Shovelhead A place to talk about Shovelheads. Thread Tools. Hi guys, Bought my FXS a year ago. The ride has lot's of modifications, but no specs. From the beginning the Shovel 'stutters' in the midrange. The rear cylinder doesn't beats a good rithm. The front cylinder beats well. At high speed no stuttering. Changing the mechanical ignition for a Crane HI-4 single fire ignition doensn't solved the stuttering. Both cylinders have good compression. The CV carb seems te work fine. Last weekend checked the camshaft.

Print Thread. I've got an old camshaft of which I'm trying to the specifications to. From what I've read, it seems to be a Crane Cam Core with a Chet Herbert grind but in searching there were two cams with two different specs that used the number so I'm trying to verify the cam information. Please, can someone help me in finding the original cam specs. Also, this cam is specifically for a Big Block Mopar Wedge engine 3 bolt. The number on the rear of the camshaft is: I believe this is the part number 8A2A I believe this is the heat treat batch number The number on the front of the camshaft is: CD then is listed again by itself.

Crane is a popular aftermarket producer of engine camshafts, which are used to actuate valves in engines. Camshafts vary based on the design and placement of lobes on the shaft, thus properly identifying a camshaft is critical to assure compatibility with your engine. Examine both ends of the camshaft. The end of the camshaft will be embossed with a two-digit engine prefix code, a grind number, and the series name of the camshaft. These three pieces of information will allow a consumer to identify the specifics of a given camshaft. Some Crane camshafts may have information on both ends of the camshaft. Using the information on the camshaft, look up the information in the Crane Cam Catalog. The catalog will list Crane cams by the series, prefix and grind. With this information you will be able to find the lift and duration parameters of the camshaft.

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.
