I was going to say.. Ther's no way they sell that dyno'd, if it comes that way. No plugs, no wires, no distributor, no water pump or fuel pump... I dont think so. They send you a dyno sheet for an egnien built with your specs. It cant be dyno tuned, then all the parts removed. (Ok, I know dyno fuel is no always pumped, nor is it hard to get ignition/carbs on and off. But a water pump? No crank pulley? Smells wrong to me. And. I wouldnt put hypers in a 4" arm engine, even with "Mopar large beam rods". (prob stock..) My opinion, they do good work, but things dont smell right. You should be able to get a buyilder to build you a better engine for a little more cash. It's no real bargain looking at the parts list. Fucntional. But nothing crazy. Really, a 360 with that cam listed should make close to 400hp. Nevermind a 408.
