From the 70 service manual:

426 Hemi, 440 6 Pack and 440HP engines only- 6 qts
Add 1 additional qt if filter gets replaced.

Thanks,
i just purchased the car and the dip stick reads high with 6 qts. my buddy's 70 rt charger 440 holds 7qts with filter change plus the chargers dip stick is shorter. guess i have the wrong dip stick?

Look at your oil pan, see if it has a number stamped onto the rear part, if so post that number

If not try and post a picture of the sump, there are around 7 to 8 different stock Mopar made oil pans that will fit on your motor in your car

I've never heard that the 440 HP single four barrel motors came with the 6 quart street hemi/440 6 pak oil pan

70 440 4 barrel had the same pan as 440-6 pack and 426 hemi. It is often referred to as a 6 quart pan.

70' 440 MAGNUM's (HP blocks) or police option motors
did have the 6 quart pan, along with the above mentioned motors. Standard luxury car (C-bodies) or lo-po 440's had the 5 quart pans. 1970 Challenger R/T - 440 Magnum (4 barrel, HP Block) has a 6 Quart pan.

Thanks for the info guys.. Now i need to know the length of the dip stick. I guess i have the wrong one. If this is the case the previous owner
was running this car 2 quarts low...great.

Let me bet that the new one is a chrome Mopar replacement, yes? If so they need to be calibrated

I cut my tube down with a tubing cutter to get the stick to read correctly after filling the pan up and PRIMING the motor

I have a motor on the stand right now that has a aftermarket replacement 1970-71 6 quart Mopar oil pan on it, the sump is five inches deep and ten inches long

The correct pan is the 6qrt-same as the Hemi and the Six Pack. The correct length end to end is 25" on the nose for the dip stick. The length of the "stick" portion only without any of the handle figured in is 21-5/16".

Cab, I was kinda foggy about those HP 440's (particularly the early 67 to 68') having
the 6 quart Street Hemi pan, too (awhile back). Didn't Direct Connection offer it as an (over-the-counter) upgrade package for the 383/440 oiling system for drag racing as part of their "shared" speed secrets program back then? It's possible that the later HP's (69'-71'), were already fitted with the pans on the line by late 68'.

Not that I have heard of, the 1966 to 1969 Street Hemoi pans held either 5 quarts or 6 quarts depending the FSM you had

As far as I know the 402 pan was ths standard 383-440 magnum Hi Po pan for those cars, especailly 1968 to 1970

I had a original 1970 Baracuda 383 4 speed car and I help some people that had a original 1969 440 GTX, they both had 402 pans on them. I bought a 1970 V code R/T Charger 4 speed car in 1989 to restore, it had the 6 quart Hemi -6 pak pan on it, that was the first one I had seen

I was told by several factory backed Mopar racers, Dick and Mike Landy,Bob Lambeck and Joe Alread to run 5 quarts in all the stock pre 1970 oil pans that we ran(drag raced) with windage trays

You'd think that MP chrome "replacement" stick would have a small note about the fact it won't read the correct level using the 6 QT pan to give someone the heads up on that situation...What is that stick indexed for ??? Anyhow....Install the 6 qt pan with that chrome stick and even 5 qts reads "about 1/2 a quart over"according to what's marked as full on that stick...Figure out what the filter you run holds then add the correct amount of oil and remark the stick..

Do you know the corrrect length of the dipstick tube from the block ferrel(SP?) to the tip of the tube? I am putting the Mopar after market Chrome dipstick tube and dipstick package in the motor that the oil pan I posted the picture on?That would give me a place to start instead of cutting a inch at a time off of it until I get it close

I have, in the past, put 6 quarts in the pan with the engine on a engine stand and then level it front to rear and side to side and started cutting the dipstick tube until I got it where I thought it measured correctly full

I have done it also by putting in five quarts in the pan and then cut the tube until the dipstick read at the add mark, added the extra quart and it read full

That told me the chrome dipstick is accurate, getting the tube lenght was critical
