Come now. Everybody knows that the 300c.i.d. inline six was constructed based off of recovered U.F.O. technology from the Roswell crash.
Ok. Seriously. That motor was the little engine that could. Insane durability (300k mile industry rebuild standard) and gobs of low end (not peak) torque. More than the 5.0 and roughly comparable to the 351/350's of the time. Is what endeared the motor to U.P.S. for over 25 years. Alot of people didn't know this but the 5.0/302 V-8 never made it past the F-250 while the 4.9/300 I-6 was offered in the F-350.
It definitely had some limitations as you pointed out. But a little time behind the computer could easily rectify some of the issues that motor had in the past. Power included.
Get real guys I suppose you are going to compare a turbo diesel to the 6 cyl gas pot!!!!!!!!!! Give me a break!!!!!!!!!
In inline six is still a stronger configuration compared to a V block, turbo diesel, or gas engine. As was said, six pistons for seven main bearings in an inline 6, compared to five in a V6, this is true no matter what it runs on.
Personaly, I like inline engines because they are easier to work on and more cost effective. As for the 4.9L, it could just be one of the best engines ford ever made, even if it is around half a century old by now.
For the 4.9L to be brought up to date, all thats needed is to rework the head for more flow to get better max output. A 4V head could be a solution, with so much low end torque, I think this engine still has a lot of potential

What was needed was a cross flow head, which they did do some development work on but never released it. And I'm sure all the tooling is long gone so don't wait for a new 4.9l.

No, I'm not waiting on ford to do much that I would agree with, but what if some one were to build a custom aluminuim head like what is avalable for a 302?

Nope. Not at all. But the 300 inline 6 was about as close to a diesel engine using gas for fuel as you are going to get.
Oh yeah. Your the guy who made the original comment. Tell you what. Find an F-150 with the 4.9/300 and jerk some stuff around for a bit. Then come back and comment.

That's great and all...and all over the forums I hear posts of people getting better MPG with a V6 than either V8. My personal experiences differ...
My old truck was a 2003 F150 reg cab, 4.2 V6, auto, 4x4, 3.55s.This truck was a dog. On the highway, she just would NOT keep speed going up hills without downshifting. Didn't have cruise control, power windows, or power anything...my only option I paid for was that 4x4 lever on the floor. Anyways.... My best MPG ever with that truck was 19 on a road trip...my WORST highway MPG was 12(!!!) on a road trip... The 12 was starting at -23 degrees farenheit, and filling up after 400 miles at 12 degrees, so I think the cold weather had something to do with it.
On the contrary...my curent truck, an '07 Screw has the 5.4L V8, 3.73s, auto, and weighs nearly 1500 lbs more. Best MPG was 21.5 on a road trip. Given, it was warm weather, but even in warm weather my '03 couldn't even touch 20. Second tank on that trip was just over 20, but I can't remember.
So....my point is.......
The V6 is supposed to be a low-cost option. Like it was in my F150, as that V6 made it cheap enough for me to buy brand new at 17 years old. Got better city MPG than my current truck, and outside of highway duty it did a great job.
Most buying the V6 are looking at fuel economy, a good value when they buy the truck, and aren't looking to tow 6,000 lbs with it. The 4.2 would easily handle that truck all the way up to it's max gross vehicle weight and beyond that...waay overloaded that truck a couple times with 2,000 lbs of wood pellets...and that V6 did just great.
Why mess with a good thing? Most looking for performance are going to get one of the V8s offered, and most looking for a cheap half ton would be more than happy with the V6.
Just my opinion here...whaddaya think?

Sometimes a V6 just gets too small for the size of the truck and works to hard. Like I said earlier, a great idea would be to replace the V6 with a small V8(friend with 4.6 got 22 MPG on highway when I was with him), and use the V6 in the Ranger and cars, thats just my opinion. I have never rode in V6 F150, I am just going by what people have said about the truck they have with them.
my 2 cents, with todays tech they can make one screaming i6 gasser. and as for the trusty ol 300. i used to own one. and that truck could pull anything. after all i was in the 1, 2 and 350's. as for highway speed it sucked. but it still could pull any trailer i put behind it. it even had no prob pulling the 2 1/2 pellets of marble i put in the bed one time. The only real reason that it didnt put out more hp was due to the fact that it only came with the single barrel. i have seen people put 4 barrel cabs and turbos on them any they really came alive. the 300 was one bad motor.
