tooslow, luckily for me I make most of my own parts or I should say a lot of my own parts.
redneck, I think hitting 300rwhp will all come down to my intake. A guy on corral made 307rwhp with ported heads, cams and a sullivan intake(may have been an MMR boxed uppper I cant recall right off). He said his intake is just too much for the combo as he only turns it to 6500. Thats the major issue with a "mild" 5.4 DOHC, noone has an intake that works for us at the moment. Its either designed for too low(stock) of an RPM or too high(sullivan, MMR, etc..). From all I have read a ported cobra or widened cobra just doesnt flow enough and doesnt have enough meat to portmatch to the larger navi heads. I am drawing up a few diff designs Ill be trying in the near future to maybe remedy this and save everyone some money.
As for your fuel system, smart move. T'ing off like you did is what anyone looking to make serious power should do IMO. When I designed and made(from the routing, lines, custom rail, etc...) I did mine the same basic way as you. Some didnt do it this way and experienced a lean condition(In a supra's case, using one long rail it was the last injector #6 that was lacking). Kinda comparing apples to staples since you have a returnless system but still a good idea on either IMO.
