340 Vs 360

if you give the 360 all the 340 attributes...better heads, higher compression etc. then you
have to give the 340 a 3.58 stroke, lighter pistons etc.
You 360 guys all want to use the good 340 parts but keep the larger displacement advantage.
if you match each with parts that are useable and shared the 340 will have smaller bearings and
a bigger bore.
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.
