    Mercuriser V8 5.7L marine block or not?

    4.3L to 4.3LX conversion, good idea for the price?

    Hi, first of all I don't know much about boats engine, I'm helping my parents finding their new boat! We're looking at 20' Cadorette Holiday 200 with a 4.3L. I know the 4.3LX has 4bbl, better HPs and better fuel economy. Is it worth it to buy a new carburetor and intake manifold to convert the...
