Back during my build when I realized I needed a choke ring I didn’t think I could find one so I drew one up and was ready to have a buddy CNC it, but common sense prevailed, and I called McLeod , they said yup , we have the one you need!
Here is the pic with caliper on it measuring 4.8480. blykins is exactly right, it’s a small interference fit nice and snug. I custom made washers used beneath the 4 mounting bolts to hold the choke ring in place. I could have glued it in with lock-tite but didn’t. My setup has a McLeod bolt on HTOB and thus I removed the Tremec bearing retainer which was handy for answering your question

Awesome!!! thank you very much. It will be the silver ring that Quicktime supplies.
That crazy diameter isn't listed anywhere on the internet, :-(
Now I'm waiting to hear back from the Holley tech gurus for the type of fit the ring should have with my BH opening.
