Default Ford's new 7.3L 446ci engine

This engine really looks promising. In its infant stage now for aftermarket but that will open up pretty quickly I'm thinking.
Stock its 430hp/475lb-ft
Iron block
Forged crank
6 bolt mains
variable displacement oil pump

About the same size as 351w but 67 lbs heavier.

Road and track--->https://www.roadandtrack.com/new-car...th-basic-mods/
mustang and fords ---> Ford

I'll be watching closely as it may end up in a future build I'm considering.

Yes.

It almost looks like they've updated a deep skirt, crossbolt, side oiler FE427 with high riser heads, and a 428 forged crank !

Is it history repeating itself ?

Take a look at the attached links in my post. The top link has videos showing dyno + tear down details of all the main components.

The bottom link has details on internals after 3200 hours run time.

I get into the tech side of things so I really like seeing what makes it tick.

All looks very nice, but this statement of 9 cam bearings does not appear to be true, it looks more like typical 5 bearing camshaft:

"The cam features 60mm bearing journals, and speaking of journals, there are 9 of them to reduce or eliminate deflection."

It's just your usual tech writer getting out over the front of his skis ...

So, with this head design, with the intake ports nearly pointed straight up, is there much of an issue if you deck the block, mill the heads, with the intake matching up ?

No more so than any other 90˚ V style engine block.

The 4.6 Modular was built in 1992. It and all the modular engines, as well as the coyote, are of the same design. I never read anything specific on the subject, but if you took 0.010" off of the deck and head combined, each port would be 0.007" closer to the center of the engine. However there is no angle change, like you have to deal with on the FE, Windsor, Cleveland, type engines. The ports will still be level.

Yes, there should be no issue for normal engine rebuilds.
But if the heads/block are skimmed excessively for custom builds, then the ports will get closer by the proportionate amount.
