just wondering what your opinions are on if the stock oil pan has enough capacity for a 400 HP 383. Gonna be placing a summit order next week to get the remaining parts we need to complete the build. The engine will have a windage tray and high volume pump. Thanks
 
I would use a Hemi pan, but that's just what I would do, even though the stock type 402 pan would probably be fine.
 
Sort of depends on what you're doing.

Mild street application, occasional 5k blast - yes.
Strip use, 6- 7 qt. Milodon and matching pickup.
I've built plenty of B & RB truck pulling engines that regularly see 6k extended runs. They need a very modified pan to survive.
My personal 383 uses a 7 qt. Milodon, Melling HV pump. I like capacity.:rolleyes:

I have a stock pan. Shift at 6700 rpm
 
High Volume pump = a larger capacity oil pan. Standard pump = standard pan. Hemi pan works well.

I was about a quart or less low on my 440 with HV pump and stock pan driving on the interstate, came up on a deserted stretch and floored it for several seconds. My oil gauge started fluctuating, that tells me that normally at that sustained rpm, there would only be about a quart in the pan.
 
A high volume oil pump pumping at 60 psi and a std volume pump on the same motor pumping at 60 psi are pumping the same amount of oil to the motor.

If a std pump provides adequate pressure, then a high volume is not needed.

Bearing type, internal clearances and valve train oiling method will determine if a standard pump can maintain adequate pressure. These conditions will be the reason a pump cannot maintain pressure, or sucks the pan dry.

You might not need that high volume oil pump as others have mentioned so you don't "run the oil pan dry". I personally have run a high volume pump with a 1/2" pickup tube on a big block BUT I had a Moroso 8 quart oil pan & .003" rod/main bearing clearance. The new motor I'm building will use a stock oil pump & stock 3/8" pickup with a stock Hemi oil pan & a little tighter bearing clearance. I think you should use a stock oil pump too...just my opinion.
 
A larger capacity pan is cheap insurance. You can only run it dry once. I'd at least get the Hemi 6qt pan. Check with Top Street Performance . They list Hemi pans for $49.

I agree with Doug. A couple things I found out about "hemi/six pack" oil pans...
a. They stick down below the standard k-member about 1-1/2". This isn't a big deal unless you have serious potholes OR drive down country roads in your area since the oil pan is no longer protected by the k-member. You "can" add a hemi/six pack skid plate to your existing k-member if this is an issue.
b. I suggest you buy the pan/pickup tube from the same company. I bought a pickup tube that was supposed to be "factory style" & a Milodon "factory style" hemi/six pack oil pan. The pan would not clear the oil pickup tube. I bought a Milodon pickup to go with the Milodon pan & everything fit just fine.
 
What is the 971 pan?

I see there is a MP hemi oil pan that summit offers but says “currently unavailable.”

It’s strange, most of the pans available do not come with the pick up.
