I have a 350 chevy in my searay, it has a cracked block in it, I was thinking about buying a rebulit auto motor to put in it, I know the freeze plugs need to be brass and it uses a marine head gasket, but is there any other diff. that I should be aware of?? I would still be useing the standard marine applacations, such as carp, starter and altn. I would be just useing the auto long block
