cylinder pressure and dynamic compression with different camshafts`

L2316F40 deburred and polished top
66 cc chamber deburred
25 initial 35 total mechanical
run a good cooling system and proper AFR
Show your work for me if you can, because something's not adding up there.
Who did your math?
I get no where near the dynamic you say. I could run that high of timing too, but not under wot, and its not about afr...I even question 93 making the diff, polished piston tops or not, the chamber is where the trouble really lies...but hey..... I think your math is quite possibly jumbled. Because I'm coming up with your dynamic in the 7's and 155ish cranking.
But I won't call you a liar, I'm not there to see, check , or disprove it, so good job on whatever you got there!

I did go out and recheck mine yesterday during a break in the rain and with the carb pinned open have 190 cranking, yikes.
