Hi guys, what motor mods can I do to get more out of my 1988 Volvo Penta 280, 5.7 to make that thing go (Heads, Cam, Intake, Carb, Super Charger, Nos etc....)

You could upgrade to vortec heads, you'd need to change the intake manifold as well. that would gain you 30 HP. I assume you already have a 4 barrel carb.
I don't know anything about Nos, supercharger, etc. May as well buy a different boat.
With that hull more HP will not translate to much more speed. It is not like a car where the rolling resistance is not a limiting factor your hull limits your max speed by the amount of drag you create with contact with the water. All you will accomplish is spending a lot of mony so that you can burn a lot more fuel.
Ayuh,... You've got your Cart ahead of your Horse,....
You should have been asking that question Before it was rebuilt,...
Unless you're planning to do it Again...
What type of vortec heads? (Cast, Steel, Aluminum) I curently have 1988 heads with pressed in studs.
Can I run Aluminum Heads? I have an heat exchanger running coolant.
Also, I have a set of 1963 camel hump 2 heads with 202-196 valves rebuilt sitting on my race motor never used with all of the goodies. I know I will have to change the springs.
With the stock cam can I change the rocker duration (it just give me more lift without changing the cam duration)? Or is that a no-no...
