I have a 97 7.4LX MPI rated at 330 at the prop, 350 at the crank. That engine was discontinued in 97. It has the Merc injection, not the GM like the 310 has.

When I was doing a swap from a old school motor to a new school motor I was told they were exactly the same just a different way of measureing the power. The 330hp motor is the same power as the 300hp gen 6 motor.

does the 7.4mpi have a mild cam in it? there has to be something that is holding it back. 310 isnt bad hp but i would think it shouldbe pretty easy to get it up to 360 hp

My understanding is that the 7.4 MPI GM intake system leaves HP on the table and the cam is mild. Many people have modified base 7.4's (with carb. set-ups) to 400HP+.
