    Default How much is a 502 worth?

    Found a local bbc used crate 502 with aluminum edlebrock heads other than that its stock. It came out of a old mans dually truck( supposedly has 36,000 miles ) and was totalled, engine didnt seem to be messed up. Will still fire, how much yall think its worth? The heads themself are pretty $$ i thought.. Any test i can run to make sure im not taking it in the rear?

    A leakdown test could be a little misleading depending on how the rings happen to be lined up in a particular cylinder.

    With what you have told us I would guess $500. That is if it runs good. Might be less if it does not.

    The heads alone would be worth at least twice that I would think. I'd give a grand for it if I needed it.

    After talking to a few local guys some have told me it has had some problems. I guess being in a truck thats totalled could do that..

    thanks for the help.

    A good running stock 502/502 with low hours is worth about 3000 to 3500. Aluminum heads and aluminum intake manifold. Just my opinion.
