help on identifying intake manifold
 

911 intake manifolds with # 901 108321. would appreciate it if someone can indentify these or tell me how to source ID numbers to figure it out myself. thanks Henry

pic?

Henry,

They should also have a date mark on them.

I have around 8 pairs being chemically stripped at the moment and as soon as they come back I will list the numbers and dates - should be back with me in 2-3 days.

Thanks chris, I'll look for the post. the ones I posted about are 35 mm and don't appear to be bored. early Ss and Ls then Ts before 73.5 all had intakes manifolds and I would assume they would be same size as the heads on the various cars, which varied from 30 mm to 36mm IIRC. best Henry
