This is a guy I follow on Youtube, does a lot of Mopar stock type builds and has a SuperFlow dyno. This is a '67 440 hp build they did for a GTX, they did break-in and initial pulls with a few non-stock parts, then afterwards the customer brought in stock carb, ignition, and exhaust manifolds to get a genuine test. Not sure if they've posted another video with the all stock test, interested in seeing it.
