    Blown BBC Timing

    Not knowing anything about the ignition timing of a blown bbc engine, where should we start? I do not have access to a dyno.

    X2, better safe than sorry, maybe a little more with alcohol. I run 34 with a sm/blk on alcohol. If you have access to a dyno, that's the best place to play with it.
