    Will this fit a 454 Chevy in a boat

    Asked by: Cleaver
    Depending on the boat setup it could. You would need to have dry exhaust for the o2 sensor to begin.

    Do you make a distributor for a 455 Olds?I see no mention of the engines you support. I have an Mallory electronic distributor now. Will it work with your EFI unit?

    Asked by: Olds 442
    No, this will not fit the 460 Ford engine. this EFI kit requires a dual sync distributor to work.

    Do you need an ignition box to go with distributor or does the distributor just plug into the sniper efi to control timing?

    Asked by: mikelh
    The EFI unit will control the distributor.
