Looking for some idea to increase my engine from 330 hp to 400hp.
I mostly wakeboard on my 2550sx chaparral boat
I have mpi hirel fuel injection.
I have been looking at aluminum heads to help reduced the weight which is a slight issue. Question Oval or rectangle ports? I have both intake manifolds.
I like to put roller rockers and mild cam.
I have stock headers atm but plan to upgrade to lightning exhuast system which will give me more HP and reduce the weight by 70LBs
