Get the Bilsteins. The front left should be in stock soon or Summit may even have a couple. The front right is usually in stock. Rears always in stock. 

You have a couple of options. Buy the whole assembly springs and all. Then, it is a simple R&R job +alignment. Or, buy some better struts (Bilstein) and have a shop do the spring R&R. Then just bolt them in and do an alignment.

Get a different engine. There are no cam bearings as the cams run on aluminum of the head. So, if the engine is locked due to lubrication problems, the heads are smoked too.

That would be a tough call for me - I would prefer a remanufactured from a place like Jasper for $500 - $6000 but with that cost being 70% + the value of the car is where I'd have a hard time, and this might have me consider a cheaper fix and plan for a replacement vehicle in the near future.   Ford V6 3.5 EcoBoost | 3.5 Duratec | 3.7 Duratec | JASPER® Engines & Transmissions 

the engine has 180K on it   Might be good just to pull the engine to see what it damaged - Thoughts?   is there a good resource for the build on this engine?

The right front sway bar link broke off on my 2022 ST-Line with 50K miles, got caught in wheel and ripped off the strut mount. This means new struts will be needed to fix a $40 part. Dealer quotes about $2300 for both sides to keep Motorcraft parts. Private shops quote $1500-$1800 using Monroe strut spring assemblies. I can do that myself and then get an alignment. I would prefer DIY using Mototcraft assemblies, but Ford only sells the components separately. Are Monroe's bad? Other options are Detroit axle and TRQ assemblies on Parts Geek.

I found a piece of textured carbon fiber wrap left over from a previous project I am going to apply in the next couple days. I am wondering if forged carbon would be better to hide scratches and blemishes better.

What's in that kit is what I'd call a "refresh" not a "rebuild".   What's the mileage? Locked up due to lack of bearing lubricant would also damage the crank and would need machining or at least polishing, then what about pistons and rings?   A used motor with similar mileage would likely soon need a rebuild?

For $580, I think I would do the rebuild.  Especially if you are doing the labor, or have someone that can do it relatively inexpensive.  With a used engine, even if you could find one as cheap as that rebuild kit (and possibly labor), you take a big chance not knowing what you will get.  With the rebuild, you know what you have in the engine and the quality of the work.  Just my 2 pennies1

Thank you soo much! Our 2014 kept getting rated turds in it and dust coming in from driving down our dirt road... found your post and yup- took off the bumper and they chewed the same thing and knocked the filers down.. Thanks again and Semper Fi !
