    Opti 2.5L Block vs. carb/efi 2.5L 200 Block

    saw both of these block side by side and the porting looks very close . . . anyone know if there is much of a difference? Can a 2.5L opti block be built up as a carb motor?

    I am going to be building a 2.5 225xs block into a carbed motor here shortly hopefully it will work the porting is alittle different but it is a hipo opti and i was comparing it to a 260 block so we will see once i get into it and start measureing things and see if i need to mod anything inside.
