First 1967 383 installed in a Barracuda

Why is my post #13 a head scratcher? Pretty self explanatory. The 440 in the limited built 68 Dart was an RB motor as was the 440 in the '69 M codes
Sorry, I just hit the agree button. I was confused as to why you mentioned the 440's in the 69's because we were talking about when the 383's first cane out in the 67's.
