The spray liners to me are scary vs. a cast iron liner......I don't think the spray liner will have the durability of a sleeve. I feel it would be a Ford production process aimed at reducing cost. It's easier/less expensive to spray a liner onto the cylinder wall than to manufacture process a forge / cast a molten iron cylinder sleeve......I would have no problem paying extra for the sleeve. Either way I hope it's made in the USA.

As for pressed in sleeves vs sprayed on liners, pressed in sleeves any day!
What is up with this spray on S***? What else can they spray on? Clothes?
Boy howdy, there are some damn hot chicks I would love to see with nothing on but sprayed on clothing!

It's a revolutionary process that is most likely the future of aluminum blocks, period. The Nissan GTR also uses the same process.

It's not sprayed on like paint, it's molded on. Ford isn't stupid (although they have done stupid things) They would not apply this process to a GT-500 when they know it's very popular and easy to pull 800-900HP out of these motors without touching the internals just a simple blower swap

I wonder if it is possible to heat treat the surface of the cylinder walls? Probably this with a combination of the plasma arc cylinder treatment might add some durability. The heat treatment I think could actually treat a few mm below the surface of the cylinder walls, which would be the foundation for the plasma arc treatment.
I know in WW2, US battleships had their armor plates surface heat treated so that the outside of the armor belt plate was the hardest and the side of the pate that faced the inside of the ship was a little softer to prevent metal shattering and spraying the inside of the ship with steal fragments from an explosive or concussive hit.
Totally different application for cars, the process used for old battleships.
But I wonder if for the grade of alum alloy Ford uses or the block if it can be surface heat treated to be as had as possible and then coated with the plasma treatment to help seal the heat treatment and to help give the block better reliability?
I could be wrong in my thinking in that the plasma process could negate and ruin any alum heat treatment processes.
