Congrats, great looking truck.

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.

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

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.

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?
