So that is where I’m at right now. According to the paper that came with the pistons, using their ring gap factor, my ring gap should be .03152. (3.94x.0080). Now the paper says a 4.000 bore which obviously mine is smaller so I’m thinking a .030 should do the trick. What do you think?
Also I put the ring in the bore to test out the feeler gauge. I got .018 is the gap right now for the #1 bore. .019 will not fit in the gap. So I’ll have to grind and test the gap to get it to .030
