But John,
They used heavier rods (thicker section/longer), standard bearing sizes, same
weight block structure. I'll give you lighter pistons, which makes sense about
reducing loads and inertia of reciprocating mass.
UNLESS you are talking about the design of a NEW engine, with a NEW block
design.
Then this is not the subject of this thread about mods to stock engines, and the
choices of
bore/stroke ratios depend upon a lot of application design requirements, etc.
