Can I use a newer 5.8 in my old boat?

[revkev5064]

I have a 1977 Cobalt with a 235 Ford 351W. I need to put a new motor in it and know the newer Ford blocks have a one piece rear main seal and roller rockers. Can I swap the newer engine in? Will I have cam shaft issues? Can I use my intake and marine carb? Anything else I should be aware of? Thank you.
