    The po on my Jimmy said that the 305 was replaced with a 350. I replaced the alt. today and found this stamping # on the front pad K0330RHA. Any ideas? Thanks in advance, Bret.

    Edit: K0330PHA /forums/images/graemlins/waytogo.gif

    vortecs started in 96

    the two sites that i know of that list suffix stamping codes are
    www.73-87.com and click on the "chevys ID"
    www.nastyz28.com ans click on numbers decoding, then on sbc suffix
