    O.k I'll bite. It's just a sbc ,I think. Assuming you can adjust it, and the timing isn't computer controlled. 32* to 36*(total timing) should be a good starting point. Maybe someone else will have more to add.

    Question My Guess

    The boat in your avatar would probably have a BBC. Same answer though.
    There must be a tune-up tech at your Chevy dealership that you could share your motor specs with. Al

    The 377 Scorpion is a computer controlled EFI. You can't just time it!!
    It must be put is base timing mode using a merc scan tool, then set the timing at IDLE, then put back in normal mode.
    I dont remember the timing spec at this moment. I'll look it up but I think it is 8 or 10 btdc at idle in base timing mode.
    If you have a Certified merc place do it they will have the specs in the dealer manual.
