Yes, it's a 13-14 GT500 blower. The number you see on Ford parts are engineering numbers, not part numbers. DR3Z-6F066-A is the part number.
I think that blower may not be considered aftermarket and still at the lower factored HP. The classification guide seems to indicate the higher HP is for a VMP blower.

EDIT: I see now that the "&" symbol under the various engine/trans combos refers to "& = VMP #VMPG3R-6H066-AA-23". As a non-CJ expert I did not recognize that as a supercharger model # and it would have been nice to have that info included on the page, and/or the "&" put after "S/SS Factors w/ replacement supercharger". Without that clarity I'm still somewhat unsure where the higher HP rating applies. If someone runs this combo with the DR3Z-6F066-A supercharger and can verify which horsepower rating it techs and races under that would be most helpful, otherwise I guess I'll cross my fingers for a clear answer from NHRA.

Another way to verify would be with Ken, the site owner here. He runs that combo. The Nitro Joe stats show him at 569hp, and in this video you can see he has the VMP blower.
Still kind of leaves the question is the GT500 blower also at the same HP as the VMP but I would guess it isn't. He should be able to answer that though.
