Product Details

The COMP Cams 12-519-5 is a high-performance solid flat tappet camshaft designed specifically for drag racing applications in Chevrolet small block engines. This aggressive camshaft delivers exceptional top-end power and maximum rpm capability for competitive racing environments.

Camshaft Specifications:

  • Advertised Duration: 274° intake / 282° exhaust
  • Duration at .050": 224° intake / 230° exhaust
  • Valve Lift: .454" intake / .472" exhaust (with 1.5 ratio rockers)
  • Lobe Separation Angle: 110°
  • Solid flat tappet design for maximum durability and adjustability
  • Optimized for 2500-7000 RPM operating range

Key Features:

  • Race-proven profile engineered for maximum quarter-mile performance
  • Aggressive timing events produce hard-hitting acceleration and strong top-end power
  • Solid lifter design allows precise valve train adjustment and maintains zero lash at high RPM
  • Compatible with stock or aftermarket cylinder heads, intake manifolds, and headers
  • Requires aftermarket valve springs, performance lifters, and proper valve train components

This camshaft is ideal for dedicated drag race engines with high-compression pistons, ported heads, and open exhaust systems. Requires manual transmission or high-stall torque converter (3000+ RPM recommended). Not suitable for street use due to rough idle and minimal vacuum production.

I reciently ordered some spark plug wires from Autoplicity and I must say it was a great experience. The shipping was fast and they had the best price I could find. I will def order parts for my truck from them again.

Ordered Sunday and recieved product Tuesday .. What more can u ask for? Great Seller!

Easy and fast

I am very, very satisfied with my order. I ordered a Tonneau cover. It was a 35 lb. package and there was NO shipping cost to me. Plus it was received 3 days after my order. I searched many other websites and Autoplicity had the best pricing.

First time customer and I'll be back! Great prices, and rediculously fast shipping. Ordered Sunday night, delivered Wednesday morning. Couldn't ask for better service.
