The instructions say .003 to .004 per inch of cylinder diameter. Calculates out to .011” to .015”. What end gap should I use? Anyone used this combination?
Thanks, Jsaum |

I’ve looked and found several different call outs. The Haynes manual is calling out .0138 to .0216 for both the top and lower compression rings for a 2.0. This is a 1911 engine build with 96mm AA pistons and cylinders using Grant rings. If I go to the top call out in the Grant instructions at .016 I should be safe. I was hoping someone might have used the same combination and could give me the gap they used to confirm I have it right.
