First time post engine rebuild advice please

My dually would so smoke that car............

Sound comes with power, I have heard bad *** 340 cam cars, and weak sounding 340 cam cars. I have a 268/276 voodoo here, I would recommend it if you are going hyd lifters. It chops like the cam in your movie, and has another 1K or so over the powerband of the stock 340 cam, and seems to not have any less low end.
