Cam Lobe Guide Custom-Profile Cams Although the Crane Cams catalog includes an extensive variety of camshafts, unique applications do occur that may require a camshaft selection not found in our standard listings. This is not an unusual happening at Crane, where customground cams are produced daily. We maintain the largest lobe profile library of any performance cam grinder, an accumulation that began with our founding in 1953. We cover the entire spectrum of internal combustion engine applications, ranging from stationary power plants to Top Fuel dragsters. Prototype work is performed for a variety of clients, from the giant Original Equipment manufacturers to the individual engine builder/racer. Custom production runs are also commonplace for an equally diverse range of customers. Proprietary work is also a function of our diversity throughout the OEM and performance markets. It is always recommended that our staff of Performance Consultants be contacted (386/258-6174) as the first step in the initiation of a special camshaft order. Their combined decades of experience in all forms of camshaft applications can easily save the customer time (and money) when refining their particular combination. Following are some basic explanations and rules to follow when considering a custom-ground camshaft. Our hydraulic and mechanical profiles are designed for a particular finished lobe size. Applying a lobe design to an engine having a smaller base circle diameter than the lobe is intended for, will probably cause the minimum radius of curvature (which usually occurs at, or near, the maximum lift point) to decrease to an unacceptable level. This will cause premature lobe and lifter failure. Consideration is also given as to the type of valve train. Engines having an overhead valve style valve train (camlifters-pushrod-rocker arm-valve), can not utilize as much positive acceleration at the follower as those engines having direct-actuation valve trains (cam-follower-valve), due to the comparative stiffness of each style. Although the minimum tappet diameter and basic specifications may appear quite similar, there are great lobe design differences, mandating that these types not be interchanged. Hydraulic and mechanical profiles also have design differences, primarily in the clearance ramps. Without going into great detail, you should not use hydraulic lifters on a mechanical lifter cam, nor should you use mechanical lifters on a hydraulic lifter cam.
point going off of the edge of the tappet, usually causing immediate lobe and lifter wear and failure. A larger tappet can be used without this wear potential, however you may be sacrificing tappet velocity (which usually increases performance) if other profiles are available for larger tappets. Some common values for tappet diameter are: .842”
SB & BB Chevy, Pontiac and Buick V8
.875”
SB & BB Ford V8
.904”
Chrysler and AMC V8.

Crane Cams, Incorporated, offers a broad scope of services and capabilities from a single source - a unique and extremely advantageous feature. This multi-faceted service can provide a complete package of engine cam development and manufacturing, from design through sample cams for developmental evaluation at an amazingly low total cost. The “as measured” cam profile analysis services are the most accurate measurement and analysis data currently available in the industry. A precision measurement facility is located in the Crane facility and is used in many phases of Crane’s production and development work, as well as by various other engine and cam manufacturers. Sharing equal importance with the physical measurements are the computer analysis techniques employed in processing the “as measured” data. This process permits a broad and accurate analysis of the data with corrections to systematic and random errors, which occur in all measurement procedures. The resulting computer printout is an exceedingly accurate lift data (to the nearest 10 millionths of an inch) of the actual measured profile. This data can then be immediately compared to the design data. One outstanding feature of the cam profile analysis program allows one-degree (or 2-1/2 degree) design data to be read into the computer, which will immediately return printoutcutting data in one-half degree increments. This unique feature permits a model cam to be generated on one-half degree increments of maximum accuracy, even though the original design was tabulated in one-degree increments. Only the latest equipment is incorporated into the extensive cam development facilities at Crane Cams, Incorporated. Equipment is only as good as the people that use it, however, and Crane personnel have been one of the main keys to the firm’s successful rise to the “Number One” rating in the high performance cam industry. Top management at Crane fully appreciates the importance of care, accuracy, speed and competence, and reflects this concern in its total involvement in all cam facets, from design through volume production.
Inspection:
Tooling
1. Profile Check to verify lift and timing against furnished specifications. Time required: 2 to 3 working days.
From design data, the first step in cam profile production is the generation of the master cam lobe. At Crane, this is the most critical and precision step in cam profile manufacturing, since every step from this point forward can result in possible accumulative errors and deviations from the desired profile unless extreme detail and attention is afforded the project.

Cam Lobe Guide The grinder utilizes a General Electric Mark Century positioning control unit which positions the two axes of the worktable and a third vertical axis in the head. The Mark Century unit has a basic resolution of one millionth of an inch, with a complete system resolution of 10 millionths of an inch, and a grinding accuracy and repeatability of plus or minus 15 millionths. Manufacturing Crane utilizes Van Norman and Norton Automatic cam grinders for production cam grinding. If production volume run cams are desired, Crane offers the highest quality at competitive prices, backed up by the fastest delivery possible.
A. 1.786” nominal journal diameter (Buick V-6 and V-8, or special small base circle diameter. Chevrolet 262-400 V-8 requiring connecting rod to cam clearance in long stroke applications.) B. 1.868” nominal journal diameter (Chevrolet 262-400 and 348-409 V-8 and Pontiac 265-455 V-8) C. 1.948” to 1.968” or 50 mm journal diameter (Chevrolet 262-400 V-8 LRB, Chevrolet 396-454 V-8, Plymouth-Dodge 273-360, 350-440, & Hemi V-8’s) D. 2.036” nominal journal diameter (Ford 221-302 and 351C400 V-8’s), AMC E. 2.125” nominal journal diameter (Ford 429-460 and other engines)
Inspection Crane’s production run inspection procedures, designed to check production cams for accuracy, plus establishing performance parameters of a given camshaft of profile, is a very useful and rapid measuring device (Adcole 911) with resolution to .0001 inch and one-quarter of one degree.
F. 55 mm or 2.165” nominal journal diameter (Chevrolet LS1 V-8, Chevrolet Vortec V-8, Ford LRB, and other engines)
A custom-built dynamic inspection machine is utilized in many critical inspection areas to rapidly indicate acceleration, velocity, displacement and jerk of a model, or sample cam, profile. Relative smoothness can be instantly reviewed for comparison, as well as lobe-to lobe variations in profiles. The viewed trace on the oscilloscope truly gives a “finger-print” of the cam profile almost instantly, and with a minimum of set-up. Conclusions can be quickly established relating to dynamic problems due to design or manufacture. This machine is also utilized to select optimum lobes, average lobes, or worst lobes, for further inspection and analysis, or for copying profiles on developmental or test cams.
Some lobe designs have had masters generated for more than one size category. These have been indicated where applicable. When a roller lobe designed for one journal size is applied to an engine having a different nominal journal size, a duration change will occur. For example, an “A” lobe ground on a “C” engine camshaft will realize a four-degree increase at 0.050” cam lift. There is usually a two-degree change between design size series. Caution must be used when selecting a larger sized lobe for a smaller lobe application. If a “D” lobe were used on an “A” application, not only would a duration loss of eight degrees take place, but also a negative radius of curvature (inverted flank) may try to occur in the grinding process, resulting in a finished lobe shape that is not representative of the actual design shape. This may result in unstable valve train, possibly causing component failure. Lobes that are intended to have this inverted flank (Crane’s IR series) were carefully designed and manufactured using a special process to prevent this condition. Even so, IR camshafts are not normally advised for high RPM applications.
Also located at the Crane facility in Daytona Beach, Florida, is the physical measurement equipment. Another customdesigned installation, this machine performs precise measurement of “as made” cam profiles, conducts mathematical analysis to correct for systematic and random errors, and provides velocity and acceleration data. Features include a basic resolution of .000010 inch and two arc seconds. An extremely high accuracy of 20 millionths of an inch (mean standard deviation) is maintained through the operating system employed and close temperature control of the measurement room. Ground and lapped carbide utilized as cam followers, maintain high precision and accuracy.
G. 60 mm or 2.362” nominal journal diameter (Large cubic inch race only engines)
Our Adcole gage is considered to be the standard of the industry for camshaft design verification and production. (This is the measuring equipment virtually demanded by the Original Equipment manufacturers for quality control purposes.) Measurements are precise to within 1/10 micron (0.0001mm) and 0.001 degrees. Computer-aided control combines extreme accuracy with speed, and provides for complete plot traces of deviations from the programmed standards. Important: Lobe Design Size When Choosing a Roller Grind Our roller profiles are designed for a particular finished lobe size, as determined by engine types or base circle radius requirements. We have provided a column indicating the Lobe Design Size for each of the listed profiles. Coding is as follows:
