23' Performance 5.0 vs 5.7 Mercruiser

[FishStretcher]

So I have some of the parts. I have a bravo 3 and 300 MAG MPI. I just need to burn the valves out of it at WOT so I can justify those aluminum vortec heads... Although I am not sure there is a lot more power with those heads. Although with good valves and seats, maybe you can run harder at cruise.

With the knock sensor, I can try higher toluene content race gas and see what a bit more power will get me. If I have the prop pitch to use it.
