If the cylinders were bored .10 inch over, calculate the new resulting engine displacement?

  Cubic Inches, Per Cylinder = Bore x Bore x Stroke x 0.7854

  Multiply that by the number of cylinders.

  Here’s how it looks for a Chevy 350:

  4 x 4 x 3.48 x 0.7854 = 43.73 cubic inches per cylinder

  43.73 x 8 = 349.84

  First, we need the number of cylinders, the year, make, model and engine size or this question cannot be answered.

  By the way, 10 thousand over will not change the displacement much. It will, however, increase combustion pressure, if your valve train is in good shape.

  Ha ha, what was the original displacement?

  What is the stroke length?

  How many cylinders?

  …on most engines, boring an additional .10 inches, the result will be a busted head because of thin cylinder walls!

  The formula for finding the area of any cylinder is pi = 3.14 x diameter squared x stroke x number of cylinders.

  100 thou is to much to rebore an automobile engine and you havent given details of original bore size—perhaps you mean 10 thou

  standard re-bore on most motors to get complete piston wall clean up is .030 (thirty thousandths)
