Cool Vid!
I like the Detroit Diesel / Alpine Green for those 292's, gives em a unique look instead of trying to be a "too tall 250".
Those MV carbs are sometimes so lean, I cant even imagine one running with open headers but yours sounds pretty good. Needs more carburetor[s] though.
Glad you shut it off, Im the same way I will start one up with no water but only for 30 seconds or so. Then I make a stand with a radiator and test run em with water in there before they go in the car.
