What has everone experienced to be the single most gain in HP other than a supercharger or NOS. Heads, intake, cam?

heads/cam combo but you will need an intake manifold to so the heads can breath

What do you find to be the best combo for a stock displacement 5.0? I want to stay emissions legal and trouble free.

if you can't afford either, I know it's not "horsepower" but a set of gears would make a very big smile on you face

If you're trying to stay emissions legal, go with a 64 cc or so chamber to keep CR down; but you could probably pass with the 58's. Bolt on a set of AFR165's with an aftermarket intake - I'd go Cobra/Explorer/GT40 - and a set of long tubes with high flow cats/exhaust system, and a set of 3.73 gears. Add a pair of subframe connectors, and a decent maf/throttle body and you've got a car that's capable of stock drivability, emissions and fuel mileage (maybe a tad less on the highway) but will run MUCH better than stock.

To me the GT-40 and Cobra intake look entirely different. The GT-40 looks like individual tubes where the Cobra looks more like a stock 5.0 intake. Which one is the best?

This doesnt work for everyone but best gain in HP I ever got was when I took out the 2.3L and droped in the 5.0

GearHd6 - look more closely - the GT40, Cobra and Explorer all share the same lower intake, and the lower is the bottleneck to flow. All three flow/perform almost identically.

Yeah, I forget where, but some site had flowbench comparisons and there was too little difference to matter - if buying one, buy the cheapest you can find.

It's hard to say what single mod would make the most power, because components need to work togeather and some "mods" requre more than one part. I was going to say Turbocharger, but then you need to get other mods to support it such as fuel upgrades, exaust modifications. I guess you could turn the stock headers backwards, add a turbo on each side, rig the exaust to mate back up with the stock H-pipe and I guess run only 5psi of boost with no intercooler and hope it doesn't detonate. Probally the add on that requres little or no other modifications would be a shot of nitrous, 80 shot or less, but not too big because the fuel system wouldn't support it.

I thought AFR's make enough power/flow enough air to require fuel system upgrades as well? Or is it possible to keep the stock pump and injectors?

Just assumed everyone knew the pump would have to be changed.....sorry. I'd stick with the 19's to start with. $50 for 3 dyno pulls with the wide band will tell you if you're outrunning them or not.
