Reply to "roush motorsport single palne intake"

I sold that manifold and agree that the important part of the number was stamped.

It doesn't seem to be important now but I thought I remembered it as being stamped 341.

That one is in the "parts catalog". I have not looked at it in awhile.

I thought it was that the 331 was the torker and the 341 was the spider for the B351 heads? I suppose it is academic at this point anyway.

Since George didn't post the "tiny" port 331 picture I'll see if I can post it here. The ports are way smaller the the B302 ports. Closer to a 289-302, 2v style port. It seems very obvious that it was intended to be match ported to whatever you had.

However if you look at it the runners and the plenum were much smaller height wise then the 331.

Can't find them, maybe later?
