Compression ratio.  That will put you around 6.5:1.  You'll need custom
jobbers to get a more respectable ratio.  That and I believe the con rods on
the 90q are not as strong as the turbo rods  but I'm not 100% sure on that.
Paul Tingaud was running an MC lower end 7A upper end in a 90q at Mt
Washington this year (with VERY low compression)... thing went like stink
though.
