Hello all!
I am new here and looking to enhance the performance of my 2002 23ft Caravelle Interceptor. It has a 260 hp version 5.7 liter. Or as Volvo marks it 5.7 liter GL. I would like to change the heads if needed, cam intake combo to make 350 to 400 hp. I am unsure what heads are on the motor may be vortec. I understand building car hp a little better but realize boats are a little different. Also I have captains call and do I need to change exhaust manifold. Any help would help. I really need some guidence. Please dont assume I know a thing!!! Thanks for help
