the only problem i forsee with the zesty manifold is that he can't reuse the end of the stock plenum and that might make it pretty pricey. fabbing those up might be pretty involved since the bolt holes go through the surgetank. with a modified stock plenum, you can simply cut off the end section that has the mounting bolts and weld a tank onto that... which is probably why everyone's custom plenums are modified stock plenums.
