[Roadsters] long rod (r16) stroker

[jeremy mayne]

I also believe the R16 rods are lighter than the U20 (I remember weighing them
when I was building my stroker, but I don't remember the weights).  They have
a more slender beam than the U20s.  This was part of my motivation for
lightening the U20 rods by about 30 grams each.  In an attempt to get a good
CR with the forklift dished pistons, I actually considered using the longer
R16 rods and having the tops of the pistons machined down rather than decking
the block.  It wouldn't work though, because by the time the pistons were
machined enough for clearance, the top ring would have been too close to the
top of the piston.  Maybe it could be done with custom pistons.
