Not to be fussy or anything, but there are some errors in this text.  It should read "AVCR-1790 diesel engine, not "AVCT-1790."  AVCR stands for Aircooled, variable compression piston.  Also, where it says "AVCT-1790", it should say "AVDS-1790".  AVDS stands for Air-cooled Vee configuration Diesel Supercharged.  Also, while I know about the Teledyne Continental "Super M60" program, I have never heard of the "General Dynamics High Performance M60 MBT project."  General Dynamics had zero interest in upgrading the M60 and really disliked the fact that Teledyne Continental had created the Super-60 because it was considered unwelcome competition to General Dynamics Abrams tank in the time period addressed in the book.

 

Anyhow, the AVCR-1790 took the variable compression ratio technology developed for the ill fated AVCR-1360 engine of the MBT-70 and General Motors rejected XM-1 prototype and applied it to the older AVDS-1790 engine of the M60 series.  The introduction of VCR to the 1790 got the engine up to 1200 HP, although from what I understand, the prototype suffered a pretty serious failure during testing in South Korea.  Teledyne abandoned the AVCR-1790, replacing it with the AVDS-1790-9, which achieved 1200HP by introducing aftercoolers to the turbochargers with conventional pistons.  Incidentally, Teledyne Continental promotional materials for the Super M60 list either engine, depending on what date they were published.  The AVDS-1790-9 would go on to see service in the Israeli Merkava III and the Namer APC.

It does say this was published 1989, so the info might not have been available at that time?

It was, they just made some mistakes.  The Teledyne Continental engine nomenclature was widely known at that point.  Heck, the basic AVDS-1790 went into service in 1960.  Hunnicutt's book on the Patton series of tanks was published in 1984, so they really don't have an excuse.

      Found a few higher resolution photographs from the recent North Korean military parade. We didn't have a topic for BEST KOREAN armored fighting vehicles, so here it is.
       
      New main battle tank, Abrams-Armata clone based on Ch'ŏnma turret design (welded, box-shaped turret) and Sŏn'gun hull design (i.e. centerline driver's position). The bolts of the armor on the hull front is finally visible given the increased resolution. It might not be ERA given the lack of lines inbetween. Maybe is a NERA module akin to the MEXAS hull add-on armor for the Leopard 2A5?
       
      Other details include an APS with four radar panels (the side-mounted radar panels look a lot different - and a lot more real - than the ones mounted at the turret corners) and twelve countermeasures in four banks (two banks à three launchers each at the turret front, two banks à three launchers on the left and right side of the turret). Thermal imagers for gunner and commander, meteorological mast, two laser warning receivers, 115 mm smoothbore gun without thermal sleeve but with muzze reference system, 30 mm grenade launcher on the turret, six smoke grenade dischargers (three at each turret rear corner)
       


       
      IMO the layout of the roof-mounted ERA is really odd. Either the armor array covering the left turret cheek is significantly thinner than the armor on the right turret cheek or the roof-mounted ERA overlaps with the armor.
       


      The first ERA/armor element of the skirt is connected by hinges and can probably swivel to allow better access to the track. There is a cut-out in the slat armor for the engine exhaust. Also note the actual turret ring - very small diameter compared to the outer dimensions of the turret.
       
      Stryker MGS copy with D-30 field gun clone and mid engine:

      Note there are four crew hatches. Driver (on the left front of the vehicle), commander (on the right front of the vehicle, seat is placed a bit further back), gunner (left side of the gun's overhead mount, next to the gunner's sight) and unknown crew member (right side of gun's overhead mount with 30 mm automatic grenade launcher mounted at the hatch). The vehicle also has a thermal imager and laser rangefinder (gunner's sight is identical to the new tank), but no independent optic for the commander. It also has the same meteorological mast and laser warner receivers as the new MBT.
       
      What is the purpose of the fourth crew member? He cannot realistically load the gun...
       
      The vehicle has a small trim vane for swimming, the side armor is made of very thin spaced steel that is bend on multiple spots, so it clearly is not ceramic armor as fitted to the actual Stryker.

       
      The tank destroyer variant of the same Stryker MGS copy fitted with a Bulsae-3 ATGM launcher.
       

      Note that there is again a third hatch with 30 mm automatic grenade launcher behind the commander's position. Laser warning receivers and trime vane are again stand-out features. The sighting complex for the Bulsae-3 ATGMs is different with a large circular optic (fitted with cover) probably being a thermal imager and two smaller lenses visible on the very right (as seen from the vehicle's point of view) probably containing a day sight and parts of the guidance system.
       

      Non line-of-sight ATGM carrier based on the 6x6 local variant of the BTR, again fitted with laser warning receivers and a trim vane. There are only two hatches and two windows, but there is a three men crew inside.
       
       
      There are a lot more photos here, but most of them are infantry of missile system (MLRS' and ICBMs).
