Camshaft Tech with COMP Cams’ Billy Godbold
We caught up with Billy Godbold to discuss all things camshaft, from common misconceptions to proper camshaft selection to firing order and much more.
COMP Cams HRT Turbo & Supercharger Camshafts for Dodge Gen III HEMI Engines
The Gen III HEMI market is rapidly expanding and the HRT Camshaft Series uses the newest and most advanced lobe designs from COMP Cams in order to produce some of the highest average power and torque increases available.
COMP Cams LST & HRT Performance Camshaft Packages
LST & HRT Performance Camshaft Packages take the guesswork out of choosing the best valvetrain upgrade for your specific engine and desired performance. The Low Shock Technology behind these performance packages features lobe profiles designed to maximize horsepower, while improving stability at higher rpm. These profiles are also easier on the valve springs, enhancing durability and reducing load
Camshaft Art and Science – You Get Out What You Put In
The most misunderstood component of an engine is the camshaft. Selecting a camshaft and understanding its profile and design can be a “black art” as most of what a cam profile controls is invisible – air. Yet, the camshaft has a major impact on engine performance.

Camshaft Selection
“What camshaft should I use?” How many times have you been asked or heard that question uttered? Why is it so difficult to choose the “correct” camshaft for an engine build? What separates one camshaft design from the other? After all, isn’t it true that a camshaft opens and closes valves? Simple, right? Well let’s
Camshaft Class is Back in Session
A theory prevails in which a cam lobe that opens to maximum lift and closes instantaneously is quintessential for maximum power and torque operation. Two problems exist with this premise. First, it’s highly impractical due to current technology. Second, this theory discounts a fundamental dilemma that air has momentum, and this must be utilized to achieve
Choosing the Correct Camshaft – Bangin’ on the Bumpstick
There are numerous aspects involved in designing an engine combination. Displacement, compression, airflow, etc., and it is the camshaft’s job to ensure that all of these work together properly to achieve optimum performance. That’s why the cam is often referred to as the “brain” of the engine.
There’s No Simple Formula to Choosing the Perfect Camshaft
The camshaft design affects valve timing, compression and the engine’s ability to breathe. From pistons to manifolds, valve grind, piston pin offset, rod length, etc. Once the camshaft has been tabbed correctly for the application, the rest of the build can focus off that selection.
Edelbrock Rollin’ Thunder Camshaft For Chrysler Gen 2 Hemi Engines
Edelbrock has a new Rollin’ Thunder camshaft for Chrysler 426-572 Hemi engines. Edelbrock Rollin’ Thunder hydraulic roller camshafts are designed to improve horsepower and torque, produce a great sounding performance idle and provide sufficient vacuum.
Koenigsegg’s Camshaft-Free Engine
As opposed to a camshaft dictating valve position, each valve has its own actuator controlling the valve position and timing.
Camshaft Selection and Design
Choosing the right cam from all of the possibilities that are out there can make a significant difference in how well an engine performs. It’s all about balance and correctly matching the cam with the cylinder heads, compression ratio, intake and exhaust systems, and RPM range where you want the engine to produce the most torque and horsepower.
Edelbrock Performer-Plus Camshaft for EFI Systems
Edelbrock now offers a new Performer-Plus camshaft for use with throttle-body style Electronic Fuel Injection systems on a small-block Chevrolet. Edelbrock Performer-Plus camshafts feature profiles that deliver a major improvement in throttle response and torque from off-idle to 5,500 rpm.
Edelbrock Rollin’ Thunder Camshaft For Small-Block Chevrolet Engines
Edelbrock is now offering a new Rollin’ Thunder camshaft for small-block Chevrolet engines. Edelbrock Rollin’ Thunder camshafts are designed to improve horsepower and torque, produce a great sounding performance idle and provide sufficient vacuum.
Choosing the Right Camshaft for a Performance Engine
A camshaft is nothing more than a cast iron or steel shaft with a series of lobes strategically placed along its length. Each lobe opens and closes a valve by moving a lifter, pushrod and rocker arm, or in the case of an overhead cam engine by moving a cam follower or direct valve action. However, choosing the right camshaft is not only the cornerstone of building a performance engine, but also its centerpiece.
