Just wondering if anyone is running a newer 5.4L modular engine in their early Bronco? Seems to me like it could make a real nice combo!
I also have a 2001 f-150 running a 5.4 with 141,000 miles on it and it runs just fine. I get 17-18 mpg if I set the cruise and just leave it alone and this is in a rig much heavier than my Bronco. I've head the overhead cam VS pushrod engine debate before and I pretty much chalk that up to a wives tale. Just look at the numbers Mustang guys able to get from these engines. The bottom end is also extremely stout!! They claim 100HP per Liter stock. I think with one of the 3 valve engines with the variable valve timing and a decent low end set of cams a 5.4 would impress quite a few people. Look at the TQ and HP numbers of these engines compared to say a 1995 F-250 with a 5.8L in it. These engines are also very smooth running.
I have had 2 5.4 trucks and they have no balls at all.
You have to reprogram the 5.4L 3V to realize their potential IMO. The factory programming is not much improvement over a 5.0. I am on my third one and I really like them reprogrammed with a little fresh air. My 2010 (I am about to turn in because it has a lot of miles on it now) will smoke the tires in first gear, and second. With the right programing they approach 400 hp and drive nice for a stock motor....With that said, probably not a very good choice for a Bronco as everyone else has said...much better and less expensive choices out there to waist the time and effort required to muscle one of these monsters into such a small engine compartment IMO.

X2 as a Ford tech I can tell you the "mod" engines have been great but for the time and effort to put one a Early Bronco I'd just go with a healty 351 based engine. I always feel the need to tell everbody about the evil's of K&N filters also, do a little reading on the web and you'll see some of the problems they can cause. I've sold quite a few engines over the years due to K&N filters, mostly because because folks install them and don't maintain them.
What programmer do you have? I have a K+N air filter and just added a Flowmaster muffler on my 2008 5.4. So it is breathing easier now and could probably benefit alot from a programmer. I did pick up 0.5 mpg with the Flowmaster.
I have a 5.4 in my 06.. And I am less than thrilled... B/t the nightmare of changing plugs, now cam phasers going bad...all at 123,000 miles.. Always used synthetic, changed every 5k.. Wtf..my brother is a ford tech for past 20 yrs and also hates the 5.4 motors
