What would happen if a guy put a X head on left side, and a 318 smog head on the right side, a custom ground cam that one bank had stock 318 specs, and the other bank had .470 lift/230 duration, left side header, right side 318 manifold... you get the picture.... lol little off topic but... :D

That kinda reminds me of Tom Hoover's 57 Plymouth with a 392 hemi. Yeah, same Tom Hoover who later became the "father of the 426 Hemi," among other things. Anyway, he designed a ram tube intake with longer tubes for one bank and shorter tubes for the other. More torque on one side, more hp on the other. Car was a national record holder in C Gas Automatic.

Edited to clarify he was the father of the 426 Hemi.
