No Replacement for Displacement (myth or fact)

In a perfectly controlled lab environment, the theory is sound, however, as I'm fond of saying...

"in theory, theory and practice are the same...in practice, they are different"

If you build a 340, and then replace only the short block with a 416 with comprable parts...I'm fairly certain the larger displacement incarnation will be more powereful.

Of coures this also then brings up the question...

Why do people idolize the 340, but shun the 360?


...and how about a 2 stroke cycle?

Not exactly more fuel efficient, but other effieiencies come into play, and power is nearly doubled vs a 4 stroke cycle.
