What can we learn about Quench clearance
and the ratio of rod length to stroke
By looking at

Magnum 5.2 .... 3.31 .... 9.1 comp ratio
Magnum 5.9 .... 3.58 .... 8.9 ( really 8.7 or so)
Iron V10 8.0 .... 3.84 .... 8.4

All wth 6.123 connecting rods

Willem Weertman says in his book Chrysler Engines
that the 8 L Iron block truck V10 used the Magnum 5.9 pistons to keep costs down

As the rod/stroke ratio gets Higher
The piston "dwells" longer near top dead center
And allegedly the fuel burning completes faster because pressure stays higher

I wish Bob Lutz had ordered the engineers using the new computer programs
to build the first iron V10 with a 3.31 stroke and the flat top Magnum 5.2 pistons,
and maybe a tight quench 10.5 to 1 compression ratio requiring premium 92 AKI gasoline,
then increased the stroke every couple years to add cubic inches.
