    I am looking for a spare 575 to get rebuilt and have ready. I thought I read that the 500efi and the 575 are the same long block. Is this right? And if so does that mean my Top end off of the existing motors will bolt right up?

    Thanks for any help.

    the 575's have 7.5:1 compression and hyd flat tappet cams

    500 EFI's have 8.75:1 compression and hyd roller cams.

    rest of the stuff should be the same.

    The 575SCI long block is the same as the Merc 600SC. They share the same cams, pistons, heads.
