Product Details

The COMP Cams 51-229-3 High Energy camshaft is engineered specifically for Pontiac V8 engines from 265 to 455 cubic inches. This hydraulic flat tappet camshaft delivers a 206/206 duration profile that provides excellent performance gains for street-driven Pontiac engines while maintaining smooth idle characteristics and vacuum for power accessories.

Camshaft Specifications:

  • Advertised Duration: 256/256 degrees
  • Duration at .050": 206/206 degrees
  • Valve Lift (with 1.5 ratio rockers): .420"/.420"
  • Lobe Separation Angle: 110 degrees
  • RPM Range: Idle to 5,000 RPM
  • Hydraulic flat tappet design for quiet operation

Key Features:

  • High Energy grind profile optimized for street performance and drivability
  • Symmetric intake and exhaust lobes for balanced power delivery
  • Compatible with stock valve springs and components in most applications
  • Ideal upgrade for street cruisers, daily drivers, and mild performance builds
  • Maintains good low-end torque while improving mid-range power
  • Direct replacement for Pontiac 265, 287, 301, 326, 350, 389, 400, 421, 428, and 455 engines

This camshaft is part of COMP Cams' High Energy series, designed to provide noticeable performance improvements over stock camshafts while maintaining excellent street manners. The moderate duration and lift make it an excellent choice for engines running stock or mildly modified cylinder heads, and it works well with automatic or manual transmissions.

The fellas at Autoplicity where great, very proffesional, and great price as well. I will definately be using them again. ohh, and super fast shipping... thank autoplicity...

Unbeliveable customer service and super fast shipping. I had a question about my order and I was able to use the online chat function to instantly connect with a customer service agent that was quick to answer all my questions regarding my order. I am very pleased with the level of service I received not to mention the great price they offered on the item I purchased. I will be sure to continue doing business with Autoplicity for my automotive needs. Thanks so much. A+

Best price for a product I've been shopping for, for months, and when I saw Autoplicity having it for A LOT cheaper, putting the product in my sweet spot price wise, I didn't hesitate to order. <br><br>My bank was a little slow to post the transaction, and I was suprised to get a human on the phone with no effort to make sure my order was properly processed. The gentleman I spoke with was very friendly and promptly answered all my questions. <br><br>Only the $5 I'm getting back for this review can make this deal any better, as I have no suggestion for improving the transaction I made with them.

best price i could find online. fast shipping

We ordered a cover for a pickup truck bed and were so pleased that it was shipped so quickly. The price was the lowest that we found on the internet or in any of the stores where we looked. We were notified by e-mail as soon as it shipped. We will definitely shop this site again.
