    1991-7 pedal 200 efi

    Question,I was hoping if someone can tell me if on 1991 200-7 pedal efi are the cylinder ports and internal any better that a 200 FF block. I know the exhaust chest is restricted plans are to open that up,just trying to get a direction with this motor. I have read people saying it was a early Promax. Thank You for the Help.

    Yes the 1991 blocks are like the 225pm blocks. it used the skinny bottom guided rods. I bought a carb one new in 1991 for $7500 installed.
