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.
