Hi all,

I recently acquired a Weiand head, I have always wanted one but they never seem to come up for sale. Does anybody have any info on these? There is literally no info out there regarding this head. I have read on the HAMB that they were supposedly 7:1 but that is about all I can find. Anybody have anything else they can share regarding this head? When were they made, etc. any help appreciated.
