For you forced induction guys...

What was the ring gap you went with? I have a bore of 3.642, so I was thinking along the lines of .018 for the top, and .022 for the 2nd...

For anyone who cares to follow along the build, see:

i think i went 20 22 on a stock bore, because of plans for nitrous as well. might have been 18 20 though i forget.

Getting further. Never realized putting in those spirolox would make my fingertips hurt... Went with .018 for the top ring, .022 for the second ring, and used an old piston as a ring square...
