So, what’s the deal with the r3 blocks? Jegs lists a 9.025 deck 48 degree dry sump block for $2900. Says it will ship on the 23rd of this month. Is this not really available? Or is it just an undesirable configuration?

As for the ritter blocks... what ever became of the xr block that accepted the p7 heads/ cam?
A tall deck aliminum version of that would be absolutely fantastic to get your hands on.
