Blah blah- dude you have a serious lack of reading comprehension. What don't you understand here? We are talking about big power. We aren't talking about what 95% of people do, or what the typical guy does, or what the OEMs are doing- we are talking bout making big power in a Raptor. Your truck came with about 10% more power than the 6.2L engine had- don't act like you got a ******* rocket under your hood compared to the outgoing engine.
I'll say this much. Hindsight is always 20/20. Instead of buying an '18. I should have bought a '14 and did the fiberglass conversion.
the Ecoboost is tuned too close to its absolute potential for it to have the same level of longevity that the 6.2 has.
I'll never get perfection out of any vehicle that i buy off the lot, and I'll use this logic to make me feel better about modifying everything that I own, new or old.

I know for a fact all Coyote engines have weaker blocks than the 4.6L in my 2003 Mustang. But please, go ahead and differ all you want- you don't have to beg.
Your Voodoo engine has great heads and intake and all that, fancy sounding FPC crank, yea, but if you want to make 1500 HP+ to drag race it, you start with a 4.6L based mod motor block and not a Coyote or Voodoo block. Actually right now there is an aftermarket block available that is better than any OEM Ford block, but when it comes to OEM stuff, the 05-08 WAP/Aluminator block is the strongest block ever put in any Ford V8 gas engine ever made, period.
Then as as I said, if you look at the way the ring packages were manipulated to create the 5.0L engine from the 4.6L engine, the 5.0L has less amterial to work with, therefore the ultimate power capability of the piston design is weaker. Again- fell free to differ with any tech to back it up other than you spent a bunch of money on your engine and it's fast.
All of what I'm saying only matters when you get into the 800/900+ HP range. Anything less than that is not really an issue for any of the 4.6/5.0/5.2 castings.
you won't catch me denying that the 5.2 block doesn't need a little bit of help. I ended up having my block sleeved by MMR. This was far more cost-effective than dropping 28K for a tall deck, 3500HP capable variant. Net/net, I feel that without iron sleeving, a 5.2 block will hold 900 or so HP. Sleeved, I feel like it will hold up to 1500-1600. ( in either scenario, you're talking racecar levels of maintenance.)
top ring clearance is the biggest pain in the ass problem on the motors. From the factory Ford sets them up "loose" and the ring/piston design is similar to Kieth black stuff where the top ring runs hotter and expands to maximize reflectivity and thus power. When trying to change ANYTHING to wick the thing up, you usually end up with either too much or too little ring clearance.
We had 4 different sets of rings on my motor before we found the sweet spot. (it eventually came down to ring material and its expansion properties and no so much the gap.) we opted to start with too much clearance so that there was not a risk of borking the pistons or cylinders, as I was unwilling to re-spend on a block, sleeving or pistons in order to support my engine builder's "testing".
However, If I ever need more than 600 HP in a prerunner, I'm doing something wrong.
If my ecoboost takes another shit and Ford decides to not cover it under warranty, I plan to go with a 5.0 or 5.2 due to the transmission compatibility. If a bellhousing is out for the 10 speed that gives me other options at that point, I will absolutely consider an alternative.
I think running a 5.0 or 5.2 for my scenario ( being that I'd like to be somewhere around 550/550 if I had my druthers) facilitates far more "performance overhead" than any ecoboost and I'd expect a lot more longevity.
When all is said and done, i guess I'll still come back to " WTF do you need "big powah" in a raptor anyway?" and that point is in no way, shape or form directed at you.
