if i had to take a guess i would say that holden brought out more,with the buick v6.
but here`s a good question for you all. what company made the vn v8`s?
They are all holdens with different badges & trim.
VNV8 is a holden produced engine, based on the original 5.0 which was based on an old Buick V8 (early sixties)
did you know that the orignal motors that was going to to put into the vn`s was the vl turboed motor.
and also that the first of the buick v6`s was carby driven.and they some times also run them in the odl daytona cars
