I also wonder about how the conventional wide-LSA wisdom for cams in the 230-240 degree range might change as you increase duration even for the longer stroke combos, I mean I run OF on a 112 in a 4.25 stroke combo, would I be better off on a 106 or 108 if I had a 250+ @ .050 cam?

It depends. Let start with. Street or race only? What kind of vacuum do you want at idle. The tighter the LSA for the same lobes the less the idle vacuum will be.
