So is this a dished or domed piston?

No, this is a motor for SS/Modified. Pretty much all of the dome and smallest combustion chamber and still getting enough valve relief gets you in the 15:1 range. I currently run the 2.3 Ford single cam engine but am in the process of building a Duratec motor which is an Ecoboost without the turbo.

Is the stock piston from Ford a dished or domed piston ?

We just got a 2018 Ecoboost 6 speed in today at work. K/S?

AND this Mustang is one of the whole new generation of Stockers.

More to come..

The classification guide does not list the 2018 Ecoboost Mustang, so if you wanted to run it, I think you'd have to back-date it and run it as a 2015 model. I know the nose is different, but I don't know what else is different.

If you're able to run it, it would be a natural J/S car at 12.78 pounds per factored horsepower. You could add or subtract weight to run one class up or down (K/S or I/S).

If the one you have is a Performance Package car, they have larger/heavier front brakes than the non Performance Package car.

Have you driven it?

I want to see Ecoboost Mustangs heads-up racing Ecotec Camaros. Stick only and we could call it Jr Factory Stock. It would sound like a swarm of mad bumblebees

I didn't drive that one. I did drive a 2018 GT350 a couple of weeks ago. Pretty quick and I like the sport mode for the exhaust.

I don't think the GT350 (or it's flat-plane engine) is listed in the NHRA Stock Classification Guides, and it's only available as a stick-shift.
