"Guys, I just bought a 1998 boat with a 454. The engine has a crack. (I knew that when I bought it!!) In trying to find a replacement block I get differing opinions on what will and will not work.
Is there a difference in marine and auto 454's? Aren't marine engines lower compression? If so, where do they get the lower compression? I've been told there are no differences in the block.. I've been told 1996 and newer will work, but anything older will not, I've been told any 454 with one piece rear main and hyd roller cam will work. What's the real truth?"
