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

The only 440's in 68 Darts were GSS's done by Mr. Norm... About 50 of them were made, I knew a guy that used to have one of those when I was younger...
