That's pretty cool, and there is nothing wrong with going outside of the crowd, cause that's how some of the best successes have come about is going outside of the normal. Those are some sweet looking broncos too! So did you have a great time visiting with him?

Happy birthday! Just don't call me saying there is snow in palm tree's......that's the earliest call I've had in three years of college.

I missed it too, but been busy, happy birthday man!

That's probably why mines so quiet, how much were the dual high flow cats?

Right now she sounds about as loud as a poopy flavored lolly pop is good, haha. What kind of cats are you running? Right now she has about a 200 rpm range she rumbles, but my 99 was louder at start up, or so it seems to me, Start up she runs real quiet. Guess we'll see, may need to do cat delete...

Well, got the flowsound muffler similar to docs on, basically a flowmaster 40 original. Truck straightpiped was quieter than my 99 4.6 with dual flowmaster 40's, and with the muffler on, it's barely louder than stock. Kinda sad a 5.4 isn't all that loud. Oh well i guess, least i didn't do duals...

Glad you found the problem! Now I need to do some modifications to the exhaust on my truck, haha

Yikes, I'd rather go scrounging junkyards to find a decent tailgate!

Hell, that's what my 2002 F-150 gets on average stock. :headbang:

Holley carbs are known for getting terrible gas mileage. I ran a a Holley 650 or 700 double pumper on my 78 400 with a Edelbrock single plane intake, but that was for performance and not efficiency. Changing out carbs would help out some as others have said.

I just know about the engine, and that's why I'd pick one up, slap some good forged internals in, twin turbo's, and hell yeah, have some sleeperish fun!

You have a very good point Ernie, don't forget F-150's had some sort of air suspension option, at least I seen that in the owners manual etc.I'd touch a Mark 8 for one reason, hijack the engine, and be on my way :wasntme: But that aside, the air suspension leaves you :hammer: :headbang:

I would do no such thing.....haha, ok maybe i would get ya in trouble...It's always a good platform for the future when you consider a rebuild if you keep it that long. 300hp is a good number out of a coupe, and plenty for a daily driver. Too bad the 5.4's never had B-heads :wasntme: If so...

Your welcome on the info bro, try to help out. It's a good engine, and I don't believe the DOHC's have the problems that some of the SOHC's have. Also depends on what you plan on doing, but always a good engine candidate for boost. Believe it's a 6 bolt main block smilietease , but if you go...

The benefit of the Mark VIII's is that they have the 4.6 with B-Heads (2 intake ports per cylinder) and is the Teksid block, which is considered the strongest aluminum factory block available, and well, the B-heads are great for flow, and usually applicable in the boost scenarios. I'd suggest...
