More modern 90° V6 engines avoid this problem. They use a split crank pin where the piston connects to the crankshaft. This makes an even 120° firing pattern. A 'split' crank pin is weaker than a straight one. Modern metallurgical techniques can produce a crankshaft that is strong enough to not break.
