ram 6.4 hemi

[mowin]

Just picked up my 2014 ram 3500 srw crew cab with the 6.4 hemi. I have a little under 300mi on her, and still going easy on her. Very impressed with tbe power.
More low end grunt than my GMC 6.0. Hooked on to a 12k trailer with a mini ex, and this thing handled it great.

Smart move going with the 3500 SRW vs a 2500. What gears and does it have a 6 speed or 8 speed tranny? Any mpg # yet? I had a 2003 2500 Hemi and it never broke 12 mpg with 3.92 gears and the old 4 speed auto. 7.5 to 8 towing.

I opted for tbe 3.73 gears. It has a 6 speed tranny. I dont tow heavy very often, so these will work for me. Computer is showing 13.4. That's combine hiway and local roads with about 30 miles of towing 12k.

Check that computer. I found my dodge had a optimistic computer. If it's really getting 13.4 that's not bad for a Hemi.

My grandfather told me when I bought my Hemi, he owned a Chrysler/Jeep dealership for 40 years and now that he has passed his brother owns it so no bashing here, that "Hemi was a Indian word for fill this mother _________er up again".

It will be interesting to hear your numbers. Both my trucks are getting at the point for me to trade. I currently have a gas and diesel and thinking about going back to just one. I am tempted to go 1 ton SRW 4x4 gas as you did.

The 8 speed is not available in the 2500/3500 trucks. I know a few owners of these trucks and they are returning very respectable mileage. Similar averages to what you are seeing.

Congrats on the new truck.

Keep us posted on the MPG. I have an '09 2500 Cummins and I don't tow often. I get 16/19 mpg,
It's a Quad cab and I'd like to get a Mega Cab with 6.4L.

Not sure if you realize but for some reason ram detuned the 6.4 for the mega cabs. Somewhere around 40 hp and tq less.

I've heard the computers can be off, I will definitely hand calculate the next two tankfulls and compare #'s

Didn't know that! Dumb move.

I think your mileage will improve a little. I've done some reading on a Dodge Ram forum and people seem very happy with their 6.4 trucks.

yeah I test drove SEVERAL 6.4L powered trucks recently.... VERY IMPRESSED with the more linear torque curve of the engine vs. the extremely "peaky" curve of the 5.7L.
The little 5.7 doesnt really wake up until about 3500+ RPM the 6.4L actually feels more like a diesel... really good grunt off idle.

It's about time they started making truck engines WORK like truck engines, instead of hopped up street car engines.

I am impressed with how many GOOD trucks there are out there across the different brands.

Yes. I hated my 5.7 Hemi for that reason. It could not pull my 8,600# boat I had at the time without living near 4000rpm with the 3.92 gears. One of my buddies had the same truck a few years older then my 03 2500 but his had the 360. In my opinion a much better truck engine.

I researched stroker engines, some time back and came across a fully documented build of s stroked 350 (380 I think) where the guy built it for trucks. It produced like 385hp and 450tq. The nice part was on his dyno sheets. The tq was 400 at only 2000 rpm, and gradually worked to 450 at around 3500.

That would be perfect, and then gas engines could be far more useful in a working truck. Of course they would still have to offer the high hp high rpm models for folks that never actually use it for heavy work, but like to brag about numbers.

The big downside is mpg's, as I am sure they will not be the greatest, even empty. Such was the case with Fords old 300ci inline 6. Great pulling power, not much top end, and not much for mpg, but a great work engine.

With all the computer controls and advances in injection systems, maybe they can make some big strides towards correcting that.

Is the 6.4 Hemi a push rod engine?

Can a pushrod engine have VVT?
