Sorry I did not do this yet (been focused on bronco raptor/ranger raptor 3.0 and 2.7 Ecoboost). Right now parts are piling up, and I need a solid 2 day wrench-fest to get things in a good place, hopefully early March

The ford system shows the part as fitting 2022-2025 f150 soo I’d be surprised if it doesn’t fit up

That’s a great point.  The hybrid variant might have some differences to the standard 3.5L worth exploring

Sadly my contacts that helped Full-Race with previous gen 3.5 projects left Ford during a mass re-structuring. As you’re probably aware they and many others left as part of a corporate mindset move away from ICE’s toward electrification.  A huge amount of 3.5 eb knowledge and experience gone

Agreed that 800+hp warrants consideration of cylinder support. However ethanol and soft ignition can go a long way at safe power production.  My only pushback to the CSS is the stock sleeve can still crack, it just won’t shatter (detonation typically).  it may be a safer bet than a ductile iron sleeve or it might also create headaches with sleeves moving.

Long way of saying 700hp is the reliable / safe ceiling I want to work toward and the stock open sleeve block should be fine with that.

Please let me know if he can do it?  I still think a dummy solenoid may be necessary
