JMHO. but your ring gap of .026 & .027 is not large enough for a 400ci to cause that much crankcase pressure.

Are you sure your rings are installed correctly? Did you stagger the gaps? Did you measure and file end gaps correctly? Is the cylinder wall to piston clearance correct?
However, you could try exhaust evacuation (may not work well with mufflers);

Have you done a compression check to see if you have a broken ring?Last edited by 36 sedan; 12-15-2020 at 07:29 AM. Reason: add last comment
