I tend to agree with the longer rod and the lighter
piston BUT on the street which this is I like the longer
piston for better stability... yes you can do it with
either rod but everyone so far has stated LIGHT pistons
which in MOST cases is shorter.. on the street and longevity
I prefer the longer piston IF its still in the bore..
with the shorter rod you move the pin height down
(pushing the piston up for more piston in the bore)..
JMO... I'm no pro engine builder
