It can, and has. A stock hemi could pump a stock pan dry at drag racing revs, in 10 seconds. Tom Hoover pointed that out to me.Sorry to hijack but Im sure I've read a HV pump can suck a standard sized pam dry?

The symptom is there, but the cause is not the pump, the pump pumps exactly what the engine demands to maintain oil pressure set by the relief. The engine demandSorry to hijack but Im sure I've read a HV pump can suck a standard sized pam dry?
The symptom is there, but the cause is not the pump, the pump pumps exactly what the engine demands to maintain oil pressure set by the relief. The engine demand
doesn't change because You bolted a HV pump to it. BUT, if the pump has too much excess capacity, it will bypass a lot more oil thru & back to the sump. This can result
in too much aeration and contribute to increased oil wrapped up in windage around the crank. Poor drain-back can plague other brands as oil gets trapped in the heads and
valley, but that is not one of Mopars weaknesses.
"A pump will pump what the engine demands" ? LOL A pump will pump what it`s going to pump, no matter what the engine needs, one way or another !I still would like to see a picture, of his knowledge of crankcase ventilation.,It's that damn simplistic.

Indeed you have, but it's a myth.
Recently - I noticed smoke out of the exhaust. I've also noticed dirty plugs and an oil film inside my new exhaust pipes.

That would be true if the pump had no relief valve.
Not to hijack this thread Rusty...but how is little Pooter doing? Got any new pictures????
You might lightly snug the pump bolts then drop in the intergear then torque the pump bolts. this'll give a better hex alignment. it is a good plan to in addition install the dist & its clamp to lock in the intergear in case you forget that the intergear can drop out & hit the floor if you flip the eng to tighten the pump bolts. I hate stupid mistakes.That's a possibility, I believed I was in all the way because the rod was actually a ***** to get out, but i could be wrong! Gonna tap it down gently with hammer handle this time to be sure.
No, a pump delivers the volume needed to reach the pressure the relief valve is set at, after that it bypasses....it's that simple. If putting a higher volume pump increases"A pump will pump what the engine demands" ? LOL A pump will pump what it`s going to pump, no matter what the engine needs, one way or another !
Could have good compression, and bad oil rings, so it runs good but smokes. Could also have intake and head mismatch, sucking oil from the valley.

I agree w/ this post, but the hemi has return holes for the oil going back to the pan, along w/ overflow around the intake runners and pushrod openings. the 440 has only the overflow around the pushrod openings .No, a pump delivers the volume needed to reach the pressure the relief valve is set at, after that it bypasses....it's that simple. If putting a higher volume pump increases
the volume actually used, it means the stock or previous pump was inadequate for the engines demand, if the result is an empty oil pan...You have either poor return, too
much windage, or the pan is too small for the job. The engine may have a high demand by design, wide tolerances, or a operational/conditional problem. The HEMI return
system leaves a bit to be desired in stock form, even in some modified forms.

the hemi pans came 1 qt bigger, stock.That wasn't from a HV pump. The pans were too small on all the big blocks. They will retain that much oil just around the crank. A standard volume pump will do the same thing.
still isn't going to pump what the engine needs unless everything is co ordinated to work together/ example, worn out pump on a hi h.p. engine . How did we get on big blocks anyway ? LOLThat would be true if the pump had no relief valve.
