Well after replacing oil pump, I checked oil pressure and temperature and everything come out pretty good. So, I always take a final compression reading when i get done running any engine i just put it together. I commence to remove the plugs and check the burn pattern on the plugs and install the compression gauge and everything looked good until i got to the number 6, 7, 8 and the compression was low, I was like what the hell is going on, long story short I remove the heads to check what the hell happen and found some pretty nasty looking gouges in the 6, 7, 8 cylinders only all the other cylinders looked perfect beautiful. I don't know what the hell happen. Tomorrow I will remove the pan and pull the 6, 7, 8 pistons out and check what caused these gouges.
dk I have spiral locks on it and it has the 347 slugs in it i think maybe the oil ring reinforcement ring man I just dont know.
If there's gouges in the walls adjacent to the pins, you lost a few pin keepers. I had the same thing happen on a 427.
