    The image doesn’t correspond to the text.

    Using the advanced method of guesstimating, let’s assume the radius of each of the silicone spheres to be at least 20 cm. Applying V=(4/3) x pi r^3 we get a volume of 33510 cc.

    You’d need a radius of 10 cm to get down to 4000 cc. This corresponds to 20 cm diameter, or rather, the length of a human hand

        Well when it comes to engine displacement, you’re just talking about cylinder crosscut area times piston movement (so not even the entirety of the cylinder volume, just how much air the pistons displace). That 4.0 inline 6 is a big ol’ lump, but are the cylinders really that big if you think about it? Much of it is the crankcase, head, the block around the cylinders themselves, etc.

        4 liters is just a bit more than a gallon
