I like that cam for higher compression, and also its revised version (#24502476) with less intake duration for lower compression engines. https://paceperformance.com/i-62555...aft-gm-350-330-h-p-crate-engine-camshaft.html Both have lobes that are easy on the valve train, and quiet, too. Even GM roller cams aren't over the top aggressive like aftermarket cams. [/QUOTE] That's always the best answer to the question, "Which camshaft should I use?" If folks paid more attention to compression ratio, heads, low restriction exhaust, and optimal ignition timing, they would be amazed at how much power their engine would make with even a stock or entry level performance cam. This whole idea about simply installing a big cam and expecting more power is just nuts, especially in a 4WD pickup.
