Was that video about oil levels, or oil pumps?
yep
this isn't really for you, I know you know
it was
Oil levels in a custom pan... too much kills power
it wasn't really about the pump, it was a BBC too
still does the same thing
(as you probably already know also)
a BBM HV Mellings oil pump is the way to go,
on almost any BBM
(you will need slightly longer bolts, to bolt it to the engine, that don't come
with the HV oil pump, ARP has kits, so does
440 Source.com Homepage )
& don't overfill the oil pan/capacity, even on a 5qt system
is what they are saying
keep the oil under the windage tray
so the crank isn't aerating the oil
(or causing oil to foam & loss of oil pressure control)
so it also has a place to drain back
&/or the oil (too full) actually the crank hitting the oil
for those that don't "actually" know or "are new to this stuff"
for a mild street-performance use the BBM 6 qt pan & oil pickup
comes in either 3/8" (like 383-400) or 1/2" pickup, like a Hemi pan
specifically for a B-Body
if you have the room to fit it, is a decent & inexpensive way to go
Or if you're not spinning it over 5,000 RPM regularly
you can use the OE pan, no harm no foul
test to see where the oil level is
you can do it on a table, pan off the engine
set the windage tray in it, fill till it is just below the windage tray
check or measure/by volume how many qts it takes
you can watch the full episodes on MT
generally a good rule of thumb
is 1 qt volume for every 1,000 RPM the engine will be spinning
a proper custom or deep pan, with a windage tray &/or a scrapper too
is worth it's weight in gold
if properly filled
again you probably already knew that too
Engine Masters did an episode on BBM Oil Pans/windage trays
& which Oil Pump was best too (HV)
