HELP: torn between buying a 6.7 and a 6.4

i just sold my dodge and am looking to get another powerstroke. i dont know very much about either engine and am looking for some recommendations as to which direction i should go. i will not use it as my daily driver as i like to use my little ranger for that, i mainly just use my "big truck" for longer trips, towing, or when i need/want to ride in style.

i do plan to do deletes and put a programmer on the truck but DO NOT want to tear into the motor to do studs, HG's, etc. wanting to keep it stock height or maybe leveled with 33" tires with 20s. towing will range anywhere from pulling my 4wheeler to pulling my 40ft 5er toyhauler camper (16000lbs).

both trucks look great with the newer ones taking it in the looks department IMHO. from my research the 6.4 has the potential to have more power tuned than a 6.7, but i worry about the longevity and reliability of it. i also have heard stories of the 6.7 breaking exhaust valves which scares me.

Either one will be great!
The 6.4 has more power potential but the 6.7 is a towing monster!

Unless your always pushing the 6.7 to the VERY linit, you shouldn't have any engine issues with valves

Tuned the 6.4 takes the crown in almost every catagory. The 6.4 deleted and tuned is a very reliable motor.

6.7 is a beast of a truck and reliable as heck.. The valve problems were mainly in 450's. It's hard to find a tuner with delete capabilities right now, well for a fair price anyway. Like I said 6.7!!

Tuned: hands down 6.4
Stock: 6.7

But you will probably get better fuel economy in the 6.7. That being said I wouldn't trade my beast of a 6.4 for any 6.7... Ever.

I would buy another dodge before I got a 6.7 personally.

I drove a 6.4 and then the new 6.7 and ordered a 6.7.

If you're going to tune, you may be money ahead to find a good used 6.4 as they will crank the power under a tune. There's no denying the power they can make.

However, a stock 6.7 with the 6 speed transmission is no slouch and I just love mine. I think the mileage is very respectable for a vehicle this size. The interior is fantastic and the truck is a head turner no doubt. It is a very capable animal.

I don't think you can go wrong with a tuned 6.4 or a new 6.7

Good luck!

Todays dealer lurking didn't help matters any, cheapest I've found was an 08 lariet 350 for 38k out the door. A brand new lariet isn't but 45k.

Personally, I would not own and drive a 6.4L without deletes and tune.
The 6.4L is a muscle car in a truck package.

My 6.7L makes me smile in bone stock form. And, it's way more refined and comfortable IMHO.
