Who are "360 guys"?
Your logic is flawed. The comparison is between a 340 and a 360. Stock for stock, yeah a 340 probably will win but who here cares? Answer nobody.
Now, given two generic engines, otherwise similarly built, similar quality parts, machining etc, the one with the longer stroke will win 99% of the time.
You might even say I'm a "big stroke" guy. I'll let the "little stroke" guys worry about little stuff.
