Not mine. These are the set of ProMax heads I checked out and wrote a post on years ago. I think I originally posted it on Moparts but have shared it here a couple of times. I probably should have bought the 340 short block or whole engine six months ago but it would have still been sitting here. Lol
I think the family that runs the Steele, AL DragStrip owns the Promaxx company. They are good people. I've not personally ran any of their products. But from what I've seen they are a good value.
