I want one the newly designed 5.8 engines. I have heard they will have much better power, torque and new efficiency which will result in better MPG than the current 5.4.


If they bring this motor with the new 6 speed tranny that's the vehicle I'll buy. Diesel is 50 cents more per gallon here.

The new 5.8 will be all I need in an engine.

 

There's not going to be any 5.8 Boss/Hurricane, at least not for the first couple years. The 5.8 was going to be installed into special edition Mustangs, now it's not. Trucks are getting the 6.2.

As for the 300 I6. Good engine from a longevity standpoint, but they weren't flawless. I've seen numerous Modulars with 400,000 miles on the original engines, that rivals the best I've seen from 300 I6s. Like Modulars, there were many 300 I6s that crapped out at lower mileage, I've seen that too.

300 I6 had somewhat respectable low rpm torque, but they had absolutely no mid range or high rpm power. Pretty gutless in passing situations or pulling a load up a hill.

 

Are you sure? I've been told by several people that there will indeed be a 5.8 available on the 09's along with a 6.2 and these new trucks will be shown at the Auto show in Jan. and be out by Sept of next year.

 

The sticking point with the modulars (the 3 valve models) for me is the goofy spark plug breaking off in the heads, but rumor has it that you need to change them hot, instead of cold, which is not the typical proceedure for alloy heads. I like both engines, the 300 and the mod. I'd rather have the 300 in a truck and a mod in a car. I have been thinking of how I could drop a 2V 5.4L mod into my 1984 Olds 98, in fact. I want a truck that runs like a tractor, that's why I love my 300. But an efficient, high torque diesel with about 180-220 hp would be tops on my list, because while I love my 300, I'd take a diesel over it any day. If the 300 ever does let go, then an IDI 6.9L or 7.3L would be a perfect transplant, since they are (relatively) cheap, simple, reliable, and even torquier than the 300 at low revs. The diesels should be sold at varying power levels like in the big trucks... these days it's just software changes to get different power outputs on them. A high efficiency program with lower HP and better milage would suit many diesel buyers well. Not to say gutless, but do we really need 400 HP diesel pickups with way more power than anyone could safely use to haul a load? That's fine for some, and the aftermarket supports that. But let's get real. I'd NEVER put 9,500 lbs behind a 1/2 ton. I don't care what the manufacturer says, a 1/2 ton would be too scary with that much behind it. Further, in regular use with that kind of a load, it wouldn't last long. Pickups are coming with more HP than many over the road tractor-trailers have, and yet they move over 80,000 lbs. Kind of seems like overkill to me. Sorry about the rant, since I know it went a little off the subject, but I don't see trucks as a muscle car replacement like some people do, and it irks me that they have a horsepower war raging instead of focusing their energy on improving efficiency with gas prices skyrocketing and returning to levels of adequate performance. A 351 powered 1996 F-250 was no dog. Sure, it wouldn't embarass a Corvette, but is that a truck's true purpose? I'd rather have that level of performance with maybe 23-25 MPG in a truck. Seems strange to me that I can consistently squeak 20 MPG highway out of my truck, and get 17-18 around town, with nearly 290,000 miles on the ticker, and nobody I know with any new 1/2 ton can touch it, at least not consistently. I also don't drive like an old lady. I just don't whoop it at every red light.

 

Diesel in my area...$3.70...and I have a Ford Diesel
Regular grade Gas...$2.89
Uh...I'll take the gas engine!

 

Just let us know when your transmission goes out.

 

Hey, now, take it easy...of course if 5.4 is available for $1500-$3000 range, absoulutely, WE will drive 5.4 anyday, but that is not realistic, you know I know who selling Ford truck with 5.4 for that price? Meanwhile, 300-6 is available galore! in that range of price, so we just save 20k...that is even better, don't you think?

 

hp is a fake number... it's just torque x rpm divided by 5285... pretty sure that 5285 is right... anyway they're pumping 1800 ft lbs of torque at 1200 rpms... with that calculation that means that at 1200 rpms it's only running 400hp...

but it's pushing 8400 lbs along with it... that's VERY impressive

 

The piston engine has not changed in over 100 years. Every engine still has a crank, pistons, and valves. The only real difference is horsepower relative to the size of the engine. A smaller engine that works harder is not automatically more fuel efficient, or more reliable.

At the end of the day, I make a living with my truck, and I don't baby it. If given the choice, I will choose an OLD, simple, cast iron engine, but untill that day comes, I'm stuck with used trucks (none of which have ever left me stranded).

Oh, and I won't touch any pickup that has a peak torque above 2500 RPM (I expect even lower for diesel), and peak Hp should happen no higher than 4000, but thats just my opinion.

 

I agree with you David85. I want my pickup simple and easy to work on. plus some of the parts are outrageous in price for the newer enginee.

 

Positive.

Engine lineup at launch of the '09 F150 will be:
1. Duratec 37 (3.7L Cyclone V6)
2. 4.6 3V (w/ 6R 6-speed auto)
3. Performance Improved 5.4 3V (~325/385 w/ 6R 6-speed auto)

6.2 Boss will be a late availability 2009 model year (2009.5) option or possibly a 2010 MY option, will replace the PIP 5.4 3V.
4.4 Lion TD will be a 2010 MY option. (possibly late availability)
There is some talk of either a 5.0 Modular Twin Force or a Boss 6.2 Twin Force as a 2011 or 2012 MY option.

The Boss 5.8 was never going into the trucks, Mustang is getting a 5.0 Modular instead.

 

so i guess fords plan with the new engines is to take back the lead in kick *** engines which in turns would be kick *** vehicles. I wish i hadnt bought my 07 F150 i want one of the new F150 engines!!!!

 

I picked the diesel assuming it wouldnt have issues. But, with diesel being almost .30 more/gal. dont know if Id be saving much at the pump.

 

Make that 90% positive.

 

You arelucky where I live diesel is .60 more than reg. UL, on last nites news they are predicting diesel will be $5.00 a gal by summer 08, I'll take gas thank u!!
