Internal kinematics, huh? I read an interesting dyno test a while back whereby they tested identical builds, one with a shorter stroke and bigger bore and one with a longer stroke and smaller bore (they were BBC's IIRC) and the result was: No appreciable difference. They were attempting to debunk the theory that short stroke motors make more HP and long stroke motors make more torque. I think they succeeded.

Obviously there are potential valve shrouding issues and POTENTIALLY heavier reciprocating assy's with longer stroke motors, but for the sake of 360's vs. 340's, I'm gonna side with the 360. With IDENTICAL builds, any small advantage in geometry is going to be more than negated by the 360's 20 extra cubic inches.

.....as a previous poster said; if the 360 was introduced from the factory built identically to the earlier 340, people's opinions of 360's would be far different today.
