Why a blow through and not a fuelie? Understood the engine management will run more, but the manifolds are in the same price range, and the fuelie will give you better economy if it's going to be street driven, and more consistancy at the track, as well as more power, since you are better able to ensure the proper fuel is there for each cyclinder, rather than relying entirely on intake manifold runner design.
Working on a project of my own, and decided to go fuelie rather than blow through, as blow through presents more headaches than solutions to me, although I may be misinformed.
