    REMARKS:







    Crane Cams continuously improves and upgrades its cam designs. In some cases this may mean that two Crane Cams with the same part number may actually be different grinds. You must check the GRIND NUMBER stamped on the front of the camshaft and check it against the Grind Number near the top of the Spec Card. For more information on the finest available camshafts, valve train components, and automotive ignition products, visit your local Crane dealer or call the Crane Cams tech line at (904) 258-6174 or FAX (904) 258-6167.

    Sounds like a good cam. I think that cam has good power in the low to mid rpm's

    Well, look at the advertised rpm range 2500-5500. Thats all mid and high range power and should probably be used with a 2500 stall converter. Really in a truck application 272 duration is plenty than you start getting out of the low end range.

    Thats a pretty good sized cam for a truck. You would want a little bit of a stall for its full potential.

    I can't seem to find where it says what the LSA (lobe separation angle) is. That is a huge factor in predicting a cams ability.
