That's way cool, but I think he messed up on his calculation of displacement. How could a 1/6th scale of a 327ci motor displace only 1.10ci?

 

Area of the bore is 1.13sq inches, and stroke is 0.49 inches. So I get about 0.55ci displacement for each cylinder. Did he forget to multiply by 8 or something?

The bore of a 1964 327 is 4.001" with a 3.25" stroke.

 

So 1/6 scale would be a bore of .667" and a stroke of .542"

 

.25 * .667 squared * PI = .349 square inches * .542 *8 = 1.51 cubic inches

 

but he lists the bore as being 0.600" and the stroke as 0.487", so

.25 * .6 squared * PI = .283 square inches * .487 * 8 = 1.10 cubic inches.

 

Remember, PI r squared, or 1/4 PI d squared. The bore is diameter, not radius.

Divide the bore by 2 to get the radius.

 

And yes, way cool!
