Can someone please tell me the difference between the 7.4 horizon and 7.4 mpi Please. Is the horizon 380 hp?

I prefer Marriott brands myself.
OK so the 7.4 L came in three different versions 330 horse throttlebody injected which I have 340 hp multi port injected and 380 hp horizon all those hp ratings are at The crank though you do see at some point mercury started using horsepower ratings at the prop that's why you see a 310 hp version out there which is the 330 hp just had both of my motors rebuilt to factory spec and they made 330 hp on the nose on the Dyno I hope this helps
Thanks all. Just received an old survey and it has the motors at 340 h.p. ????:smt017
