Oh wow, 3-4 months? I only went to the Comp website because I actually wanted a Howards shelf grind, but the 2 I had my eye on were not in stock ANYWHERE I could see on various internet parts sites....Ventured to the comp site just to see if I could find my old lobes in their catalog from the cam I had, and saw the sale advertised. If they are the same at 3-4 months, it may be back to just trying to find something used, or getting the old crane grind that's in the motor reground, although neither is really 100% ideal for the build which kinda sucks if spending the money...I just find that the lead times are almost always longer then they typically say, so it makes me wary since 3-4 months is already a long time.
