Every 350 MPI I have seen has the same sort of intake. Maybe changed over the years, but for the most part they have a round air cleaner at the top and look nothing like the big block versions...
I'm looking at a boat with a 350 MPI... but it has an intake / fuel injection setup that looks like the 454 and 502 Mag. Anyone see one like that? What year(s) did they make them like that?
