Calculating Cubic Inch Displacement & Compression Ratio
Calculate your Compression Ratio
Sample: 6cyl 208 Engine
with 3.685 bore, 3.250 stroke, .045 head gasket thickness, 3.700
head gasket diameter, .005 deck clearance, .222 ring land height, flat top
piston w/0cc valve relief, and 56 cc head volume should give you a CID of
207.9 with a static compression ratio of 9.75:1.
NOTE: For this calculator to
work - you must have Java Script enabled, Netscape 4 and IE 4 or greater should
be fine!
