My 5.4 Build
#151
To be honest I would go with a set of Comps or some custom specs cams. 96-98 Intake cams will help mid range power more than anything. 15 hp from cobra cams can be found in tuning really. Where as comps for example maybe good for 40-50 with a relatively conservative tune. Especially if the CR is increased. When i go to machine my long block it will be a 0 deck along with mahle pistons to bring the CR to 10.5-11:1. It will be setup to run E85.

How difficult is a head gasket, timing, and cam swap on these 2v's?

4v > 2v

I wouldnt say its too difficult, but you need to know what youre doing before you tear into your engine. Theres a little more things involved than just swapping cams and getting a lope..
Tuning, valve springs, valves, and torque converter are all a possibility depending on the size cam you get.
Head gaskets are pretty straight foward. Just remove intake, valve covers, timing components, and then heads. Replace gaskets and reassemble. Just be sure to mark all timing components so that they go back on the same exact way they cams off.
How well do you know your way around an engine? These 5.4s in particular...

Edit: I don't want any lope lol- just a mild stock replacement that won't require any modifications besides a tune http://www.modmaxracing.com/mobile/P...Code=COM102500
The only engine work I've done is a friend and I rebuilt his 454. The GM tech I mentioned will be helping me

I plan doing the complete top end: having the head rebuilt with some mild work, 262ah cams, lash adjusters, all timing components (chains, tensioners, sprockets, etc), and some cheap shorties to replace my rusty manifolds. I was worried about not having the tools but my is graduating from a certified tech and will access to everything except the specialty ford tools like lash adjuster removal tool. The plan is everything from the block up with be getting a refresh.

Go with a set of Comps. I have a set similar to the comps from SHM and they are great. No huge loss of vacuum, bet these were spec'd for my particular wants and needs. I have no need to spin these 5.4's or billet converters to 6000k rpms. I wanted torque which is what I got. My current configuration is making 295/345 to the wheels on E85.

No you wouldnt. It great to drive, does anything I need it to do, but will pass anything but a gas station. On E85 is get around 7 mpg's and around 10 mpg's on the highway. I have a tune for 93, but it kicks it the nuts power wise. But the mileage is alot better. On 91/93 it will get around 14-15 mpg around town an close to 19 on the interstate.. So anytime I plan on going out of town, I switch tunes.

I think my 4v plan just took a dump, by way of a bad block and a bad head. Both in the same week by different shops. :0/. I've got a blower here from another build, I think I might just slap in some MHS Torquer cams and be done with it.
I paid almost $2k for a warrantied motor but since I took it apart they won't exchange it. At the time I bought the 4v I was going to just drop it in so I wanted something that ran.
Now I remember why I parted out my mustang after it was done.

E85 needs 20% more fuel over all for normal driving and almost 50% more at WOT.
My 96 GT went from 580rw to 620rw with just a home brew tune and similar dyno days. Different dynes though.
It's just not worth it for anything but a track vehicle.
You'll get more hp and it's moderately cheaper than gas but you'll spend more time at the pumps.
Combine that with fuel additive mixtures being changed out up to 5 times a year depending on where you live, it'll really screw up your tune. I had 3 separate tunes prepared but eventually bought it by the barrel from some guy in Ohio or Indiana.
My buddy ran the fastest street tire v6 mustang in the world on e85 and even he gave it up. I firmly believe in if you want more power, just add more boost.
