Product Details

The COMP Cams Xtreme Energy 12-234-2 hydraulic flat tappet camshaft is designed specifically for Chevrolet Small Block engines seeking improved performance across the RPM range. This camshaft features 212 degrees of intake duration and 218 degrees of exhaust duration at 0.050" lift, providing a noticeable increase in mid-range torque and horsepower while maintaining street-friendly idle characteristics.

Key Specifications:

  • Intake Duration: 212° @ 0.050"
  • Exhaust Duration: 218° @ 0.050"
  • Hydraulic flat tappet design for reduced maintenance
  • Xtreme Energy profile for enhanced throttle response
  • Designed for Chevrolet Small Block V8 engines
  • Recommended RPM range: 1,500-5,500 RPM

The Xtreme Energy series from COMP Cams utilizes advanced lobe profiles that deliver more area under the lift curve compared to traditional camshafts. This design provides stronger acceleration, improved vacuum for power braking, and better fuel economy than competitors' camshafts with similar duration specs. Ideal for street performance applications, daily drivers, and mild street/strip builds.

Note: Requires compatible hydraulic flat tappet lifters, pushrods, and valve springs (sold separately). Professional installation and proper break-in procedure recommended.

Great service! A+++++++++

Great price and super fast shipping.

I just finished a transaction with this company and decided to write my very first post, based upon my experience with them. To be honest, a few short hours ago I was wary of how this would turn out. There had been a miscommunication with shipping and it started to go down hill. Lo and behold, something happened that is rare today. The company, from top to bottom put all of their efforts together, communicated with me even during a Holiday and rectified the situation. Not only would I recommend Autoplicity to others but implore potential customers to use them confidently. Their work ethics and customer service is top notch and I am very grateful for my renewed trust that there is more than just big box, fast food companies out there. Thank you again!!

excellent ship time and exceptional pricing deffinatly will buy from here again

Wow it was shipped so quickly it arrived the next day. Will be ordering again.

Good price, the only decent place I could find this part online.

Very cheap prices compared to most other performance markets.
