When they were new back in the 60's, the street Hemi had low tension Dykes rings from the factory, as well forged pistons set up with a loose fit in the bore. That is a recipe for oil consumption, and Mopar stated as such.

A 426 Hemi with a modern set of rings will use no more oil that any similarly built forged piston, peformance engine.

My green 67 GTX, back when the engine was stock and pretty well worn out would go about 200-300 miles on a quart.

My blue 67 GTX convert that I drove about 5000 miles on the last 2 Drag Week event goes 1200 - 1500 miles on a quart.
