interesting that when the DA is below 800 I can't throw enough jet at my carb without it going into lean misfire. I considered the 4825 on my "small block" (439) fairly under carbed. Also running power valves. With 84 jets in Vegas I recorded afr on the left bank in the high 11's. At Famoso with 98 square I was at 14.6 with a DA of 800+. Sunday morning it was -800 when we set up, and around 100-200 when I made the pass which resulted in a lean misfire.



I used my power valves for fishing sinkers 40 years ago and haven’t used one since
