Best oil pick up for big block with stock pan - 07/03/12 05:24 AM

I'm in the market for a new oil pick up and was wondering if some are better than others.

Melling and Milodon both make ones with a single large radius turn instead of multiple turns like in the stock or Mopar Performance units. I'm assuming that less turns on the inlet side of the pump would equal better pump performance, but wondering whether there are any fit issues with using one of these. I'll be using stock windage tray and stock 402 oil pan on a 383.

The stock MOPAR unit has a "shoe" on the bottom of the pickup which maintains clearance between the bottom of the pan and the screen. Its a good design which is easy to install correctly. Aftermarket units don't have the shoe. Precise installation is required to maintain clearance and if the tube moves around in use you could loose clearance. Even if the pan gets crunched a little the stock unit will still work and maintain oil flow.

I use the stock style replacement.

x3 , get a new replacement for the stock pickup, the pickups for the HP pans are readily available from Mopar Performance.

I like the aftermarket pickup with the "Turbulator" in it!
Otherwise there is NO REASON to go with anything other than a stock pickup.

Actually, both of the pickups in the links below are supposedly designed for use in a stock pan, and both appear to have the "shoe" on the bottom.

The only difference I see is that the tubes have a single bend instead of three. Assuming there are no fit issues, this should be a superior design since the oil would travel a less circuitous route into the pump.

Maybe I'm just overthinking this, just like every other aspect of this build.

The pics on the Summit pages are probably generic, the number of bends in the stock tube differ with the installation and so will the replacements.

For a stock pickup, just set it on the bottom of the pan? I am changing the pan/pickup in the Dart.

When installing the pickup, anything on the threads or just snug it tight?

Do you know the Mopar Performance part number?

Looks like Mancini and Summit offer two choices by Mopar Performance, # 4529564 or # 5007848.

I like replacing the 402 pan with the 1970/71 Street Hemi 440 6 pak 6 quart oil pan and pick up. I use the stock 3/8 pick up on my 518 C.I. pump gas stroker in my Duster, I shift it at 7000 + RPM on every run, car runs low tens at 132+ MPH, no oiling problems so far, going on five years with that set up on several other motors also

What I use also. Mancini sells the kit with stock style pickup for reasonable cost. Bullet proof to 6500 RPM, with care good to 7000+ RPM.

I got the truck (rear sump) pan kit just today. It is replacing the 402 that is on the motor. Hemi pan does not clear the rack on alterktion. Found some other posts searching and saw that recommendation is zero to 1/8" clearance for the pickup to pan. Also got a windage tray since it was just a little more than getting the gasket separately.

OP I didn't mean to ask/high-jack earlier.

No worries. Same subject matter so better to cover it under one thread instead of starting another IMO.

Hemi pan sounds like a nice upgrade, but I'll be using my 402 pan for now.

The 1970-71 Hemi 440 6 pak pan fits all the B body from 1966 up to 1971 , maybe even later It is longer in the sump and does not hang down like the 1966 to 1969 Street Hemi pans do so no mods to the K frame needed to protect the oil pan The 440 6 pak pick up is straight also, not with multiple bends in it like the 402 pick up has

What oil pump are you using? How is the fit, ground clearance, and turning on the A-Body Duster?

The idler arm does hit the oil pan when making hard right hand turns but not enough to bother me It does have hedman fender well headers also so that may have something to do with the turning radius also I use a either a Mellings or Speed Pro high volume oil pump, which ever one is cheaper at the time I'm building the motors I build I do cut the bypass spring down to lower the oil pressure to get 10 lbs. per 1000 RPM, stock they make 80 lbs idling when cold That is the bypass pressure usually so I let it warm up to get the oil hot and then whatch the oil pressure readings on the dyno test and cut one coil off at a time and then make another pull to get the pressure I want One complete coil is usually enough to get 70 lbs at 7000 RPM I cut one half off to much on my 518, it ended up having 65 lbs at 6500 RPM and the same at above 6500 RPM, that is with 5Wx20WT oil hot

Thanks for the tips... I always thought a 6qt pan would run dry above 6200rpms with a high volume pump.

I guess I dont need a 1/2 tube either then since your running 3/8.

What is your normal oil idle presure (if you have 10lbs per 100rpm, 900idle you have 9psi)?
Is this safe for a street car?

The oil pressure varys with oil temps, I use Valvoline 5W20WT non synthetic oil, it will drop down to 18 lbs at 800 RPM with the oil temps above 185 F It has 30 lbs at 1000 RPM and 40 lbs at 1500 RPM, 65 lbs at 7300 RPM in high gear Its all good I do have to keep the oil pan at or above 1/2 quart below the full line, if I don't the oil pressure will drop off some after letting off on one of the 130 MPH+ 1/4 mile runs it makes I use the Federal Mogul narrow full groove truck bearings also I do use the stock 1970/71 440 six pak Mopar 3/8 pickup, I make sure it is no higher than 1/8 off the bottom of the oil pan It doesn't hurt to have it touch either as long as it doesn't hold the oil pan off of the block before tightening I also use a crankshaft scraper (I make my own, you can to ) also to help free up some power and keep the oil in the pan

Are you running 1/2 above or below the full line? This statement confused me.

How do you make a crank scraper?

How many RPM can you go with the an unmodified HV pump, 3/8 P/u and no mods in the 6qt hemi pan?

I was trying to get into this thread. Looks like its a little old now. Hope I can get some valuable help here. Putting together a 440 for a project and was concerned about the oil pan pickup clearances. I have a Hemi oil pan P/N P4529884 and Mopar windage tray and 3/8" pickup P/N 2899808. When I dry fit it, it seems like the pickup was too long. I adjusted for gasket and windage tray thickness and added approx .200" extra clearance. It seems like it will fit however the pickup is right there on the bottom of the pan. I'm sure they're touching. Is this normal or should I get another pick up? Also there is no way X 10000 I could torque these to 200 inch pounds without all the gaskets cracking and smooshing out. When the time comes I was thinking I should tighten until the RTV pooks out and then stop and let it cure, check later etc. The original torque specs were assuming that the pan would be right on the block, right? thanks in advance. ......

The stock pickup is designed to have the shield on the bottom touching the stock pan. If you need .200 gap at the pan to block mating surface something is wrong. The pickup part number you list shows for C body applications, which may or may not be the issue, I do not know what the differences are but I do know that the C body used a different pan as well.

Re: Best oil pick up for big block with stock pan - 12/28/15 03:52 AM

The gap was the combined gasket and windage tray thickness. If it wasnt for that then it probably would not fit at all.

For a B-body (charger) what would be the correct oil pick up then if using a hemi oil pan. Anybody know? I've researched until I'm blue in the face and there seems to be a bazillion combinations.

Re: Best oil pick up for big block with stock pan - 12/28/15 04:25 AM

There were at least a couple of different versions of the hemi pan. I run the re-pop that Mancini sells with their stock style pickup. They also sell pickups.

As mentioned, the stock style pickup has a "shoe" that rides on the bottom of the pan to maintain clearance for oil flow. It should be touching the bottom of the pan. This also reduces vibration and stress on the pickup. Sounds like the one you have may be OK.

Some aftermarket pickups have the shoe, some do not.

if a shoe were needed to be added to a pickup to maintain support, what kind of clearance would be generally accepted ? 1/8"? 3/16"? 1/4"? i'm thinking you could make a shoe from 1x1/8" angle shaped to fit your application/pan , then tacked to your pickup. thoughts on this ?

No shoe support needed for support on any of the Mopar stock oil pickups, as far as clearance from the bottom of the pickups to the oil pan I use the oil dipstick to measure through the oil pan drain plug thumbsIf it will slide under the pickup on the flat side and not slide through turned sideways I use it, if it won't slide through all the way on the flat side I'll use that also thumbs If it is more than the width of the dipstick off the bottom I correct it by pushing(bending the tube) the pickup forward towards the timing cover a little at a time with my hands scope thumbs

Problem solved. With a straight edge and a tape measure. After some measurements forward and back left and right up down etc. I could see the the pickup puck/shoe was leaning up at an angel just enough to lift the front of the pan. With a BFW I gently tweaked it back and voila the pan laid flat with approx 1/16" between it and the pickup. Two pan gaskets were sacrificed but oh well, better on the stand then in the car. Thanks all for your input and advice.

There is only one pickup for that pan in a big block so it is the one that mopar lists. It may require some tweeking to sit properly but it should pretty much be touching the bottom of the pan.
