Oh ya, then why in motor trend did beside the f-150 recalls for 2003 it said none by the dodge 1500 it said quote "to many to list" doesnt sound like the beter engine to me and if there so much beter why has the f-150 witch even more expensive, been the best selling truck for fourteen years runing? answer me that buddy!

 

Some of you guys need to loosen up. Just because the hemi isn't a ford product does not mean ford is better. I have respect for all trucks. Each has its advantages and disadvantages. In this case, the hemi is clearly the more powerfull and ideal motor for a truck

 

Let's watch how we say things people

The 345 hp / 375 ft lb HEMI Ram truely dominates the F150. My long standing $100 bet still stands for anyone who wants to go head to head in the race of your choice (0-60, 1/4 mile, unloaded, fully loaded, etc.).

HEMI owns the 5.4L, waiting in Detroit . . . [/B][/QUOTE]

Hi.... I will take you up on that $100 bet. You get a Hemi, I'll get my 1990 Bronco and we will see who is who!!!

I'll be ready to race in 2 weeks...let me know!!!

 

personally i don't put much stock in that wards top 10 list. how can a motor be chosen the first two years of production? kind of hard to see how they hold up to real word use in one year. also who cares about a few hp's here and a few ft-pounds there. a motor that makes power down low is always going to outlast a high reving motor. i agree that the hemi's a good motor. in a car.

 

i look at it like this, an ideal truck engine would make its peak torque down low and hold over 3/4 of that until the hp peak and then shortly fall off. this way u get the low end grunt and still get excellent mid-range power all the way up until the peak ponies come in.

and personally i dont like the fact u need to really rev a motor constantly at 3500 rpm to provide maxium torque but to each is his own and like said above each truck has its own advantages/disadvantages. and people have personal preferences, thats why we live in the USA and have these different makes/models for us to choose what WE want/like, not what someone tells what is better...faster...more powerful...

 

Just something interesting that I found searching this site and a Dodge site. I found a couple dyno runs for both the Hemi and a 5.4. Heres what I found at the rear wheels: Hemi: Max HP-260; torque 281. 5.4: HP 230; Torque 260. About the torque curves: the Hemi seemed to slowly build it's torque, reaching it's max at about 3400 RPM and holding it there until about 4600 RPM and then slowly tapering off, and at 5800 RPM it was still at about 225 ft-lbs. The 5.4 however built torque very fast, reaching it's plateau at about 2600 RPM and holding it right there until about 4600 RPM. Then it began to taper off a little quicker than the Hemi. The graph ended at 5000 RPM with it's torque at about 230.
So draw your own conclusions, the Hemi does put out more power and torque, but it is almost 1000 RPM higher than the 5.4. I know that there are variables involved with dynoing that don't allow for the best comparison, like diferent dynos, temperature, barometric pressure, altitude, but it does give a good idea of the engines characteristics. I am just telling you of the two dynos that I've seen, so take it for what it's worth, I just thought you guys would like to hear some real world numbers.

 

There will be a bigger displacement hemi motor out in the near future. No Hp or torque numbers yet.

 

yea, another semi HEMI.

 

AG4.0, thanks for the data. It makes sense. The 5700cc is expected to produce more of both HP and Torque than the 5400, but the Ford is more effective at producing useful Torque. I don't like to rev the heck out of my trucks, so, I usually don't reach 3500 rpm unless I am really working a heavy load up a hill.

 

The new 5.4 3v feels like it has more power than the highly overrated HEMI. And the ford outweighs the Dodge by more than just a couple hundred pounds. In one magazine, they state that the ford will cruise almost effortlessly at 90 mph, while the dodge feels tired, and overworked.

just my $.02.

 

Just curious, but have any of you guys who are saying the 5.7 isn't really a Hemi ever seen a combustion chamber from one? The only major difference between it and the original 426's chambers are tha vave angles. It is not a pent roof design, the chamber is completely hemispherical. The valves are arranged in a top and bottom manner. The chambers look nothing like Fords closed chamber OCH heads with their side by side valve layout as one poster claimed.

If you guys are going to talk smack about the Hemi, you should at least know what your talking about.

 

Oh yeah, one more thing, have any of you who are saying the Hemi is over rated ever driven one, or are you just going by what you read in Motor Trend or something? I drove both the 5.7 Dodge and the 5.4 3 valve 04 F-150 before purchasing a new truck for my wife. I know the 5.7 is stronger than the 5.4. That is why there is a Hemi in my garage now. Any of you 5.4 lovers wanna race?

 

I'm just basing my comments on what a Dodge engineer said. He was the one that stated that they were not hemispherical. He said something to the effect that they were sort-of hemispherical with extra material on the sides. In other words a pent roof. BTW, the Fords don't have side by side valves. They are almost diametrically opposed and they are canted toward their respective ports.

Oh yeah, almost forgot. I wanna race!!!!

 

The only Ford OHC head that doesn't have side by side valves is the 3 valve 5.4. It's not even close to a Hemi either, so I really don't see the comparison anyway. All the rest ov the OHC motors have the valves arranged in a side by side pattern.

The Hemi heads have no extra material on the sides. The chambers are completely hemispherical as I said earlier. I've had a pretty good look at a set of heads that I had in my shop a few months ago. Trust me, their hemispherical.
