Big Problems with New 408 +PICS

I didnt write that clearly enough I guess. I meant that if the rings were removed from that cylinder's piston, and placed back int he bore and the gaps checked now, the end gap should be .035 to .040. Because the extra .007-.008 of bore will cause the gaps to grow by a lot. I would think the assembler would have noted what the ring gaps were in that hole, and the others. If they set it at .018, it was probably too tight for the intended use. Depending on the ring manufacturer and piston type, I would probably go .019 on the top, and .022 on the 2nd on a 4.03 bore that was going to be raced. If I read right on the other site this was posted, you don't have a dial bore gage. You should if you want to properly measure this stuff.
