Product Details

The COMP Cams Xtreme Energy CL12-770-8 is a high-performance solid roller camshaft and lifter kit designed specifically for Chevrolet small block engines. This aggressive camshaft features 236° intake duration and 242° exhaust duration at .050" lift, delivering substantial power gains in the mid-range to upper RPM range.

Key Features:

  • Solid roller design for maximum valve control and high-RPM stability
  • 236°/242° duration at .050" provides aggressive performance characteristics
  • Optimized for street/strip applications and high-performance street builds
  • Engineered for Chevrolet small block V8 engines
  • Includes premium-quality solid roller lifters matched to camshaft specifications
  • Complete kit includes assembly lube, detailed installation instructions, and decals

This Xtreme Energy camshaft is ideal for enthusiasts seeking aggressive throttle response and substantial horsepower gains. The solid roller design eliminates the limitations of hydraulic lifters, allowing for higher valve spring pressures and more aggressive lobe profiles. Best suited for engines with aftermarket cylinder heads, intake manifolds, and exhaust systems. Requires compatible valve springs, pushrods, and timing set (sold separately). Professional installation and proper break-in procedures are strongly recommended for solid roller camshafts.

Very accurate service Thanks .

Great

Easy to navigate thru site, thanks Peter W

Everything was fine. Shipping could be a little faster though.

Awesome!

Had a really hard to find part in stock and delivery was a day earlier than expected. I'll be shopping here again.

easy

Autoplicity has a great selection of parts and wonderful customer service.

Best price and super fast shipping. Only issue was that their online order status system was really far behind! The system said my order was "pending" and it had been shipped. Later it said "processing" and it was on my doorstep. Not a big deal and certainly better than the opposite (they tell you something has happened when it hasn't) and doesn't keep them from being a 5 star seller in my book.

competitive prices and good selection. Will definitely look to this vendor when purchasing automotive parts in the future. I ordered a roof rack and it was very hard to find elsewhere and the few places I did find it, it was more expensive.. it was cheap and easy here. thanks :)
