340 stroker

I’m running a 4” crank in my 440 small block. In my situation i could go with a lot more crank and get to the 470s but IMO at the 4.187 that I’m at now I get enough inches. Before this motor I was running a stock block with a 4.2”??? Stroke Crank Not sure but the crank was outrageous made 421 ci that motor was sleeved in 6 cylinders. The geometry was crappy it ate up the cylinders. If you can make the power with less stroke then why give your motor the extra unishment? Not sure if this is ir3333 reason but I completely understand that having all the stroke you can does play a part in wearing out the motor
