Buying earlier block f16 and attempting to opgrade them.does not mean or becomes a block 52
F16 mlu is a inferior plane to block 52
The latter has the apg69 msa radar and the mlu the apg 63' .
Please go thru this link ,I think your information is little incorrect

Actually, a unique feature of PAF is that almost everything it gets is customized. Even when we got the blk 15 F-16s in the 80s, they were customized and were slightly different from the standard blk 15 that were sold to other countries.
Even now, the MLU PAF F-16s are getting are customized rather than standard MLU-3 or MLU-4.
Let me try to explain
MLU-3 in made up of the following.
Automatic Target Hand-off System (ATHS)
Integration of anti radiation missile capability
Integration of target designator system
Further implementation of the Digital Terrain System
Integration of the Link-16 system
Integration of capability for GPS controlled weapons (GBU30/32)
Introduction of Helmet Mounted/Cueing Sight
Introduction of NVG compatible helmets
Where as the MLU 4 Tape has the following features which PAF is not aquiring because of financial crunch,
M4 tape contains in addition to above:
Introduction of advanced short-range missile, as a replacement for the current Sidewinder (AIM-9X, IRIS-T)
Integration of advanced Link-16 functions
Integration of SNIPER targeting pods
Here's what PAF is getting:
The Government of Pakistan has requested a possible sale of 60 F-16A/B Mid-Life Update (MLU)modification and Falcon Star Structural Service Life Enhancement kits consisting of:
APG-68(V)9 with Synthetic Aperture Radar or APG-66(V)2 radar;
Joint Helmet Mounted Cueing Systems;
AN/APX-113 Advanced Identification Friend or Foe Systems;
AN/ALE-47 Advanced Countermeasures Dispenser Systems;
Have Quick I/II Radios;
Link-16 Multifunctional Information Distribution System-Low Volume Terminals;
SNIPER (formerly known as AN/AAQ-33 PANTERA) targeting pod capability;
Reconnaissance pod capability;
Advanced Air Combat Maneuvering Instrumentation Units;
MDE included in the MLU modification and structural upgrade kits
21 ALQ-131 Block II Electronic Countermeasures Pods without the Digital Radio Frequency
Memory (DRFM) or ALQ-184 Electronic Countermeasures Pods without DRFM;
60 ALQ-213 Electronic Warfare Management Systems;
1 Unit Level Trainer; and
10 APG-68(V)9 spare radar sets.
So you can see that everything there is just a customized upgrade rather then a MLU-3 or MLU-4. The only thing missing is integration of AIM-9X sidewinders(5th gen) because we are getting the AIM-9M sidewinders (the latest ones before the 5th gen).
Hope that explains it...so it is blk 50 standard
Once again paf is left with inferior planes relative to what they need especially as they are outnumbered 3 to 1 in fourth gen fighters
Not inferior to that time but too complex fighter in terms of foreign relationship as what i understand US doesn't just sell weapon they sell there strategic agenda`s with these
