banginAltima Posted April 30, 2008 Report Posted April 30, 2008 (edited) The port AREA of an 8 inch port is 50.27 square inches. (radiusxradiusx3.1416) = area The port VOLUME is (4x4x3.1416x18)=904.78 square inch ((radiusxradius)x3.1416xlength) = volume then divided by 1728 = cubic feet displacement 904.78/1728=.5236 cubic feet displacement.
