Engine Differences of the 350R

[Hack]

That’s not enough to definitely say that they are the same. I work for a magazine and I’m telling you what we would do in this situation. You could order both and return, or ask to see the differences. All that the Ford part number says is that the parts are interchangeable. Which they would be, but to say that they are the exact same you would need to see both units, or at the very least contact NXT and ask them about the differences that they talk about.

How do you think Ford is going to order/build/inventory/etc. two different components if they have the same part number?

Why would FR assign a separate part# to a factory Ford part? Is there a history of FR doing this with other Ford factory parts? Seems to me if a part carry's a FR part# then it's a racing part and not like the factory part.

Once again. I’m telling you what we would do.

I talked to the guy, wrote down what he said. So far we have info from the reporter. Who was on the line and what the line workers said.

Now we other people who are mentioning information from a parts guy at a dealership.

And from this we have people saying he is wrong or that is reporting was “pure speculation”.

I am saying: Check, and more than just asking a parts guy at your local dealer.

There are many parts in the parts computer that only have one number. Possible that the correct part is not listed, or that it is based on vin number.

Still. You guys could do more looking into the fact of any difference or if there is a difference than what is being discussed here.

Gotcha.

I don't know really, I found this item
under the usages: 07/13/2015 - 08/12/2019, Mustang, MOD 5.2L-TIVCT PFI NA HP1 GAS

There are 45 parts that the two cars do not share, none of them are engine parts.

I did find a difference I want now.
Shield - Splash Part #: 2K005 Front Brake Discs and Calipers MSRP: $74.64
Usages: LH, 10/02/2017 - 08/12/2019, Mustang, SVT R Model Series Brakes

I like to think that one of the factory workers walks down the isle of engines with an R divining rod with a red stripe down the middle of it and when he feels the stronger voodoo spirit pull the divining rod towards one of the engines he whispers “R” and the giant R-claw comes down to pick up the engine. I don’t have any evidence to back up the theory, but it’s how I like to imagine the building process.

So there we have it.
Like I been saying, all voodoo engines are the same between both R and non R.

Let’s go sit this theory 100%. It makes sense to me.

I think you hit the Nail on the Head..

I was able to enlarge the Magazine image

The two part numbers that show up
FR3E-6C524-CB This one is printed over XXXXXXXXXXXXXXX
GR3E-6C524-BA

Looks Like Ford Racing provided parts with their part number

Pure speculation on the Authors part.

@honeybadger

Can you take a picture of the face of your VCT intake phaser head as shown above? Yours is the only GT350 non-R I know of that's purely torn down and has easy access to this.

There's two part numbers on that phaser, if yours only has one that shows a difference between R and non-R engines.

The Ford online parts catalog, whether Fordparts or dealer website, are rather deficient in regards to the GT350. Even with a "R" VIN, they will show Coyote part numbers. The cam phasers and lash adjusters are only a couple of examples. The part number on the cam phaser photo above (FR3E-6C524) is for the 5.0 Coyote. Actual part numbers for the coyote are FR3Z-6C525 and FR3Z-6256. The GR3E-6C524 is the GT350 phaser (actual part numbers GR3Z-6C525 and GR3Z-6256). Ford Racing will bundle parts such as lifters, rocker arms, valves, phasers et. al. but they are GT350 production parts.

 

[bauern]

I just want to add that it is possible that the phasers and lash adjusters were changed in later years and that the '16 - '17 GT350's actually used Coyote parts. They are identical except for internal revisions.

Your wish is my command.

Interesting! Also, impressive response time!

So based on this, the GT350 utilizes a 5.0L Coyote phaser. Maybe a new item for your build, honeybadger?

The GT350R rebuilds the phaser with special specs, stamps out the FR3E number with the XXXX's, and assigns the GR3E number (which is also, apparently, the high performance part sold by Ford racing).

FWIW, I used the Ford Racing kit. The only part number on it is the GR3E-; no XXXXX's .

Yep, bit odd that they stamp over the FR3E number on the GT350R phaser but replace the plate on the Ford Racing kit.

Probably just a cheap cost save on not needing the replacement plate for the GT350R, and to make the Ford Racing kit part look better?
