I sure would have liked to compare that setup with my blue thunder and eldebrock when I dynoed my yblock. I've got to wonder what it would've done.

Hey wait, what am I saying, I just remebered I've already broke the bank anyway!

see "Dyno results" in Street Forum.

  In case you haven't seen them if you look on the vintage speed site they have the holly 94's there, as well as the  single parts to repair what you have.  looks like a nice web site, they also have alot of 3 two setups..  And I have an old fenton manifold with the holly 94 set-up    f-100 bob

Y,

      Not supposed to be extremely loose, no. It does need to have some small amount of clearance to allow for various thicknesses of thermostats and gaskets. As long as the thing can't leak an excessive amount of water past it it's probably OK. The depths and diameters were determined by measuring an original housing and about ten different thermostats. the Thermostats and the housings all were different. This is obviously one of the problems of "reverse engineering".
