Product Details

The COMP Cams 12-651-20 is a high-performance solid flat tappet camshaft specifically designed for oval track racing applications in Chevrolet small block engines. This camshaft features a nitride finish for enhanced durability and wear resistance under demanding racing conditions.

Camshaft Specifications:

  • Duration: 248° intake / 250° exhaust (advertised duration)
  • Camshaft type: Solid flat tappet design
  • Application: Oval track racing
  • Surface treatment: Nitride coating for extended service life
  • Engine compatibility: Chevrolet small block V8 engines

This camshaft is engineered to deliver strong mid-range to upper RPM power characteristics ideal for circle track racing. The nitride treatment provides a hard, wear-resistant surface that reduces friction and extends camshaft life in high-stress racing environments. Requires matching solid lifters, appropriate valve springs, and proper break-in procedures for solid flat tappet camshafts.

Fast service and shipping, Plus the lowest price for the high performance k&n air filter<br>I wanted.

very fast processing received product within a few days. fair prices. will do business with again.

Easy steps go follow. I had a couple of hiccups in registering but overall it went well.

I was hesitant to order from Autoplicity due to the perception that the price was too good to be real (and not some scam). However, I read a few reviews on the internet and decided to take a chance. Once I placed my order I was sent a tracking number and received my car parts within 2 weeks. I was happy that I got the parts I ordered and the price was really low. Simple and quick.

Completely amazed by this seller. I recieved the rack in just 2 days and the price was unbeatable. I'm just stoked to have finally found a bike rack worth having!!
