This catalog is organized into three separate sections. First is the Cam & Valve Train Application pages which includes all of the necessary information needed to choose the right camshaft for your needs. Next is the Cam & Valve Train Buyer’s Guide. The Buyer’s Guide contains additional product applications and additional information not found on the regular applications pages. The final section is the Ignition and Ignition Buyer’s Guide pages.
Each product section is organized in alphabetical order, and in “Make, number of cylinders, year, engine” fashion. Cam & Valve Train Applications are organized in alphabetical order, by engine make. Cam profiles (“grinds”) are listed beginning with the “mildest” duration (lowest numerical duration shown at .050” cam lobe lift) through the “wildest” duration figures.
Catalog Sections Cam & Valve Train Applications: Pages 20–263 Valve Train Buyer’s Guide: Pages 264–350
Choosing the Correct Cam All Crane Cams are organized in typical “Make, number of cylinders, year, engine” fashion, and according to the type of lifter used... Hydraulic, Hydraulic Roller, Mechanical (Sometimes called “solid” or “flat tappet”), and Mechanical Roller. Cam profiles (“grinds”) are listed beginning with the mildest duration through the most radical in each lifter type.
Each left page begins with the Application column. This column gives basic application information. In the next column is the Cam Series and Grind Number. Next is the RPM Power Range, and then the cam Part Number. “Cam Only” cams usually have a suffix (last) digit “1” in the part number. Cam & Lifter Kits usually have a “2” digit suffix. Application provides additional information about the camshaft. If the idle quality is other than stock, it is also noted in this column. Cam specs data such as valve lift, duration and lobe separation is shown at the far-right of each cam listing. To choose a street performance cam refer to “Choosing The Right Cam”, and “Getting Information”, found on pages 11 and 12–13. Note the part number of the cam you select.

Crane Cams History
Crane Cams was originally known as known as “Crane Engineering Company, Inc.”, and was founded on January 1st, 1953. In 1970 the original name, “Crane Engineering”, was shortened to “Crane Cams, Incorporated”, better defining the company’s products and market of that era.
From that very humble beginning, Crane Cams has evolved into a manufacturing and marketing company. Amazingly, it all began in an unused corner of the company owned by the founder’s father’s machine shop.
The founder, a young apprentice machinist, became interested in “souping- up” his flathead Ford V-8 hot rod. Like most others, he was strongly influenced by the various “hot rodding” magazines, ordering his first cam from a California cam company’s ad. The founder’s machinist’s training and hot-rodder’s ingenuity had already taught him that camshaft design and accuracy exacts a critical effect on engine power. He also knew he was easily capable of designing and manufacturing camshafts. What’s more, he knew he could design more
powerful, far more accurate and repeatable camshafts.
Although money was scarce, the young apprentice traded his way into a well- used cylindrical grinder. In rebuilding this old, used machine he quickly developed cam manufacturing and design knowledge. His initial “home made” cams were accurately made and surprisingly more powerful than anything he’d previously purchased. Other local hot rodders soon found out, and began buying his camshafts. The reputation of the backroom Crane cam company spread quickly across Florida and further into the Southeast. In response, Crane Engineering Company was founded, which was an impressive name for a tiny yet highly ambitious firm.
By the mid-1950’s the flathead Ford and early overhead-valve Oldsmobile and Cadillac V-8’s were replaced by the powerful, compact Chevrolet 265-283 V-8 engine family. It seemed that with the early small-block Chevys came a surge of growth for all forms of auto racing. Drag strips and oval tracks suddenly appeared, not only across Florida, but the nation, and the tiny backroom cam company grew as well.
In 1960, a Georgia Tech University engineering student and weekend drag racer, Pete Robinson, bought a Crane cam for his supercharged Buick powered 1940 Ford. After success on the street and at the drags, Robinson sold the ‘40 and bought a dragster chassis from the Dragmaster Chassis company, in California. Pete carefully assembled a stroker crankshaft,
supercharged, small-block Chevy, and installed a Crane roller cam. Robinson’s new car ran well on Atlanta area tracks and at a few NHRA Division 2 events. On a whim, he entered the “Southwind” dragster into
