Sleeper,
thanks for you input. all the info helps. I had thought about those options when i built the boat. More CR and aluminum heads. I stayed away from aluminum heads actually for the reason I run in brackish water. Some guys say it doesn't make a difference and others say it does when it comes to corrosion. The CR I kept down because in the event that good gas was not
available on the water it would not matter so much. The current cam is a lanati flat tappet(245/255@50 615/622) which actually performs well in my current set up. Not the best grind for a turbo though. Lobe sep is only 110
and turbos typically like around 115-116.
