It looks like the cam might be too big lowering your compression how does it feel at higher rpms does it pull strong? Also is your trans shifting too quick and not down shifting into lower gears?
He don’t know anything about the cam but I as well suspected this. The previous owner could have slid something in. His cylinder psi report (something 99% here don’t know or do) is pretty low but also pretty equal across the board.
I’m thinking this is a dead stock engine with bolt on parts and “The wrong Cam” installed or a super tired engine evenly across the board. That you don’t see everyday.
