I disagree. They float a bit over 180 but they aren’t that bad. My WRX STI was definitely better though.

Where were the roads good enough in Australia to drive a hZ holden at 180k's? I drove a hz for 8 years I lived in the Territory when there was open speed limit . Keep the bullshit coming I've lost my licenece for speeding plenty of times.
How long did you stay at 180k? 30 seconds ? Where can you drive a HZ at 180 what was the accuracy of the speedo past 150?
Why doi Holden men allways bullshit?

When a HZ speedo read 180km how fast were you really going? The few I played with were 30 k's out by the time they read 180, one read 180 but the reality was it was doing about 150. The car had the orginal ratio diff the speedo was pretty close until about 120 k's.

I had a recalibrated speedo which was within 2% on the dyno.
what was the accuracy at 180 k's ?

The guy that built the speedo with a new face (220 km/h), bench tested it & said it was was good within 3.5% at full scale.

The dyno only when to around 135 km/h. So 2% at that speed verifies that.

Try all the way from Bundaberg to Brisbane and back hundreds of times dude just taking it easy and at night many a time, she had spotlights dude. that's not even getting into it.
She had 3.08 diff 235/60 x14 tyres and sat on 4500rpm at 180KM/H Back in the 1980's you are not sitting on 180 all the way but just float up to that crusing speed easy as, not pussing it at all.
Oh i always had a radar detector. still got busted tho at times.

I had a XG Longreach ute and a mate drove it on the double lanes all the way to Brisbane at 210KM/H and it was cutting out at 210 found out that it was speed limited, the Ford dealership did not even know they were. then when the ED Falcon came out they were speed limited to 180KM/H
a mate bought a 1994 Longreach and he was spewing that it was limited to 180 because every morning to get to work he drove at 210KM/H In his XC 5.8L. We had a run with my XG and his XC and he went out directly and bought a New XG, because he was so impressed !

I road on the double lanes out and to Brisbane at 240KM/H taking it easy dude not pushing it at all, just playing it safe ! if a car pulled out into the right lane you just back off touch the brakes, you have washed off the speed easy as and then just back to 4th 5th then 6th in no time. Look the 1/4 in 9 sec dude and a quiet bike stock as a rock.
No one can do what i did unless you get your eye in ? and know your car or bike real well. I would never drive something that i did not own like that, you have to work out your tyre pressures etc you have to know what you are doing. the average dude would be dead in no time because they do not have a clue, if you think you are pushing yourself then you are going too fast dude !

I rode Enduro bikes as well and dude that's a way to challange yourself hooking in full on !

But i am in my 60's now and retired, i have no need to hook in and i would not do such because i am not that fit etc to bother with such.

Dr Terry,
I know I’m a bit late to the party but I thought I’d jump in.
My (Dad’s originally) VH Vacationer 4.2 has Nov 83 stamped on the info plate. He bought it from Ron Hodgson’s in June 84 after looking at the VK’s earlier and not liking the look of them, plus they didn’t have the 4.2 and he had a caravan trip planned. They had two left, 1 of the ?gold? and 1 of the blue. He liked the Pacific Blue much better and grabbed that one.

So, they were built into Nov 1983. I assume to finish off the 4.2 in Commodore, and to have stock until the VK took off.

Model VH8VK69
Body No 111820 - A
Trim 3042 - 23X
Paint 2B 035-D
Built NOV 83
Eng L36 Trans M40 Axle GU7

When I got the car I sent the details to Holden and their reply was it is a VK…
It isn’t.

Yeah thanks for that info.

I was talking to the VH Vacationer batches specifically. The suggestion I thought was that they were done in batches in 81, 82, and Oct 83. But at least some were built in Nov 83.

I wondered, or assumed maybe, that the Oct 83 may have been the 3.3 and maybe the Nov 83 batch was for the departing 4.2. Maybe to clear the Commodore edition Blue 4.2?
Were the VH & WB 4.2’s coded differently?

There would be no reason to “clear” 4.2 engines. There would be one engine manufactured for every car scheduled. If something happened and they were one engine short they’d simply build another one for the car.

The January 1984 car I mentioned is an L36 M40 and there will be plenty more. Note that as Dr Terry says the WB and VH engines are very different. But auto and manual are different engines too. Manuals come to the VAP’s with clutch and bellhousing, plus the dizzy is different, and the manuals have no EGR valve on them, the location is blanked off. So at that time there was at least 4 x L36 engines.
