    Chevy Camshaft Identification


    Reaching out to members in the know regarding a camshaft I have in the GM tube. I bought this in the early 90's from a guy at work who told me it is a SBC 350 HP Hi-Perf camshaft.
    The GM tube has the ID number as 3863151 which correlates to a L79 Cam however the stamping at the end is 920883. The 4 digit ID on the camshaft core is 1529, which if correct I believe is for a 327 engine. The HI-PO color coded stripes on the camshaft end are green, orange and red.
    I thought this was a NOS L79 camshaft but the 920883 stamping at the end has me doubting that. Does anyone have an idea what this cam could be?

    Cam ID. Unknown part number


    I need help finding specs on a camshaft.
    SBC with the numbers :
    162F05 #06523
    Looks like a roller with about.500 lift.

    Hey Jim:

    Welcome to CHR. My information shows your 3863151 to be as follows:

    Hydraulic Flat Tappet
    Duration at .050 is: 221/221
    Lift: 447"/.447"
    Compression Ratio(as originally installed): 11.0:1
    Lobe Seperation:114
    Used in: 327/350HP L-79

    So it would appear to be a NOS L-79 cam. The numbers on the front don't line up with anything (at least not that I've found). The key numbers are located in the center of the cam between the lobes.
