Is this engine block a direct replacement

[Kimba100]

Hi Guys

Can someone tell me if the Alloy block talked about will bolt straight into my VR v6 Commodore Please?

Series 1 (Same as your Series 1)
Series 2 (Holden modified V6 based on the Series 1.)

They say it will bolt up to any GMH gearbox, and take standard access.

I would contact them if I could.

Dose anyone know if this has been done before?

If anyone can shed some light on this it would be much appreciated.

Thanks
