What is the displacement of a 350 motor bored .030" over? I brought my 89 350 TPI block to a machine shop and he said it would be a good idea to bore it .030" over. What would the displacment be?

Ok, thanks. |
No real intent to flame, but this is junior high math. Volume of a cylinder = area of the base times height. For an engine, the area of the base = bore, height = stroke. This is the volume displacement, as it's called. Area of circle = pi times radius squared, or pi x diameter / 4 (pi ~ 3.14159) For a 350, the standard bore is 4.000". Bored .030" over, it's 4.030. 4.030 squared divided by 4 = 4.060225. Times pi = 12.7556. The stroke of a 350 is 3.48", so above times that = 44.3894 cubic inches. That's the volume displacement of each cylinder, and there are 8 of them, so the total displacement is 355.11 cubic inches.

If I have a circle that has a 2" diameter. So the area should be radius square * pi. I'm coming up with PI. 1 square = 1 * pi = pi Now with your formula (pi x diameter /4) I'm coming up with 1.57 ??? Ron ------------------ '82 Trans Am '81 Camaro Z-28 '94 Vette LT1 Coupe |
