Product Details

The COMP Cams 12-650-5 is a high-performance solid flat tappet camshaft specifically engineered for oval track racing applications in Chevrolet small block engines. This camshaft delivers aggressive valve timing with 244 degrees of intake duration and 246 degrees of exhaust duration, providing excellent mid-range to top-end power characteristics ideal for circle track competition.

Key Features:

  • Solid flat tappet design for high-rpm durability and racing reliability
  • 244° intake / 246° exhaust duration for optimal power band
  • Engineered specifically for oval track racing demands
  • Compatible with Chevrolet small block V8 engines (262-400 cu. in.)
  • Requires solid lifters, performance valve springs, and pushrods (sold separately)
  • Designed for use with aftermarket cylinder heads and higher compression ratios

This camshaft is intended for dedicated race engines and requires proper break-in procedures with zinc-fortified oil. Professional installation and valve train setup is recommended to ensure optimal performance and longevity. Not intended for street use or emissions-controlled applications.

Fast shipping on purchased item. Had in stock when other's did not.

love the amazon payment option

excellent service, i had to wait a few days for the order to be processesed, but only because i ordered on Friday afternoon, but love the site!

I ordered a hitch off of this site for Christmas, I have never heard of it nor did I know how they were, but they are great! Got my package in I'd say 4 days, very fast and it was exactly what I wanted! Only down fall was they charged me 3 times and I was short 150$ for a few days. I got my money back and I would definitely order again.

Great price. Easy to navigate site. Not Autoplicity's fault but the part I received is inferior to the original part. It works ok but if doesn't feel as solid as the original. The difference in quality is reflected in the price and I saved quite a bit going with a less expensive alternative.
