I know. I was saying "my bad" to actually taking him seriously and giving a real reply, but I'm glad you guys got benefit out of it!

i guess the best way i can explain it is that with a better rod:stroke ratio, the pistons have more "dwell" at the top of their travel which allows the charge to cool slightly before ignition, so you can run more timing and make more power. something like that, haha.
