    Default 85 302 ring sizes

    Anybody know what size rings came in the 85 302 HO? Is it the metric size like the 87-93?

    I think they are more like the earlier models...except forged and not cast...basically a flat top with four valve reliefs. Rings should be 5/64", 5/64", and 3/16"...

    The manual trans, carbureted engines for sure used the metric low tension ruing pack. I own one and went out and grabbed a piston and micrometer, measured the ring thickness and came up with 1.5mm, 1.5mm, and 3mm.
