Need advise! Should I repair my 6.0 or swap in a 12v?

[Dunecruisin]

I have an 04' 6.0 with 174,000 miles and it has started loosing power while under load towing my 8k trailer. (Runs great untill I start pulling a hill them starts surging) No smoke, no codes, new fuel filters, new oil cooler, egr has been deleted. Loosing coolant out the degas bottle but my eot and ect are always within 5-10 degrees. Maybe blown head gasket? So do I order the parts and tear into a headstud job and possibly injectors? Or I have a really nice 94' 12v dodge engine with 250k on it that is sitting in my service truck that I could swap in? I know that the 12v would be more time and money but from what I've heard after doing this it's bulletproof. Or is it best to fix up my 6.0 and see how many more miles I can get outa her?

Thanks for any advise!!!

you know, the cummins is a solid motor, but i have a lot of faith in the 6l's I say fix it

sounds like you're in for a HG job unfortunantly.

I vote put ARP's in it and it'll last as long as the 12v- without all the pain of the swap, and less $$$

As much as i love my 6.0 i doubt they will last as long as a 12 valve .

gaskets, studs, delete, filters, coolant, bulletproof 6.0L

Leave the 12V in the crate it came in.

Common Rail screw the 12V. thats the route I would like to eventually go.

depending on who you get the adapter stuff from, how much you do yourself, etc: It seams like you are actually either equal money or less to swap the 12v vs. head gasket, studs, and injectors, with associated machine work on heads and block.

So I guess the question is what will last longer, a 12v with 250k on it right now, or your 6.o with all that done?

The 12v will get a lot better mileage though.

For what its worth....No matter what all the hype is out there,,, EVERY motor will have its pros and cons! Ford,,Dodge,Chevy... My thoughts are~ stick with what ya got,, just do the repairs.. If you do go with the 12 valve,, and you have problems with it,, you will kick yourself for not doing the repairs on the motor you originated from. Im not having big problems, KNOCK ON WOOD,, but I am going to do these thing real soon! Seems to be a bit cheaper than the 12 valve over all...

Well Ill be honest thats a tough one! I LOVE the ol powerstroke.... but its real hard to say anything bad about a cummins. soooo basically Im of no help! LOL Either way you go you'll have a real nice rig! if you go with the cummins Id carry a camera in the truck to capture peoples faces when they hear your truck. its funny to watch people when they see your truck and expect to hear a powerstroke and they here that cummins rattle it always takes them a bit to figure out what the hell is going on. LOL
