The formula for the area of a circle is pi times radius squared. The volume of the cylinder is area times stroke, and there are 8 cylinders.
So, 4.35/2=2.175*2.175*3.14159*3.48*8=413.79.
Engine manufacturers always round up, so 414.
By the way, it's not physically possible to bore a 350 that far, so this is an exercise in math not engine building.
Take your bore squared (multiplied by itself) times your stroke times 0.7854 times the number of cylinders in your engine to arrive at your cubic inches (cid). Here is that formula simplified: (bore) x (bore) x (stroke) x 0.7854 x (# of cylinders) = cubic inch displacement.
.7853982 x bore² x stroke x number of cylinders. this for cubic inches
A 4.060 bore with a 3.75 stroke is 388. A 4.060 bore with a 350 crankshaft is 360. yes the cubic inches of a Chevy small block with a 4.060 bore and a 3.75 stroke would have 388.4 cubic inches of desplacement however if you have a 4.060 bore and a 4.00 inch stroke you can have 414.3 cid but you have to use a 5.850in connecting rod for clearance of the counter weights
Bore x Stroke x Number of cylinders = cubic inches. Another contributor says: Wrong! Right answer is: Bore AREA x Stroke x Number of cylinders. That simply means that the piston or bore AREA multiplied by the piston's movement limit is the volume of each cylinder. Multiply that by the number of cylinders. For cubic inches capacity (or volume displacement) all units of measurement must be of course in inches.
Technically it's called a 360 since that's how many cubic inches it now displaces. 4.060 bore X 3.480 stroke = 360.421 cubic inches.
The compression ratio doesn't deal with the displacement, the bore and stroke do. If it's a modern engine it should say the size of the engine in liters. You can use this to convert the engine size to cubic inches. A 173ci engine is a 2.8L engine when converted.
350 cubic inch means, if you measure inside the 8 cylinders of a 350 eng., the area inside the cylinders would equal 350 cubic inches. a 350 engine bore is 4.00 inches and the stroke is 3.480 inches, this area equals 350 cu. in.
3.48 inches.
9.4247 cubic inches
If my math is correct , with a 3.7 inch bore and 4.02 inch stroke , it works out to ( 345.6 cubic inches ) I know that G.M. calls their 350 cubic inch a 5.7 liter
This is the formula. Area = .7854 x bore^2 A = .7854 x 30.25 (5.5^2) A= 23.75 sq.in Volume = Area x stroke 23.75 x 5.5 = 130.625 cubic inches. *This is just one piston. If engine was a nine cylinder then 130.625 x 9 = 1175.625*
a Ford 400 had a 4 inch bore and 4 inch stroke. Simplest math motor EVER!! Given 4" bore x 4" stroke x pi (3.14) x 8 cylinders = 402 cubic inches. Bore this thing out .060 and you get: 4.060 x 4 x 3.14 x 8 = 408 cubic inches.
