I measured 130cc, down 1/2" in the bore measured from the highest point (???) on the piston (quench block).
The actual volume of my 4.35"x 0.5" is 121.77cc
So I am coming up with an effective dish of 8.23cc
Am I on track here?
So if I plug those numbers into a compression ratio calculator I am getting 10.5:1, which I would consider fairly ideal for my setup at my altitude with 76 degrees overlap on the cam.
