if you want fuel economy and durability the i still don't see why you wouldn't get a diesel (IF the premium for a diesel drops)
1)Pay much more $$$ at the Pump (.70 cents a gallon more in my area vs Regular Grage gas)...unless you work that Engine as it should be on amost a daily basis it's a total waste!
2)Their not the simple trouble free Diesels of even a few years back.
3)I would now dread owning a 07 or later...out of WARRANTEE!

Well actually, I already have one . Gets 20 MPG@70 MPH, and I can cruise at 85 if I want, I'll rebuild it from the ground up before I ever sell it (see my sig). Its not even running very well right now, needs an injector pump eventually.
Seriously guys, spend some time in the IDI diesel forum (pre powerstroke) and they can tell you the advantages of owning an older diesel that doesn't have a computer or emission controls.
But as far as new diesels go, these days, they're basically just used to ""power"" the emission controls, just like what happened in the late 70s with gassers, anything thats left is what you get of the flywheel. So if you want fuel economy, get an older diesel, or wait for the EPA, fuel refiners, and automakers to get their sheet together.
Back to the 4.9, I actually think this engine could be redisigned as a decent diesel, if it can deliver 20 MPG as a carbed gasser, imagine what is possible as a diesel. I have already heard of an aftermarket head for the 4.9 to get more top end Hp (still gasser). This engine has a 4" bore, and a 3.98" stroke, SEVEN main bearings, and a tough cast iron block/head, I think it has lots of room to grow.

even the 94-97 PSDs barely have any emmissions (in my case none ) and the computer doesn't seem to get in the way too much... i tell it what to do and it does it!! it's a lot more responsive too than my dad's excursion

No computer on my 1988 7.3 w/179.000 original miles on it! Bought it new, great solid Truck but it's killing me at the pump!
I had hi hopes of the new smaller Diesel for the F150 but Diesel will hit $4.00 a gallon in my area soon...nahhh I'm leaving the Diesels to someone else.
I'm done with them...unless the F150's get 50 mpg local driving.

Ford should bring the 300 back to life. If ford would put the 300 back into the f-series i would take it over any engine they would offer, even the diesel but, well its never going to happen. Why can't ford just listing to their consumers?
Yeah, I guess now that you mention it, the 300 did sell gobs more than the 302 or 351 in the F series before the 4.6 and 5.4 came out.
The 4.6 and 5.4 are worlds above the 302 and 351, and those 2 engines outsold the 300. What makes you think the 300 would outsell the (far better) 5.4?
Some folks really need to put the past in the past and grasp the present and future.
For me, if I can afford it, I'll be getting the 4.4L diesel 12 months after it is released to let them work the bugs out.
i have a 300 in my 87 f-150 that thing was amazing the truck had over 500,000 miles on it and still ran. the engine had plenty of torque and would get about 19 mpg. that was a great engine.

Are you kidding me? 500k? That is the most I have heard...on the 300. I have seen 400k up close, it was on an 88 F 150 in Arizona, but never see 500k!

while the 300 was great, there are a few things to consider other than the already mentioned emissions problem.
1. the weight of the truck. seriously, weigh a late 80s f150 and an 04+, and I can guarantee you the 300 won't move it past 60mph...
2. the more power you push through a certain displacement, the more stressed an engine will be. power comes at a loss of reliability, i don't care if the engine was designed by jesus himself. if they do update the 300 and give it enough power to be competitive with today's motors of it's size, i can guarantee you it won't be as reliable as it once was.
3. weight/size of the engine.
4. look at all of the fleet f150s if you wanna see some high mileage mod motor trucks. 400k is not uncommon. Most of these trucks are parted out sadly because no one in their right mind would buy a gas engine'd truck w/ that many miles, but they still run right.

19mpg?!?!? that's horrendous you can get that in my 7500lb f350 with the 7.3....

Well yes, but diesel are more efficient by design (at least before the EPA got to them), 19 MPG is pretty good for any full size truck in my book though, no matter the age, relative weight, or fuel type.

Hmm, I get that (usually 18.5, but I've reached 19) in my heavy a$$ '05 F150 Supercrew 4x4, 3.73. It is a lot heavier and has a lot more balls than the 300...plus more emissions controls.
So, I guess I fail to see where the 300 is such a super-duper truck engine. True, mine is newer, but it will out-pull, out-run, and gets at least the same gas mileage as the 300. Give me the 5.4 over the 300 any day of the week!
Well i know that the 300 will outlast the 5.4 anyday. plus I know i dont have to mess with the weird spark plugs. Also i know i can work on mine without taking it to the dealership.

I wouldn't put a lot of money on that. They are both great engines, but hook 6000 lbs behind each and see which one runs the longest. My money is on the 5.4.

I haven't had any trouble with mine. My '99 had the plugs changed at 100k and were still great. Truck was still running fine when I sold it at 136k.

OK, you got me there. You can work on your 300 while my 5.4 chugs along with only a trip to the dealer every 100k for a tuneup. Oh wait, I can do that myself with the help of a buddy.
I'm sorry, I just don't see the 300 as being superior to the 5.4 in any area, other than simplicity. The 300 is what it is: a simple, OLD, low-tech engine.
