Ok, Scott, you seem to have a handle on the Hemi manifolds, which one do I have - as in, is it truly an original - with part # 2780544?




Are you asking if it's a reproduction or not? If so there are none being sold yet so yes, #2780544 would be an original Street hemi dual 4 intake.

If you have a good pic of the front area I could probably tell you what vintage it is.
