What would be the new size of your Plymouth 340 if were bored 060 over?

If a Plymouth 340 engine is bored 0.060 inches over, its new displacement can be calculated by increasing the bore size. The original bore of the 340 is 4.04 inches, so boring it 0.060 inches results in a new bore of 4.10 inches. The total displacement can be calculated using the formula for engine displacement, which is (bore² × stroke × π/4 × number of cylinders). For the 340, the new displacement would be approximately 350 cubic inches.
