Ok guys, I thought I would pick the brains of the 911 6 engine experts. (I posted this also on the 911 Bird board).
I'm trying to figure out what I have here. I bought these a few years back with some Weber's and they are not like the other manifolds that I have. As you can see there is no provision for the cross bar linkage and theye are taller then the stock manifolds. The top (carb) ports are 45.5mm and the bottom (intake) ports are 38mm. The part number on them is 901.108.318.00, I've searched for this part number and haven't found anything.
Anybody seen these or know anything about them?
Thanks
Paul
