where to buy small block to slant adapter?

Try advanced adapters. They make adapters for just about everything. Worth a shot

just tried em and no go on the adapter. I did send an email requesting that compo but after looking at some of the prices 400.00-500.00 for a piece of billet with out a crank adapter is a little steep.... especially for a slant adapter. I'll stick with looking for a used unit or try to talk Didiot over at slantsix.org to make a run if he get's enough requests.
