I have a chance to pick up a P5155072 block for my next hemi but can't find info on it. Is this block a standard height cam or raised? I know it's finish honed to 4.25 but it is siamesed and I would like to know if it was designed to go to 4.5 as that is what I want to build this time. Any help is appreciated.
And lastly, how is the machining on these (I'll have it bored anyway but I was more concerned about line hones of mains and cam and how true the decks are)? I would sooner have the older style MP block but I won't buy used and they are a bit hard to find new.
