I'd say he is agreeing with your post about finding a 6.0 and putting the money into that versus a high mileage 6.4 truck.
Ahh I see.

a full rebuild is $10-15k easy on a 6.4 and can go up from there if you want to add any performance goodies
when I buy a 6.4, I either buy one that needs an engine for $15k+ below retail
OR
I buy one from the original owner that's been meticulously maintained so that I don't have to touch the engine...
buying a high mile truck from somebody who has only owned it for 35k miles and is unloading it after pumping a bunch of money into mods sets off more red flags than I can count... and I don't buy 6.4's that have ONE red flag!
I absolutely love 6.4's. When you get a good one, they're awesome. They're easy 300k+ mile engines when they're maintained correctly and not abused.
The problem is that idling them and/or extending oil drain intervals is abuse, and a lot of folks didn't/don't realize that. Tuning them and beating the tar out of them is abuse... if you blow a head gasket on a 6.4, you're abusing it... if you over-torque a set of head studs and crack the block, you're abusing it.
There are so many things that can go wrong with a 6.4 that will really eat your lunch. You have to execute a lot of diligence when shopping/buying one.
a 6.0 requires a lot, but you can "redo" the engine for less than half what it costs you on a 6.4, so it's less critical.
6.7 trucks are expensive, but the engines are tough as nails, and if you do have a major problem, the engines are cheap as dirt to replace

Im so glad I didn't pull the trigger on this 6.4 (that was a good deal) I thought I had to have a couple years ago. If I didn't score the low mile 7.3 that I have now, Id be in an 06 6.0-- some days, I wished I had the 6.0. No fuel system issues of the CR engines, but its much more refined than the 7.3.
Some good advice in this thread from some guys that have been around the block...

I always hear talk of the CR fuel system issues...
yet we replace 6.0 injectors at a rate of about 100:1 vs. 6.4 or 6.7 injectors...
high pressure pumps at about 20:1 for 6.0 vs 6.4/6.7

if you want 600hp, I'd just buy a clean 6.4

Put a tuner on that 6.0 and drive it. Or you could spent 15k and make one really sweet truck that will be worth very little when your done. With a hot tune it will run very well, spin the tires drift if you want it too. I came to the realization that i could make stupid power for pennies in a mustang or fbody when compared to the cash it would take to make my truck relatively fast. Once you dump that much onto making huge power youll have trouble pulling a jetski to the pond. Which defeats the purpose of the truck. So i run a race tune most of the time and swap tunes to tow. Havent had a issue pulling anything 80+mph if i want either

We just put a stage 1 pmax on an 04 that has studs and duhl8s already. Threw rcd 190/30s in. It runs nice. Right around 550-570hp. No smoke either. It'll puff a bit and then its clean. Burn rubber all day long.

Bought my king ranch 6.0 with 204k miles for 11k 3 years ago. Once it was studded I put good tunes and an exhaust on it and it made a ton of passes in the 13.8s. Now it has 238k on it making 11 second passes with the same engine.
I outran many many tuned 6.4s when I was tune only (they had crappy tunes, big tires, chitty driver) with a 6.0 that's properly studded it's just basic stuff to outrun a tuned 6.4. Hell if you're not afraid of nitrous a friend of mine runs 12.6s with a stock turbo/injector 6.0.
