They did have V8 WB commercials, and the 4.2L V8 offered was far closer to the 5.0L in performance than the old red 4.2L. Remember on a commercial they were single exhaust only. Single exhaust figures for them are:
HZ 4.2L - 87kW@4000, 271Nm@2000
WB 4.2L - 100kW@4200, 269Nm@2000
WB 5.0L - 117kW@4000, 336Nm@3000
Plus the XT5 3.3L in a WB was a far better performing engine than the red 3.3 in a HZ. I drove both, my dad had a WB 3.3 4spd 3.36 van new, I used to drive it all the time. Plus I bought a 12/84 WB 4.2 4spd 3.55 cab-chassis when it was about 4 years old and still stock as a rock. The van probably had almost as much more go as the tonner which was lighter and lower geared.
Sure 1 in 100 buyers might have wanted to order a 308 in a WB, but most would be happy with the 3.3L, and the remainder with the 4.2L. Just look at it today, there is a market for a decent engine in today's equivalent of the WB ute - the dual cab 4x4. But it is a small market. Everyone wants the "173-202" version (the tiny little turbo diesels). There was a "253" version available but only those without blinkers on bought V6 petrol Hiluxes and Navaras, so even Toyota eventually stopped making them. In comparative terms I'd be the one knocking on the caryard's door asking for the good engine in the ute, just like i'd have been trying to buy a 308 WB ute or 350 HQ ute. I asked the same question of Nissan when they released the 5.6L V8 Patrol, I wanted to buy the Patrol ute with that engine and auto transmission rather than the awful 3.0LTD in them. I'd also put up with the awful comfort in a '79 Series if Toyota put the "308" version of the petrol V8 in it (5.7L V8 is the big "308" version of the 4.6L "253" V8 as found in 200 Series). But it isn't worth it for them as only a few % of people would buy it, most are happy with the tractor engines. I don't think the logic today is any different to WB era. GMH could have offered the 5.0L as auto only in WB commercials with no major cost impact to their profitability, but having a manual one available would have meant another engine to build and a very low volume one at that. Remember GMH were treading water to keep afloat at the time and anything decision wise that wasn't a show-stopper return probably got knocked on the head. Looking back GMH could easily have offered the 350 on HQ commercials, and built a few SVO examples of those too, however then the same decision was made as for WB - not worth the hassle as the single exhaust HQ 308 wasn't far off the single exhaust HQ 350 in performance, probably as close as the blue 4.2L was to the blue 5.0L.
The other L31 WB Kingwood ute I mentioned is a 1983 model, built 9/82. It is Alabaster White. It has a T in its VIN plate. The VIN on the broadcast sheet has the L crossed out too with a T written over it when the SVO was applied. I don't have a VIN plate for the Manifest Orange cab-chassis, but it is an earlier car as it has an M38 transmission (I thought this was M40 but it isn't meaning the Malachite one is probably the 2nd column shift TH350 Holden I've seen, as I assume this cab-chassis would be column shift not console shift (don't have an ADR plate for it)), it is earlier than the Malachite ute probably 6/81.
