There's a few options. The easiest is probably out of the question and that's ditch the lightning intake and blower. After that... you should be able to use your stock injector harness and injector rail. you'll have to widen the crossover hose but I can't see it being much tougher than that. I'd probably go the diagram and solder route but I'm twitchy that way. Your computer should probably be able to handle the motor with just a proper tune but I totally don't know specifically exactly how to do that... I'd just look at it, make sense of it and solder my way to happiness.

Stock 5.4 2v pistons are exactly the same as standard 4.6L 2v slugs. what looks to be a -4.5cc dish. To get 11:1 (not blower friendly on pump gas) you'd need PI heads with flat top pistons (roughly... many factors will affect that). Mine's getting 4.5cc dished pistons. Static compression should tick in at 10.25:1 or thereabouts with my specific combo.

exactly. what are they going to say when a stock 5.4 2v with no real mods smokes them... imagine what happens when you mod the piss out of it.
There's a saying, "There's no substitute for cubic inches." It's 100% right.
