Thanks man. At this point I'm only here to help others. My project is about done. Gotta give something back to the forums though... they helped me finish my dream.

If this thing puts out decent power i will probably be doing the swap after long tubes are available cant do it before as my supercharger will be suffocated.
Intercooled vortech stock block long tubes ceramic coated high flow catted h pipe dynomax mufflers (hey i like em:P) Custom Cai lightning maf installed by davenport racing
dyno'd at 418 rwhp 408tq
Before Headers and high flowing h pipe install and sc i dyno'd something like 230 rwhp
No boost guage but i believe its pullied the factory h/o kit 9-10 pounds:P
Something worked really well in the combo they said its far more then they have experianced in the past with other installs.
Basically im pondering a forged 5.0 aluminum stroker or the 5.4 forged if the intake and headers work well....I want to run 14 psi and possibly methanol injection

Longtubes, the new intake and a well done set of heads fed by 14lbs should be netting you pretty darn close to 500rwhp. make sure you take the need of fuel system into account on your budget.

I live in canada so gas is a big issue at 110 a litre:P will the 5.4 be much worse on gas?
I go to the track usually 1s a week in season so weight is an issue too.
Will a 5.4 4v stuff in? No intake options though right?
Will ported 2v heads flow enough under boost? they seem to now but i have not turned up the wick yet either:P

Engine combos are easy... only a few components affect matters greatly, other things that you'd think do dramatic things don't. The most important bits are, heads, cams, exhaust. The intake is important but not nearly as vital for the final output as those 3.
In order:
1. the 5.4 is a SUPER stroker but it's better designed to have the long stroke than a 3.7" stroke 4.6.
2. Fuel mileage in normal driving is no worse than the 4.6 in my experience. When you get your foot in it, things get substantially nastier than the 4.6 but , remember fuel burn is a function of HP generated so if your foot isn't in it deep it's no thirstier than a 4.6. I average 1-2mpg difference but sometimes it's better by that much and sometimes worse by that much.
3. total weight gain should be in the 80lb range. The gain in power and torque is more than worth it NA. Supercharged is like OMFG! that's fast.
4. 5.4 stuffs right in. You'll have very few challenges of any substance during the install. We'll need to help you out with some contacts for the mounting bracket for the blower and that's about it.
5. I recommend either Fox Lake or TEA for heads. Yes, ported 2v heads are plenty, and the blower makes them almost a non-issue anyway. Still, the 5.4 block needs as much flow as you can get from the 2v heads so stage 3 race porting is good. You're not going to have to worry about low end grunt anyway.
