Inliners International Forums General Discussion Engines difference between 230 and 250

The two engines have different pistons (and as a result different compression ratios) and I believe they have different crankshafts (which account for the 20 cubic inch difference - 3.25 inch stroke for the 230 vs. 3.53 for the 250). Other than that I believe the engines are exactly the same.
