That's one of my ...why's...the oil filter just goes into the block.
It's not even in series..to complete a circuit..

With the exception of the prewar seniors with full-flow, that type of filtration was pretty much standard industry practice at that time, though nearly universal full-flow was just around the corner.
No sure what you mean, in my view it does complete as circuit, the oil pump starts the loop by drawing from the sump and the filter ends it by returning the oil to the sump.

In the early straight 8 filters there was an orifice in one of the input fittings to lower the flow volume thru the filter to keep pressure in the rest of the system. Originally with the first filters at the filter itself but later on in the 4 way fitting. I believe that orifice may have been eliminated in favor of some very small openings in the filter center pipe to provide the same function. It might be interesting to know the flow rate of the S8 filters vs the V8.
I wouldn't think there would be any issue adding an orifice to the V8 fitting as an experiment. If the center holes are doing their job the flow would still be restricted to what was originally allowed and there would be no change in pressure. if there was excess flow before, the orifice might reduce flow thru the filter a bit but make it no worse than the earlier engines and certainly better than no filter at all.

Sorry guys, didn't mean to bring up the partial filtration bypass: every forum on every vehicle made in the fifties worldwide grinds through the same should have/ shouldn't have
- anyways, I do like the olds pump conversion - for peace of mind especially as you know you're going to have no lifter rattle and good pressure at idle etc. It's a good feeling "Are you sure you mean fourty-five thousandths, not four and a half thousandths wear on the mains?" Yep - the crank was toasted. I took a photo of one of the mains and it's about as bad as a crank could get I'm really pleased to hear about your car being so good. As I'd kind of mentioned earlier - I'm sure that if the car has been well treated, oil changes, good oils in the past etc they can and will live. I feel a bit like, as with most modern cars marginal cooling systems, it takes very little, in this case grubby and solid oil, to turn an adequate oiling system into an inadequate and potentially disastrous one. Isn't it a gorgeous day, especially when it was meant to rain

Dave..
In general terms.. Yes..starts and ends. But... In an electric circuit..that would be open..unless you used a switch.. From what I get..is that oil line goes into block. Oils timing chain. I guess the only way is to do what Kevin owns one did.. Tie into suction side of oil pump..

I don't think the filter return does much for the chain directly since filters were an option and not on all engines. I believe the return drops into the lifter valley and while there may be an opening into the chain cavity, if any gets to the chain it is incidental. The chain is oiled by the intermittent squirt from the cam uncovering the hole in the thrust plate every revolution.

LOL that's brilliant - and I never clicked the word "munted" was a geographically specific colloquialism.
