Re: Pressurized center main bearing?
That passage is just a dribble feed-gravity flow from the valve chamber. Mains are starved for oil until oil warms up on a cold day. The center main is stressed the most, so needs the most oil. ...

Re: 59 352/4 carb
With vacuum operated secondaries the rears do not open until the engine needs the extra airflow (maybe above 4,000 RPM) so off the line your 4 barrel carb is functioning just like a two barrel carb....

Re: 10" Ford Tractor pressure plate
It will have stronger springs to overcome the lack of weights. The tractor engine only revved to maybe 12-1500 RPM so not enough for the centrifugal effect. So you will likely have a stiffer pedal...
