Re: 67 BB with AC RH water pump stud.
The stud doesn't show in the A.I.M. as being replaced with an assembly plant-installed stud, so it was part of the engine assembly as shipped, and was painted. My take, anyway. -
Re: 67 BB with AC RH water pump stud.
I studied this a little for my 67 big block and came to the following conclusion:
The stud was in the waterpump block assy prior to painting. This stud is used for bracketry on a 427 passenger car but not on a Corvette. The stud was covered with a shield during painting so as to not get paint on the threads..possibly a piece of tubing or something similiar.... That way when the stud was used on a passenger car with options the threads were not full of paint. I observed this on a 427 survivor at Stone Mountain in April... No paint on the threaded stud but there was paint on the hex bolt. I also observed a 67 427 Chevrolet with a bracket attached to that point at a recent AACA national meet. Thus the basis for my conclusion... Sooooooo yes the hex bolt was painted but the threads were not.Comment

Re: 67 BB with AC RH water pump stud.
Yes the stud was used for bracketry. The stud was used to mount smog pump brackets on '66 and '67 Corvettes as well as passenger cars. How do I know this. I own a '66 with K19. By the way it is a '66 427/390 with k19 and C60.
