Does bigger displacement mean more power?
Generally yes, but power depends on many factors: compression, airflow, fuel delivery, and tuning. A well-built smaller engine can outperform a larger one.
How do I find my engine's bore and stroke?
Check manufacturer specs, service manual, or measure directly. Bore requires a bore gauge; stroke can be measured with the crank at TDC/BDC.
What's the difference between CC and CI?
Just different units. 1 cubic inch = 16.387 cc. American cars use CI (302, 350, 454), imports use CC or liters.
Can I increase displacement?
Yes, via boring (larger pistons) or stroking (longer crankshaft). Both require machine work. Stroker kits are common upgrades.
