What's wrong with that? It will get cleaned and machined and new parts where needed.

Because they could probably do that for his and it would be a lot quicker.

I always have mixed thoughts with warranty. Do I act responsible and inform the dealer I found gear tooth or do I let it blow.

I'd rather get a long block than a short block.

Most dealers don't have a clean room so I wouldn't trust a dealer rebuilt. They sure as hell won't send it to a real engine shop.

I don't think Ford feels their Gen 3 engine CS are in need of an upgrade.

Well, I beg to differ

How does Ford dealerships get the blocks? I'm assuming everything's already set up for them..

Does anyone know this?

They come from the assembly plant.

Does Ford offer an upgraded CS?

Thanks. If or when I change out my CS and OPG I will go with racing shops with a Good reputation for High Quality Parts, and Not Chinese Parts

Good idea.
Boundary lists the sprocket as 2015-up

I’m a bit mystified with Ford Performance statement about No Gen3 sprockets when in fact the OEM part number covers 2015-20.

I’d chalk that failure up to the keyway slot and key. It looks bad and the break is right on it. Weird

KR3Z-6306-B

KR3Z-6306-B

Replaces KR3Z-6306-A
What about KR3Z-6306-AA
By no means am I trying to split hairs over A vs AA.
I'll wager the OP's crank sprocket fractured at factory test startup or before.
With the sprocket held in place by the harmonic dampener hub I think this motor would've kept running for many miles. If the oil was changed by anyone else the OP wouldn't be any wiser to the condition of a fractured sprocket. Makes a person wonder just how isolated is this problem ?

My question to all readers, Is there a geometric difference in this crank sprocket from 2015 to date ?

Boundary and MMR doesn't list it as unique.
