it also has a front sump pan on it. im thinking this might have been a motor home engine, as it had what was left of a mouse in the valley pan. that leads me to believe it was sitting for a while, and the owners just decided to scrap the engine rather than try to fix it. the pistons are stamped 030, so it has been rebuilt at one time. im probably going to pull it apart, clean it, rering and rebearing it, and see what happens. anything else i need to look out for? btw it does have the forged crank in it. thanks guys!!
