Need Replacement 454 block, question re: version
 

I just cracked a 454 out of a 89 force 235. Mechanical fuel pump. Two piece seal. How far back does this block go. It cannot be sleeved. Cracked almost to head bolts. Also, any ideas why it cracked? Piston in pieces, rod bent. I know water, but, from exhaust or head? 21 years old but well maintained. No salt water. Boat does (did) sixty empty. Any ideas for more efficiency and or power with realiability. I want to stay normaly asperiated. Also, four bolt vs. two bolt mains. Any help would be appreciated. First time rebuild for me. Can't believe this, broke in august!
