The recent resurgence of interest in older model Holden Commodores has seen a
corresponding attraction to the rarer and more exotic models.
Its not uncommon, for
instance, to find a genuine Brock SS Group A VK selling privately for $30K, but
enthusiasts are equally interested in HDT-equipped VBs, VCs and numerous other pre-VL
specials and rarities.
There are also a number of not-so-common early model HSVs out there too, and that all
of these cars will attract higher and higher prices as time goes by is an accepted fact.
Wayne Robeson of Perth is certainly no stranger to exotic and historically significant
Commodores. After owning one of only 48 VK Group A / Group IIIs ever made and an SV 3800,
Wayne decided he wanted something of an even earlier vintage.
But we should probably point out here, that Wayne didnt just want a Classic
Commodore for Sunday cruisin and posin.
Wanted full metal fun car
After becoming involved in Perths HDT / HSV Owners Club, Wayne quickly found
himself using the family VS Clubsport for driving and sports events.
Not a very convenient situation as it turned out; "After a day at Barbagallo
Raceway or a hill climb, Id have to spend all of Sunday night changing brake pads
and wheels on the Clubsport so that my wife could have the car for Monday morning!"
A car specifically for sporting
events was obviously required, and there was good reason too for choosing an earlier model
Commodore.
"Theyre lighter than the later models for one thing and theres just
something about those early Commodores," said Wayne.
Perhaps the term metal not plastic can be applied here, but whatever, Wayne
seems to be a magnet for those exotic Commodores. The VH he acquired isnt just an
ordinary Group 3, but one of the high output options.
Nobody seems to remember exactly how much the high output option produced, but
its a little irrelevant now anyway, as this VH at least has a fully rebuilt
naturally aspirated 308 that produces 310 horsepower at the back wheels.
Some serious suspension study
Well come back to the engine in a moment, because BRE Performance in Perth first set
about giving Waynes car the suspension it needed to actually use the extra power.
The set up is very much based on what Commodore Cup Cars run. In addition to Kings
springs and Bilstein shocks at both ends, this VH has been equipped with custom built
height adjustable struts, an engine bay strut brace, Whiteline adjustable sway bars front
and rear plus a K/mac castor Camber kit up front.
More than enough to keep any club racer fiddling for hours !
Brakes to match are 330mm rotors gripped by Brembo four-spot calipers that used to live
on a Porsche. The calipers sure look the part behind those17" VS Clubsport rims,
although the raised Brembo lettering had to be ground off to allow at least 1.5mm of
clearance to the rims !!
With suspension and braking equipment of the highest order, Waynes VH was ready
for a fully bombed 311ci V8 under the bonnet.
More than one way to measure `quick
Now, with a best time on the quarter of 12.715 @104.52 mph, you might think that
theres room for improvement with this VH as there are certainly Commodores out there
doing quicker times.
Yet it should not be forgotten that
this one is using a naturally aspirated motor with no blower, no stroker crankshaft - and
no nitrous bottle in the boot either.
That 12.715 was also achieved on shiny street tyres, so theres a few tenths lost
in that area for sure.
It also needs to be said that while ¼ mile times are regarded by many as the only way
to judge a cars performance, times around an actual race circuit are just as good an
indicator.
The long circuit at Barbagallo Raceway has become something of a benchmark in its own
right for WA modified car owners and the Western Australian HDT / HSV Club record is 65.23
seconds - held by Darryl Abbott in a radically modified VR GTS
Waynes best lap is 70.30 seconds, which we dont think is too bad for an
old VH by comparison !
Back to Waynes engine though. While the full details of the rebuild can be read
in the Nuts`nBolts, no short cuts have been taken and the amount of preparation work
is amazing to say the least.
In summary, the capacity of the original 308 is out to 311ci, while the bottom end is
fully balanced and a Crane roller cam runs up the Vee.
HSV GTS VR heads have been used, fully ported and ccd by Ron Harris and then
filled with all the exotic valve gear that could be found.
Induction is achieved through a Holley 750 spread bore carbie and a port matched Harrop
single plane hi-rise manifold.
The free flowing exhaust system begins with Genie 1 ¾" primaries, followed by a
twin 2 ½" mandrel system before a 3 ½" merged collector and, eventually, a 3
½" muffler.
BREs Shane Carson built the exhaust system and says it took three full days to
complete !
Original interior, stronger cog-swapper sought!
You might think that with
an engine this good, the gearbox in Waynes VH would be equally impressive. But while
theres a 10.5" Chev clutch and Yella Terra lightened steel flywheel on
board, the gearbox is a stocker.
Wayne admits that its the one area with his car that needs addressing and
hes hoping to have it sorted before something nasty happens!
On the cosmetic front meanwhile, and it might come as something of a surprise to learn
that this VH Group 3 is still wearing its original Milano red paintwork.
"I have done a few touch ups and theres one or two pin marks," conceded
Wayne, "but its been polished and buffed and in remarkable condition for its
age."
Its worth pointing out too that the cars original wind splitters are still
attached to the bonnet.
These wind splitters were supposed to direct air flow over the car in such a way as to
help force the car down onto the road, but just as with the polariser, well leave
the debating to another time!
Its still interesting to see this VH wearing its splitters however, as they had a
tendency to simply drop off.
Also in remarkable condition is the cabin of this classic and while Wayne has added an
Autometer shift light, Sparco pedals and harness, a roll cage (now legal in WA -
hooraay!!), and race seats are going in real soon.
In fact, having come this
far, theres no turning back now and Wayne has a full list of future upgrades to help
make the car go faster and harder.
The priority though is a decent cog swapper; "Ive got to get a T5 or a Temec
in there .... how long the original gearbox is going to last I dont honestly
know!", he said.
