buick/holden v6 ,3800

[David Ford]

Howdy all,
          Does anyone know the difference between the australain holden
commodore v6 3.8 L and the  buick v6 3.8 L supposedly holden australia spent
over 1 mill on adapting it to "australian conditions",??
And secondly does anyone know whats involved in converting the throtle
body,computer,etc,etc..... to being suitable for a v8 i.e. the rover/buick
3500,?
Thirdly if this is a totally stupid idea (I believe they run on maf
map's,maybe dull down fuel pressure or something??) does anyone have any
idea's on a conversion possible for the 3500,australian parts prefered
:-),from carbie to fi,
Cheers all,
        Dave,?
