Ok we have talked about lengthening the forcing cone with Heavy loads. I had a 1187 that came in that we cut off to 26 and choked it then length the forcing cone. We test fire it a few times today in some fare weather.
One was 3-2-7's and it put 284.
One was what they said was a 3-2-7 but it looks like 6's to me. It was 220.
