Would like to get some help if possible. I have a 85 bayliner capri 1950 it has a 305 gm motor that the person i got it from did not winterize it and cracked the block. I have a gm 350 four bolt main that i plan on putting back in the boat. my question is what kind of cam should a motor that will be going in a boat have what should the rpm rang be at im thinking a cam that has a rpm rang starting around 2000 up to 5500 would be a good cam if antone has any opion i would like to hear thanks for all the help so far glad i found this site has been very helpful so far
