Small block 6 pack manifolds are going extinct, I have talked to Edelbrock and they say they don't make them. Mopar Performance makes them? I said you don't make the B, RB, Hemi 6pack that say Edelbrock on them? He said Ahh, it's a privet label and I can't talk about it call Mopar Performance. Talking to MP is like talking to a 3 year old so I just hung up. I have been looking for a manifold for over a year for my friend, we have a carb set up and a air cleaner but no manifold. I think if enough people call MP and tell them to make manifolds it might work.
