78 Aspen R/T 360 engine color?

I have a 78 Aspen R/T with a 360. Everything on the numbers engine block appears to have been black. Valve covers are black with an E58 sticker. All the literature I see says it should be blue.

I have seen some pictures of another R/T with a blue engine.

Anybody have an original painted engine car to provide some insight?

Thanks

Rob
