'70 440+6 Roadrunner Oil Dipstick

I've decided to get a new oil dipstick and actually use the motor mount bolt "loop" so I don't pull it out of the block. I've added Hedman 1-5/8" headers & I have the #1 cylinder's primary pipe going right over the top of the #3 cylinder's spark plug before turning down after exhaust port #5 (runs left-right, sorry no picture). I've been using a slightly modified "el cheapo" chrome dipstick & I think I bent it to clear Hooker headers I had on there before, if that matters.

I've got an aftermarket oil pan on the car (Milodon "six pack" style). Even though I marked the dipstick after I put in fresh oil (7 qts. with filter), I'm still not 100% sure my oil level is correct. My thinking is that "whatever" pan you put on a 440, the oil level distance below the block's oil pan rail should be the same.... deeper pan = more oil, but the "full mark" should still be correct regardless of the pan you're using. Does that sound right?

Here're my other questions:

1. Would another "el cheapo" dipstick like shown above read my oil level correctly? OR, will I have to calibrate it myself when I do an oil change?

2. Would the factory OEM dipstick clear my headers?

3. If I had to bend a factory OEM dipstick to clear my headers, would that affect the "full" mark?

4. What is the correct Chrysler part number for a '70 440+6 Roadrunner? 3698500?

I'm sorry this is sort of rambling. I'm wondering if I'm worried over nothing and/or over-thinking this situation. I just want to be sure my oil level is at the correct height. I have an oil leak and I'm wondering if I'm over-filling the engine. THANKS!

on my 440 with those headers i placed the dipstick (looks like the one you showed) between the the header pipe and the block. fits real nice. as far as the pan depth, the stick isn't necessarily reading how much is actually in it but rather how full it is.

(yes, you're over-stressing it)

I put the reproduction tube in with an NOS dip stick between the TTI tube and valve cover with no problems. Have to do it when the header is loose.

That's sort of what I'm thinking.... how full (how close to bottom of block's pan rail) the pan is. That means that if you had a factory OEM dipstick & tube and you put a Moroso 9qt. deep sump pan on the motor, the dipstick would still read correct (just the pan holds more oil).

Can anyone else confirm this?

The problem that worries me is that the factory OEM dipstick is long gone....not sure I ever had it. All I have is this bent up aftermarket chrome tube & stick calibrated to who knows what. PLUS, I'm not 100% sure what the volume of my Milodon oil pan is.... supposed to be a "six pack" pan.

Any other comments/tips are appreciated. Anyone know the factory part numbers?

Purple beeper you are correct. Pan depth does not matter, just holds more oil. It is the oil level below the pan rail. I would find a tube that fits and dipstick. Fill engine with oil, depending on pan size. Then mark dipstick. That is how I did my 440 truck with an 8 quart pan. My dipstick mounts into pan.

On a problem child what I do is fill the pan with the # of qts it holds, (4 for instance) on a level surface & remark the stick at that point OR if using a longer OE or aftermarket stick, shorten the dipstick tube till the oil level is right at the OE Full mark on the stick. So that with the filter filled and the oil passages primed, there is exactly 4 qts in the sump when you check it in the morning before starting the engine.

3462415 is the tube part number and I think you can still buy it

Thanks Morty.... do you know the number for the dipstick too and/or the tube + stick?

I don't think it depends on the level below the block rail but rather the level in the aftermarket pan with correct pick up,if advertised @ 7qt then that's the level in the pan as designed,you need to note the level on the dip stick and adjust as/if needed,the full level is the level mark the stick & don't let it get low.

Yes the dipstick is 3512078 but I have not confirmed how correct that part is. The tube I know is correct.

I found this over at Roseville's website. I'm not concerned about "correct". I'm making an ASSUMPTION here that the #2078 (70-71 B/E body big block) is bent differently than the #9246 (66-69) or #2840 (64-65 B-body or 65-68 C-body) due to differences in their exhaust manifold shapes or something like that. Is that right?

They all bolt to a motor mount bolt, right?

I'm sure I'm over thinking this, but could I use ANY of these? I've got a '73 block in a '70 car with headers. Will they all be accurate? Will one clear headers better than the others?

Any ideas/tips are appreciated.

The 67-69 and the 70-71 Manifold shape is the same. I think the difference was if the tube came up between the manifold and valve cover OR on the outside of the manifold.
