If some 1 could calculate my port displacement or tell me how to figure it out it would help alot.

11.25" flare on both side
10.5" long
7.75" internal size

you could always fill it with packing peanuts, then put them in a known square box and measure for volume

well the volume of a cyclinder is pi r^2 x length so

piX7.75^2x10.5

but idk if that would be consider correct due to the flares

hope it helps a little bit

Pi*r^2*h
Volume of the flares are negligable.
Gives you ~.29cuft.

^ Wrong, as you need the radius squared, not the diameter squared.
