I think they are the same engine. The 330 hp is rated at the crank and the 310 is rated at the propshaft.

You guys are confusing with the old carb version, I think He's talking about the two MPI versions...
7.4 MPI had 310 HP at the prop
The 7.4 MPI LX had 330 HP at the prop... I heard the ECU was different... I don't think there was mutch differences in the internals... Maybe the heads?
