Mick, GMH have a surplus engine sell out. The offer is available from several holden retailers.
Here is a link to Holmart offering the same deal on the Oz Ls1 site.

Sounds like a great deal.

Although this shoot out was based on an LS2 block ( not unlike the L76) it shows the potential of this combo.
