Mine is sitting on the side of the house, just removed the 250 due to a blown head gasket. Pulled the integrated head off, the exhaust manifold was cracked 2/3's of the way around just in front of the heat riser. Took a good look at the block deck and found a crack in the block about two inches long.
Pulled the block and layed it to the side, pulling a 350 from another truck to replace it. First part of the transformation.
In fact my truck is the exact same color as Mr79C10, don't have any pic's as of yet. I guess this is a great time to start.
