# How many cubic inches is a 302 bored out 60 over?

The displacement of a 302ci Ford V8 bored 60-over is 310.71ci

To calculate cylinder volume you should know the bore and stroke sized of an engine. Say a 350ci Chevy V8 bored 60-over:

Normal bore of a 350 is 4" in diameter, so 60-over would measure 4.060" diameter bore. Stroke of a 350 is 3.48".

Equation for measuring internal displacement of an engine is: Bore Radius^2 * 3.14 (Pi) * Stroke * # of cylinders = Internal Displacement

So using that formula, we would divide of the bore diameter in half to get the radius. Radius is 2.03". Then calculate 2.03 to the 2nd power (2.03*2.03) is 4.1209". Now multiply 4.1209" by Pi which is 3.14. That equals 12.939626". This represents the 2-dimensional surface area of the bore. Now multiply that by the length of the cylinder stroke, which on this engine is 3.48". That equals 45.02989848 cubic inches (cylinder volume). You can round off the numbers to make it more simple, that's fine. Now 45.02989848 is the volume of a single cylinder of that engine. We know the 350ci has 8 cylinders, so we would now multiply by 8 to get the final calculation. The answer is 360.24 cubic inches.

I hope this explanation helps a little.

### What is a Chevy 350 engine bored 030 over called?

A 350 starts out with a 4.000" bore and a 3.48" crankshaft stroke which really only gives you 349.8 cubic inches. (Chevy rounded it up to 350) Your engine which has the same stroke of 3.48 but now is bored .030" over (making the cylinder bored size now 4.030) total size of 355.1 cubic inches or just a 355.

### How many cubic inches is a 396 bored out 60 over?

Ok. So the formula would be pi are squared times stroke times number of cylinders. The 396 bore was 4.096 inches, plus .060 inches would be 4.156 inches diameter. Radius would be 2.078 inches (one half the diameter). Radius squared would be 4.318 inches (radius times radius). Times pi (3.14159), that's 13.56 square inches. Times the stroke (3.76 inches) that's 51 cubic inches. Times 8 cylinders, that's 408.05 cubic inches.
