Relocate Master Cylinder?

Sorry but my eyes are blurry from searching the archives to no avail. I will need to relocate the master cylinder on my 66 Dart to make room for the 392 hemi valve covers.

Is this 392 the original 57-58 392 or the new version? If the 57-58 version, would sure like to see some pictures of that monster installed in an early A Body
