More Fully 6, Bathurst, Bathurst plus and YellaTerra road racers are underway with a bunch machined up for changeover heads

We are still receiving a large call for the trusty Holden 6 head which is just awesome to see.
Don't forget we offer the Fully 6 formula for all types of Aussie 6s whether it be Ford or Chrysler..

We hope to be streamlining the ordering system of these heads with a step by step checklist so these heads are tailored to your specific combination.

Please don't hesitate to place your order if you are thinking of giving the old girl a bit of a birthday or trying to find that little bit more horsepower.

Finally after collecting all the parts and making so many custom 1 off parts this blown Irving is ready to be fitted to the car...

We were asked to make this very unique creature with absolutely no power figures in mind it was purely I want a blown Irving, I want it out the bonnet and here's the Weiand blower from Aussiespeed.
I think we got that covered.... Don't know how much EH bonnet will be left though.
So we opted for a mild solid cam, mild compression, no porting, nothing too over the top just a reliable strong engine.

We ran the engine in NA just to make sure it was right before fitment even with the blower spec cam and only 8.5:1 it just had that sweet unique Irving raspiness. We can only imagine how ace this will sound with the blower going.

There will be some more Irving content coming as we dyno this car and still finish off my HQ test mule which is not far away.

Well there's no time like the present. There has been a bit of a shakeup here at HSD after 30 odd years in Capella crescent and over 40 years in the Moorabbin area we will be heading to Carrum Downs... There is no definite timeline as of yet but aiming to be operating in the new premises in August.

Also Pat has decided that after a long 27 years to go out on his own, he will be taking the CNC lathe producing valves and guides for us still, obviously adjusting to the change Rodney and my work loads have taken a bit of a hit as we are trying to still do the work of 4 people since Ed's retirement.

Thank you all for your patience and understanding that there's a fair bit going on so phone calls and emails have been a bit slow to reply too.
We are still operating and still taking on cylinder head jobs but engines will slow till in the new premises

Onwards and upwards.
