175CD2 carb and manifold

[JeffreyLos@aol.com]

<As promised, here are the part numbers cast into the
ZS manifolds I have:

large port: V3178
small port: V3796

Thes numbers are cast into the bottom rear of the
plenum, and can be hard to see when installed.>

With the above information I can now report that the 175 on my 72 Spit has 
the V3178 large bore manifold. You can easily check your manifold to see the 
number using  a small mirror (or in my case a small piece of bright chrome) 
on the bottom left side.
