I've a VXR8 this week, it's a rocketship. I can't imagine what the HRT 427 is like.

The VXR8 does however have the predictable problem:


Lucky fker, mine is sat at 14.4 mpg...

Hardly. This is the motor from the real HRT 427, a genuine 427 C5R. In two guises - with and without roadgoing air cleaners.





I'm not sure how many of the HRT's original bepoke parts are present on this one, which a Cairns based nutcase paid $920,000 for in 2007. Now someone clearly feels they are legitamately owed 8 years interest on that sum.

That motor now looks like a dirty near stock item. Pretty sure thats either an LS2 or 3 intake, definitely not LS7. There will be little power to be found there with that strangulation on 7 litres NA. If it is a 4.125 bore 427. It could easily be an LS2 with a 4.1" crank in it now.
I seem to remember that the 427 lost the C5R and went to a bored/stroked LS motor during its development. The ad mentions that this car was road registered, maybe Holden couldn't get the throttle bodies to pass rego?

If you want an Australian automotive investment, buy a VE or VF SS or Maloo ute or one of the Ford utes from the last 5 years. They are good cars that meet their design brief well but more importantly, they are still held aloft as a holy grail by a big section of population (any red-blooded male between 10 and 40 or tradie) and they will soon cease production.

Sadly they could not compete with the practicality, economy and quality from the march of the Japanese dual cab 4x4. Ford Aus and Holden were a token presence in a tiny market for the parent company. Progressive thinking and innovation were not high in their culture or design language (innovation is expensive with little chance of a payback in a small market) and you cant build cars in Australia anymore and compete economically with Japan, Korea etc. I find it a great shame but in a business sense, they both got exactly what they deserve.

It looks an awful lot like an LS1 to me.

LS1 style intake manifold (more pronounced / defined intake runners than the LS2 and LS3, the LS7 had a squarer style)

Cable throttle body. Would need to have gone to a custom ECU/OS to support this which seems like a lot of work for something they've bodged in instead of ITBs

LS1 style coil packs (different shape completely to the later LS coilpacks)

To have these 'cheapo' items, then spending the money re-sleeving it to support a 4.125" stroke without consuming oil, and boring it out to 4.060" to get your 427ci, it seems a little odd...

I'm betting they just chucked an LS1 in this one hehe

Sorry, but the only truly collectable car is the GTHO. 300 built, and today only about 1500 left...

Wow, how did they increase in number?! Did they breed?
