70Mopes. Wuz happenin'. First, verify that its the original engine. If so, check if there's an HP stamping on the engine pad next to engine year & size - & then if there's any evidence of the original engine paint, that will tell you for sure.

In our discussions here this past year on 1969 & 1970 B/E body 383 4bbl's w/ AC and correct engine color, an original BCS records the engine's designated factory code. Do you have one? It's there on line 4, a 3 digit code. If you found a code, share it here and someone else can tell you what color it was intended to be.

All of Dodge & Plymouth's non-High Performance 383 & 440 4bbl's in 1970 were painted blue - while all HP 383 4bbl's were orange. Lastly, Carter carbs were only installed onto the non-HP 383's. At least, that's what I've been learning here.

There were factors or a matrix then that determined if a HP or non-HP engine was installed when A/C was ordered. What those were is still being researched. So let us know what you find out.

I would wait to hear more from owners of original 1969 RR's just like yours.
