Man I shouldn't say this but the title hooked me into thinking there was some kind of '36 car in this question, and there is. But the different engine, different headers, duals vs. single...

Well I'll just say I have nothing to add if an X or crossover would be of any benefit.

But just for discussion, would you prefer a power or sound or possibly economy benefit?

Edit to add a pic of a very nice custom rig for an off-topic V-8... Not sure it applies but I bet this one helps the HP and does JACK for the noise...
