      Hey Mike, while your at it: you should drill 4 more holes in that restricter plate. Word is that got 48 Thou into that thing, I wouldn't take any chances. Oh yeah, that is the purityist looking 3/8 sq hole I've seen in a looong time! LOL

        Here's a page Clair put together a few years ago comparing the flow openings.
        340 Right Angle Oil Filter Adapter

        But for this build I wouldn't worry too much about the openings. Chamfer and smooth what is convenient and put it together.
        The thing that is worth worrying about is getting the clocking so filter and be removed and installed the most easily.

          so the new housing and the 20% greater flowing old bolt? Sheesh! I tell you with my 90 adapter and Hooker Super Comps in my 65 A, I still could barely get the oil filter out, and that was juggling it with oil dripping all over the place. I could have went with a smaller filter (smart) or use a filter relocation up onto the fenderwell and never F with that stupid oil filter inside the headers...I did the latter. A good filter with an anti-drainback valve.

              Mike,
              If you are interested in selling your old oil filter adapter, I will buy it from you.
              Picked up a spare engine the other day and it is missing.

              It is interesting the aluminium p-part adapters came with an apparently more restrictive hollow bolt since the target market would include racers taking thier engines to 6000 rpm and more. I suspect it doesn't signifcantly affect flow, and just like everyone else who gets into looking at the passages, I figured why take a chance. LOL. I used an original cast iron adapter and chamfered and smoothed everything.

              If you want to see yet another interesting adapter bolt/nipple, look at the ones for marine engines and some slant sixes too. They have spring loaded check valves. I'm sure that's restrictive too. But in my limited experimentation with one, it didn't noticibly impact pressure (and therefore presumbably flow).

                Mike - you may find an o-ring on the nip for the plate adapter when you take it off. I didn't rember that, I don't recall if its used with a right angle adapter.
                Here's a pic of some long tube check valve equiped ones. The one on the right is for a slant. One of the others, I think the middle, is for marine v-8.
