I will look into verifing the LQ4 / LQ9 cam part number...as I said before I thought that they were the same.
Regarding the cam doctor, all I need is an LQ4 and I can take it to Chet Herberts's cams (30 mins from my house) and have him doc the specs. He has all the equip and does most my custom cam grinds.
As far as the cam coming out is concerened, it will clear without moving the radiator or discharging the A/C
I have heard that the small base circle was an issue but that longer pushrods didn't effect the geometry enough to be a concern.
