Engine Differences of the 350R

I also think its safe to assume the lifters as well.

Agreed. Good thing I ordered them a couple of nights ago

Good point, thanks for digging into this!

Good point, thanks for digging into this!

Yay for rational thought, due diligence and most importantly, DATA. I hope this satisfies all the folks this was keeping up at night lol.

To follow madlag up want to pass along a thanks for all of the effort! Read & reread thru this more than once trying to keep it straight in my head. Good stuff!

I added the A

From my buddy with a 2016 R

Pretty much confirmed at this point me thinks.

This would be correct for a 16 built engine. G simply means 2016 and could also be used in newer engines.

Another non-R owner confirmed the FR3Z in their car.

This could be from a 2015 or 2016 built engine.

@madlag 's R is a 2018 and has the same part

Anyone tear down an 18 350? Not keeping me up at night but I find this fun, in a weird way

Understood. But that could also mean supplier or inventory.

[GT350-H6088]

I worked at an automation company who installed lines at engine and assembly plants for the Big 3, so that's my background for this information.

No, the engine is not tracked to the chassis until the engine is already built, in the assembly plant, and "picked" to be placed on the dress line.

The assembly plants says "hey we need 50 gt350 (ha-557-aa) engines and 7 gt350r engines (ha-555-aa) delivered on XXXX date". So the engine plant builds per this direction, and ships them out. If the engines were identical, then they would say "hey we need 57 gt350/gt350r engines (same code, for example ha-555-aa) delivered on XXXX date." The assembly plant then organizes these shipping racks in the plant in seperate locations (floorspace taken up), and whenever a gt350 or gt350r is assigned a VIN, an engine is pulled from the rack. THAT is when the chassis/VIN and engine are tracked together, after the likely unique phaser has been built into the engine and the unique engine code is assigned.

My issue with having two identical engines with separate codes is that this needlessly takes up floorspace and time organizing/sorting the different engines. It would needlessly waste shipping rack space (empty spots on racks during shipping) as well. These aren't things that a large company like Ford would do.

If thats the case, then why would the Dealer Order a GT350 Motor for my 2017 GT350 and they ship a GT350R Motor?

I spoke with the Mechanic today on what sensor that he had to replace, I heard him wrong, what Ford told him to replace was the Oil Pressure Sensor Pig tail, there is a difference with the 2019 GT350R Motor's Oil Pres Sensor. The 2017 Connector would not fit.

I tried searching for 2019 Engine parts, there are none.

Explain.
You know that the letters indicate Year.
F=15
G=16
H=17
Etc.

It makes absolutely no sense to put different internal parts in either engine.
Especially when they see the same RPM.
If that’s the case they should of installed billet opg and timing gears.

Ist it possible sometime in 17, all GT350s received the GR part

Service is completely different from production. Part numbers can be different as well (GR3E vs GR3Z for example).

Without having access to Ford's internal systems, I can't answer why a GT350R engine would be sent for repair of a GT350, if what you have even actually is the 19MY GT350R engine.

My GT350 non-R will be here in early April. I will be able to share my engine code number to see it's base, and then we can go from there.
