I assumed you could see where the bunks mount and that would be good enough. The brush strokes are visible from about one foot away (eye from the trailer). Like I said before it all depends on how good you want it to turn out. I did mine like that because when it's on the trailer it's either in my back yard or the launch ramp so I didn't care too much about it.

The bunks looked just like that one. 

The engine's builder went through a lot of different reasons as to why something like this would happen to an engine. He's charging me $200 to tear it down and put it back together again. For $200 and my lack of knowledge it sound s like a deal to me. If it happens again... 

You didn't need to 2nd Day that $, no worries, they're just sitting in a box waiting for you...

The builder said it won't be a problem to match the waisted piston up, .030 bore, stock rod length, Sealed Power forged, can't find the part number 23__... I've got another smoked BBC that came with the boat, that one is a two bolt main, cast crank 454, missing one rod and two pistons. I'm not sure what I'm going to do with that engine yet. I was going to use it for a winter project but I think I'd rather work on this...

So cracked might have been an understatement.
