Finally found one of these hen's teeth intake manifold. Now that I have it in hand, I put it next to my 04 truck manifold and see there are a few small differences between the 87mm TB version of truck manifold and the 04 truck manifold, such as which vacuum ports are plugged and which are open, and the location and style of the Evap purge sol'n & the MAP sensor. I'm considering running this so I can keep my Flexfuel rail with return line and not have to contend with the other ways to make it work on the later TBSS/NNBS intake manifold. Here is a picture of the hen's teeth manifold for TonyRodz.
Sorry for the hijack m1949. This was the only place we discussed this manifold.
