Rare Dodge Dart GT? Which engine is this?

Thanks toolmanmike, so only the solid cams had the adjustable. I recall many years ago a friend of mine had a 67' Dart 273, four Barrel, that had a solid cam, but thought maybe all did.
Yes just the solid cam's had the adjustable rockers except for the 340 TA/AAR engines. Hydraulic cam/lifters require different pushrods with the adjustable rockers.
