Product Details

The COMP Cams 51-245-4 Magnum camshaft is a high-performance solid flat tappet cam designed specifically for Pontiac V8 engines ranging from 265 to 455 cubic inches. This camshaft delivers a balanced combination of mid-range torque and top-end horsepower, making it an excellent choice for street performance and weekend bracket racing applications.

Camshaft Specifications:

  • Advertised Duration: 236° intake / 236° exhaust
  • Duration at .050": 284° intake / 296° exhaust
  • Valve Lift: .454" intake / .480" exhaust (with 1.5:1 rocker ratio)
  • Lobe Separation Angle: 110°
  • Solid flat tappet design for maximum durability and performance
  • Idle RPM range: 1,800-5,600 RPM

Key Features:

  • Precision ground on COMP Cams' proprietary CNC cam grinders for exact lobe profiles
  • Compatible with factory or aftermarket cylinder heads
  • Requires adjustable valve train components
  • Designed for use with 9.5:1 to 11.0:1 compression ratios
  • Works well with single-plane or dual-plane intake manifolds
  • Produces a noticeable performance idle with good street manners

This camshaft is ideal for Pontiac enthusiasts looking to upgrade from a stock cam while maintaining reasonable street drivability. Best results are achieved when paired with performance cylinder heads, headers, and a free-flowing exhaust system. Professional installation and proper break-in procedures are recommended for solid flat tappet camshafts.

Very satisfied! My intake shipped on Friday and I received it on Tuesday. Not only super fast shipping, but a great deal to boot!

Great choices, quick checkout, great prices compared to competitors

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.

I entered my discount code 2offtotal and it did not remove 2% of the price. It was less than10 so not a big deal, but it would have been better if it worked.

Very good customer service asked about a lot of different springs and parts for my Mazdaspeed 3.
