thanks for all the replies.. the motor has about 15 hours on it.. it was put in a fresh water boat for 15 hours then i took it out.. it has aries 13.5-1 pistons and it ran on alchohol .. everything in the motor has 15 hours since build but i was hesitant with the rods.. my plan is to get some different pistons and bring it down to about 10-1 compression and change the rods.. it has a crazy cam with a lift in the mid 700's and triple valve springs with roller rockers .. what do you guys think about my plan or any advice on what i am doing? thanks
