Crane camshaft identification

Thread Tools. March 10th, , PM. MO Olds I have a camshaft I am trying to identify that came with a bunch of parts but already sent the motor to the machine shop before I could check it. Anyone have a link to profiles or online catalog for Crane Cams that would provide specs? Appears they were bought out by Comp Cams. I believe it might be an old 'Fireball' or 'Commander' series. Any info appreciated! View Public Profile. JIM'S w

The world of high performance engines can be a very confusing place, where terms and specifications seem to be full of obscure references that appear to make no sense. But just like learning a new language, if you break each one down into smaller pieces, everything becomes easier to understand. One area of confusion is certainly a camshaft timing card. All aftermarket and production camshafts use a series of terms and specifications to identify their operating characteristics. These may seem obscure and even perhaps baffling, but in fact these cam specifications lay out a simple way of determining exactly how a particular camshaft will operate in the engine. A camshaft is really a device used to convert rotating motion into linear up and down movement. This is accomplished by use of a cam follower or lifter that starts on the round portion of the eccentric, which is called the base circle. As the cam lobe turns and the lifter follows the rise of the eccentric, the lifter moves upward, converting this rotating motion into an upward movement connected by the pushrod to the rocker arm. This simple upward movement of the cam lobe can be measured in terms of inches or millimeters of lobe lift.

Their profiles have been smoothed by computers for increased valve train life and added performance. One of these camshafts would be an awesome choice for a true restoration. Crane makes Blueprint camshafts for almost, if not, every GM, Ford, Mopar engine from the sixties and seventies. If you are confused as to which cam you should buy for your beast, Crane has you covered. They took the time to create a muscle car camshaft guide which can be found here. The guide even tells you what the factory part number for that particular camshaft is, along with their part number, lifter type, and all of the durations. These Blueprint Series Camshafts were designed for high compression ratio engines using high octane gasoline and they were also being used in cars with low end gear ratios. When building your motor, be sure to make the proper adjustments needed for the application.
