R3d, how does that program work that you have? Id like to get a rough idea of what a
5.4 with flattops, with the navi heads(IIRC comp is about 9.8:1ish)
lightly ported navi heads/stock valves
96-98 cobra cams or 01 cobra cams
widened mach or cobra intake
stock headers(for a while) with x pipe and 1 chamber flows
full boltons
Kinda curiuos as to what I might expect to see. I know the mach1 guys are picking up 30hp with the 99-01 cobra cams so...

It's very accurate with accurate info fed into it. If you can get me the lift and duration and ICL and LSA for the cams I can work you out something more accurate. In the short term, expect 350rwhp or better and similar tq. I'd bet that with a decent cam set and good porting on the intake side you can see an easy 400rwhp/tq. Send me as much detail as you can about the cams, I'll figure out the heads and run you a simulation.

intercooler

water manifold (for the intercooler, not the crossover tube for the engine coolant)
lower intake
intercooler res
pump
heat exhcanger
stock lower pulley
I'm thinking around 1400? The lower intake and intercooler being the harder to find.

IIRC, all that runs about 4500 from Ford. Whatever you do, DO NOT ask Randy.. he hates that question cuz nobody ever believes him that it's not cost effective. I'm working on my Roush intake though and you could make that work a bit cheaper.

that's exactly what desktop dyno and all the results so far have shown. Stage 2 heads and cams and longtubes are worth up to 330 even with adapter plates in the mix... drop the plates and you may be able to find another 15hp or so.
