Product Details

The COMP Cams 12-628-5 is a high-performance solid flat tappet camshaft designed specifically for Chevrolet small block engines. This Max Area profile camshaft delivers aggressive valve timing with 252 degrees of advertised intake duration and 260 degrees of advertised exhaust duration, making it ideal for street/strip applications and high-revving performance builds.

Key Features:

  • Solid flat tappet design for maximum durability and performance
  • 252/260 advertised duration provides strong mid-range to high-RPM power
  • Max Area lobe profile optimizes valve area under the curve for improved airflow
  • Engineered specifically for Chevrolet small block V8 engines (262-400 cubic inches)
  • Requires matching flat tappet lifters, performance valve springs, and proper break-in procedure
  • Ideal for engines with aftermarket cylinder heads, headers, and performance intake manifolds

This camshaft is designed for enthusiasts seeking significant performance gains over stock, with a focus on maximizing power output in the 3,000-6,500 RPM range. Professional installation and proper break-in procedures are strongly recommended to ensure optimal performance and longevity.

Good

For as cheap as what I paid for my product I will admit I was scared!!! Got what I asked for in perfect condition, came fast and wonder where have you been all my shopping life? Thanx for such a great deal and fast shipping!!!

Incredible prices! I purchased a name brand leveling kit for 40% less than any one else is selling them for. Item shipped out within 2 days. Shipping cost is reasonable, and if you leave a review here after your purchase, they'll credit you back $5! BEST DEAL GOING!

I looked around for the best peice for a set of Sparco seats. I found them on autoplicity much cheaper then anywhere else. I figured it would take a few days to ship, but by the time i decided to call for a tracking #, I got an email with tracking # and that my seat was all ready to be delivered the next day. They didnt ship together because they were out of stock for a day or 2. I called about my other seat a few days later and it was already delivered at my door. Any future purchases will be checked with autoplicity 1st.

Great site. Provided needed technical specs. Shipped promptly. Although I had to ask for the tacking number, it was not emailed, one was provided promptly upon request.

Unbeleiveable!!!! Super fast shipping!! Great job!!! Keep up the good work!<br><br>P Savaria
