Well, Chris it's likely that it's just one of two shops in town that 
know Mopars - OK, maybe three. None of them have modern CNC equipment. 

While I advocate the procedure, it's the local execution that is 
lacking. IMO, the casting/location of the pick up boss plays a big part 
in the decision to do it by hand. A guy in the RPM club had his done by 
the BS and the pick up boss later cracked, sucked air, then trashed the 
engine. The BS no longer is willing to do this procedure, or if they do, 
they strongly advise against it. It's one of the reasons I chose to have 
my block sent out of town.

I had my entire block CNC'd machined by Chenoweth Racing in IL. They 
offset ream the original opening toward the rail of the block, then 
blend the passage. This leaves the crank side of the boss with plenty of 
meat.
