I have always wanted to put two red sixes together too create a Red V12,
it would be called a XU4 as a XU1 is a 6 cylinder and a XU2 is an 8 and a XU3 would be a 10 so a XU4 would be a 12 Cylinder.
This would fit in the LC / LJ Torana and would be a lot of fun.
Tilting the red six so the cam is at the centre of the ''V'' the other half can use the cam.
There would be the case of recreating the Block, but all parts would be the same after that.
I have seen the almost use of the Holden prototype V12 using two V6's, but to no avail in the Prototype Car.
Any thoughts anybody on the Holden V12 ideas. Dave I
