It took all day to tear apart that engine. We knew the engine was ruined from not having a hood on it for who knows how long at the salvage. It had water in it. One cylinder wall is heavily pitted from water. The pistons are stamped 040. I pulled the main caps and it's 10 under. The crank is cast instead of forged. When I pulled a rod cap, I found the knock the salvage owner said it had. It's no big deal, I bought it for the extra accessories and the aluminum intake.
