I don't know if this is acurate or not but I have heard from a couple different engine builders that if your goal is the biggest number of tq you should run a cam around 236@.050 but they state (obviously)that this will vary some from one combo to the other.

For a bunch of examples of high specific TQ look at the last few engine masters competitions, very interesting stuff in there
