high engine speeds. Proper valve train components, including heavy-duty pushrods, performance valve springs, and quality lifters are required for installation.

<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.

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!!!

Bought a sparco steering wheel. Best price on the net. And shipping was very fast. Thank you

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.
