I've found the semi-open spacer to work the best, divided between the primaries and open or notched between the secondaries....Cliff

   The spacer is in the book by Jim Hand, (Pontiac performance book). Wish I had a pic handy but the spacer is fairly "hand made" (pun intended). Wat it does is separate the primaries for the most part but leaves the secondaries to communicate with each other (open). Imagine if you had a spacer that was 4 hole and matched the bores of a Q-jet. If you took and carved out the material between the secondaries bores of the spacer and then rounded off the part that would transfer into the primaries but basically leave it separate the primaries. that is kind of the idea (if you can picture it). I think in the book he shows you how to make one out of wood.  I guess a notch between the secondaries would do the same thing.

Jim Hand spent more time at the track testing spacers than anyone else that I know of.  Decades later, when I did the same sort of testing, guess what?  I found that a spacer based on his "semi-open" design ran the best compared to any other.  This was on a dual plane intake, open single plane intakes work best with fully open spacers.....Cliff

Do you know where you can get the book?Thanks for your help Steve

Not exactly, also remove the material between the front and rear holes, but leave it intact between the primaries.

The end result should pretty much match the opening in the aluminum intake on the left....Cliff
