difference between a 3310 and 4779 primary metering blocks.
I would think they would be interchangeable, but my research says otherwise. What's the diff? The venturi sizes are the same.
So much to do, so little time...

I have used them on both the 3310 and 4779 and interchange them all the time with no problems. The sec ventui's on the early 3310's are bigger until the -4 or -5 then they measured the same.

I can’t verify it but I believe that the PVRCs are larger on the vacuum secondary models over the DPs I’m sure I read it in a book long ago.

Thread both the idle feeds and PVCR's and it won't matter.
