Eurospec's stroker kit pricing

Someone asked about rod ratios before.  I've been poking around gathering i=
nformation and
found a website that calculates rod ratios using the broke and rod length.

It doesn't use weight and doesn't give inertial loads.  There are some sugg=
estions given as
to optimal rod ratios, and the ones that calculate out from the Eurospec 2.=
6 liter stroker kit
are outside those suggestions.  It comes out to be 1.507829109947644 (I did=
n't round),
and the range suggested is between 1.65 and 2.00.  This is using 5.6692 inc=
hes rod length,
converted from 144mm, and 95.5mm stroke.

But people still say it works.

Also I was reading in the q-list archives, and saw that Scott's (scottycboy=
) stroker motor was
a turbo.  I didn't realize that before.
