So my head should be fixed this week and of course my block is still completely fubar.
I found a 460 locally that was in his grandpa's barn.
He drained the oil, pulled the pan and the valve covers and said everything looked surprisingly good. Rotated the engine as well. Two bolt main. It is intake all the way down the the pan.
I am no expert, but would this be usable for a jet boat application? Teach me please! I am sure it isnt that easy to Frankenstein a motor back together. I am also sure since it has been sitting that might be a problem. But he was asking a dirt cheap price and it is right in town so it was worth the shot.
