You mean Don's T/A? I did check it out while out there over the weekend. They do want to sell it and wanted my opinion on value. I wasn't able to get under it to confirm if it's #s and asked the son to see if he can do that. I also am waiting to see what paperwork they have on the car before hazarding a guess on its worth.
He had a hemi cuda too but the family is planning to keep it at least that is their plan now.
They still have his 2014 or 2015 Ram 6.4 crew cab 2500 they would like to sell.
If you know anyone interested in either the T/A or the truck we can chat over the weekend at the CMC show.

That's right it is a T/A. We can talk this weekend...

Can’t wait for the show, weather forecast looks great!

Rhino did they give you a hassle about producing service records to show oil changes?

Not at all! I talked with Chrysler once, already had the trans problem so I had contact with them before which I believe helped in this instance. They were only interested in seeing my current registration to make sure I was still the original owner, and I had records for oil changes and maintenance at my original selling dealer, so they may have checked with them. I never talked with Chrysler again after the initial call, so the dealer that was installing the engine and my original dealer may have talked, but the installing dealer only called again when it was done.

If it has had it's maintenance performed at dealerships then it's already recorded and the history is available to any dealership. If it was being performed aftermarket or partially by the aftermarket then you might be asked to produce records to verify.

When I bought the truck and got the lifetime warranty I made a decision to ALWAYS have them do the oil changes and on time. Same with the other fluids and especially the trans with my track record. It is only $29.95 each time at my dealer, and it has paid off...

I use the entire 5.7 top end and cam as that induction system makes more tq per CID than the 6.4 top end. I run 6.4 SRT8 injectors and stock 5.7 computer and the fuel trim never adds more than about 10%. You would like it as there is no MDS when you do it this way. The real 6.4 trucks have EGR, less compression and less TQ than mine and definitely use more fuel, mine uses almost exactly as much fuel as my stock 2009 5.7 half ton. As for fuel I run premium when towing and regular when not towing, the only time I hear pinging or see it on the scanner (even with 87 octane) is when it is very cold engine and ambient temp, once it warms up a minute or two it quits, it's counter intuitive and I don't have an answer (maybe the timing is way more agressive when very cold?), I have built a couple for customers this way and theirs are the same (2009, 2011, and 2012). I just feel like with that much compression I should have to run premium even though my ears and knock sensor say it is ok. It is also much more pleasant to drive than a 5.7 as it don't downshift nearly as much now with the 6.4.

Everything was the same in the swap even the computers? Chrysler recommends Premium fuel for the 6.4, is that what you use especially when towing? My buddy has a 2021 with a 6.4 and 8-speed and I get MUCH better fuel mileage with my 5.7 than he does. BTW, put 1,000 miles on it today towing, not issues and I figured I should break it in the same way I did when I first bought the truck...LOL [/quote]

Interesting! As soon as they tell me the warranty is done I will have to start playing...THANKS!

Since you have a replacement engine,
and gasoline prices have recently made a big jump,
now would be a good time to try some aerodynamic mods
on your truck and enclosed trailer.

Start with something “dirt cheap”
like adding a “pool noodle” to the bottom of your truck’s front air dam.

Homemade “Wheeler Vortex Generators”

https://patents.google.com/patent/US5058837A/en?oq=5058837

or commercial “Airtabs”
added to the rear edges of your enclosed trailer
might increase fuel economy, and make the trailer ‘wiggle less” in cross winds.

I am sure that you have seen such mods on the 18 wheel trucks on the interstates.
