How many 3000M big valve?

[valve]

Hi,

I remember reading in an old sprint about 3000M cars with factory big valve conversions, (I still have the sprint magazine but it is stored with other belongings in Sweden).

Do anyone know if the story is true? was there factory tuned 3000M's delivered and how many where made?

I think from what I remember from the sprint article that the conversion made ws similar to Ford original X-pack conversion using a Wd=ber 40DFI carb an bigger valves on a otherwise almost standard engine.

Regards Hans
