C.R. = Compression Ratio
S.V. = Swept Volumer
C.B. = Cylinder Bore Diameter
C.V. = Cleavrance Volume
H.V. = Head Volume (Measured)
E.D.V. = Effective Dome Volume
D.V. = Deck Clearance; Below Deck = negative
                                      Above Deck = Positive
G.V. = Gasket Volume
G.I. = Gasket Inside Diameter
C.G.T. = Compressed Gasket Thickness

1 Liter = 61.02 cubic inches
1 Liter = 1000cc

C.R. = S.V. + C.V.
                 C.V.

S.V. = 3.1414 x C.B. x C.B. x Stroke
                                 4

C.V. = H.V - E.D.V. + D.V. + G.V.

E.D.V. = Dome Volume - Valve Relief Volume

D.V. = 3.1416 x C.B. x C.B. x Deck Clearance
                                           4

G.V. = 3.1416 x G.I. x G.I. x C.G.T.
                                  4

Cylinder Volume = 3.1416 x Bore x Bore x Stroke
                                                         4

Cubic Inches =
.7854 x number of cylinders x Stroke x Bore x Bore

Horsepower = Torque x RPM
