FWIW using an extreme 1.5:1 vs 3:1 , this video is very well done

What is interesting is how a short rod 'dwells' lest (relative to the same stroke) at TDC but more at BDC which with a long stroke partially explains why longer durations and earlier ICLs (vs a smaller cam in later with the same exhaust closing event) can be beneficial when you have a really good (or large) intake port. It also helps explain why under ported motors (like a 906 headed 440 or a 455 olds) benefit from a longer rod because the piston squeezes a bit longer at higher RPM/Piston speed.That helps the motor "hold on" near peak torque a bit longer on the way to the HP peak.
