    I need a new motor, I would like to go with a 350-350hp but can we keep the SFI and computer or would we have to replace everything....
    or would it be best to go stock 250-290hp

    Thanks
    (don't know which way to turn)

    You can find a 350 horse- 350 to work with your SFI but you might have to ditch your computer or get it retuned so that it works properly and delivers the most powerfull ignition curve and to get the proper amount of fuel to your hopped-up crate motor.
