have a 67 coronet that I am swapping a 77 440 into. Was told it was out of a power wagon. Oil pan has huge dent in it and is a rear sump. Do center sump pans work in the b bodies? And are windage trays necessary?
 
Everything you always wanted to know about 440 oil pans:
http://store.440source.com/Oil-Pans/products/54/
Unless you're looking for HUGE capacity or some such, I recommend the top one on
that page - it's the "hemi" and 6-pak pan, a bargain for the price.
Gives you the more capacity as a stock RB pan does, yet does not hang any lower
and uses the stock pickup.
For all b-bodies '66-'72. Fits great.

As far as windage trays go, some who know more than me will tell you they
are unnecessary on a street 440. I figure what the heck, why not anyways?
Does no harm to be in there either way.
 
Years ago Mopar Muscle did a dyno article running a windage tray on a 440.They concluded that the tray was effective with RPM's at or above 6,000.

Thats a good bit of info. I am not going to really be touching that range with mine. I was going to be replacing the pan anyway and and thought maybe I would add one but sounds like it’s not worth the money for my application. Thanks for the info.
 
I pulled a 440 from a motorhome and IT had a windage tray in it. You think those engines were spun to 6000 rpms?

I disagree. A windage tray is actually capable of increasing the output of the engine by an amazing amount given its cost and function, and it helps keep the oil where it belongs, doing its job, and not getting whipped up too.
The factory would not have included them if they didn't provide significant cost/benefits.
I have one in my 440+6bbl, and I had one on my 71 R/T Charger, because Ma MOPAR thought it should be that way.
If you change the oil pan, there are different windage tray solutions.

Save yourself the aggravation of 2 gaskets and a windage tray. Get them in one piece...

Seems like a good idea, but what happens if there is a problem with the gasket seal at some point?

I found out that my oil pan leaks came from the oil pan not being perfect. Saying that, I have that 2 in 1 gasket/tray combo in both my 440's for years and no issues so far (after installing new pans). After reading the reviews I don't see anyone saying they ended up leaking and all praised the product.

Sounds great, and just the thing if the OP has a pan/oil pickup that it works with.
Thanks.
 
In my humble opinion , the shallower/ lower capacity pan that you have, the more you need a windage tray. It's job is to keep oil from "roping " (wrapping around) the crank. The idea of a deep pan is to get the oil farther away, the idea of a larger capacity pan is to have more available to the pickup.
Let's say that you have a shallow, four quart pan. It's possible to get a couple quarts wrapped around the crank, and another lubricating the top end. That leaves one quart in the pan. Anything you can do to keep oil off the crank , a windage tray, will help.

AndyF also said in his Big Block Mopar performance book that while some high capacity oil pans have been used with less than capacity oil in them, to keep the oil level from being close to the crank, he had some burned bearings as a result of problems with that scenario.
I'm looking at the Milodon road race pan for the combination of more capacity but great ground clearance.
I am far from having made a decision, and I will consult with the builder as that develops.

Motor trend engine masters did a segment on running a deep pan with less oil, but I think from a horsepower viewpoint , ignoring durability I think. I'm not a subscriber (yet. There's a special on, $1 a month instead of $5) so I haven't seen the results. Sure would like to though .
I think milodon makes a road race pan too. I'd like to know which fits better. I'm betting neither will fit my 62.
