Cylinder Head CCs and Compression
checked 88 cc chamber volume, and my compression is 10.1,
You know this because you measured
everything and did the math? For a 440 to be 10/1 requires a TOTAL chamber volume of (440/8)/(10-1)=6.111 cubic inches, which converts to;
6.111 X 16.387=100cc TOTAL. Dropping 10cc I get almost same as Kern Dog.
The cylinder pressure,and loading have to married just right, to stay out of detonation. The cam is a huge player in determining pressure; seconded by elevation and SCR; and handicapped by vehicle weigh,stall,gearing, and traction.
@Kern Dog
IDK about BBs,
But,
in my closed-chamber,tight-Quench,Eddie-headed 367,
I run a tic under 11/1 with an Ica of 66*, making a tic under 180psi,on 87E10, with Power-timing of 34*@3400rpm, in a streeter;detonation-free@900ft.
Jus saying
