a long-stroke/small-bore combination is simply less efficient than a short-stroke/big-bore combination on several counts


Huh.

And yet the highly successful Ford coyote 5.0 is 3.63 bore with a 3.65 stroke....... while the old school 5.0 is a 4.00 bore and a 3.00 stroke. work

You go for the 470....... I’ll take the 511.
41 extra cubes for zero extra dollars and zero extra effort is a win win in my book.
