Stan, I happen to think your software is the best thing since the invention
of the internal combustion engine. If you would like to play along using your
program we could answer some of the questions sounding flat top vs. dish
vs. reverse dome pistons.
In the picture below on the left is a typical heart shaped combustion
chamber. Using the flat top or reverse dome we would use all of the available
squish area (let's say 35%). Replacing it with a dish piston drastically
changes the picture. One distinct difference being the squish to bore ratio
is now lower (let's say 25%).
If you would calculate MSV for both.
Bore 4.030"
Stroke 3.48"
RPM 8500
