Input Information

Description Input Example
Number of Cylinders 8
Bore (inches) 4.060
Stroke (inches) 3.48
Deck Height (inches) .010
Gasket Thickness (inches) .050
Gasket bore dia. (inches) 4.080
Chamber Volume (cc) 58
Dome Displacement (cc) 9

Notes: Dome Displacement is a positive number if the piston has a dome that exceeds the volume of any valve reliefs. A flat top piston with valve reliefs for example, has a VOLUME and doesn't displace anything. In that case, the value would be negative.
