So I'm looking at a moroso 10 qt pan for my olds. I have a stock volume oilpump w press in pick up. Summit says it's 7 1/4 deep at the sump my original auto pan is 7 inches. I can use my stock setup right? All that fancy bolt on pickup stuff I can only find hv pumps I'm not down w an hv pump because I don't wanna push all my oil upstairs comments?

Me and most guys on here with olds all run a hv pump. I've got a 12qrt pan right now and I just did return lines from the heads to pan and it was the best thing i ever did. I don't have any restrictors or any of that bs. Iff your motors pulled Id recommend doing this. I can run 5k rpms all day long without pumping my valve covers full of oil

it's out bro heads are in the machine shop it's now a short block I did put oil restrictors in number 2 3 and 4 already. U think an hv pump l be ok? I may look into doing what you did pretty sweet drains I'm planning on aluminum heads next season what did u do just tap the pan and go right through the raised side of the head?

I'm not gonna turn over 4500 rpm w the way my pumps set up I'd be surprised to see 5k I kept it in the low end of the spectrum for longevity s sake anyhow. Maybe a change in impeller s will prompt some other changes but that's not gunna be a while.

Yup drill and tapped a 3/8 npt hole. There's a old hot boat article and it has the exact measurements on where to do it I have it saved on my iPad if u need it u can probably Google it tho

I really just want yo kno whether a stock pick up will fit in the pan or naw

It'll fit but probably won't be in the bottom of the pan where you want it

HV oil pumps put a huge load on the distributor gear if you don't have the bearing clearances to bleed off the extra flow.

I run an olds 455 I have had mine to 4500 maybe a little higher but not much. And I try not to keep it there longer than a min or so. Now I have a 10 qt. pan with the right pickup . Stock oil pump and I maintain 40 psi off idle . About 20 idling warm . No oil restrictions just opened up the oil returns in the heads.

I have a sbc in the fishin boat, and can keep 45-4600 rpm for eight, yes, 8 miles, the oil pressure was at 25 lbs at idle after that run.
At speed it was 50-55 lbs
dominator pump with an 'A' impeller... gps'd at 55-56 mph.

Oh, Stock L-31 pan...5.5 qts

Yah but that is a sbc ! The oil system is bullet proof!!! Hell the whole motor is. Now a olds has its issues . I really like it but I do have to watch what I do to it.
