I was wondering if anyone has had a chance to use the new pan that Kevko came out with? Comes with a built in crank scraper. My 414 build is coming together and we've already decided to use Kevko again. I'm just wondering if there is anything to gain?

Hey Brian, I bought one after reading about the issues with the Milodon pans in the last few years.

I had it shipped to my builder, he thought it was a great quality product.
Only dyno time so far and no issues.

I had my engine guy( on his suggestion) fab a scraper for use with my Kevco pan.
He told me it’s probably worth 3-5 horsepower. Charged me a little over a hundred bucks to make it. Thought it was a good investment.
 
yeah, my bad. It is a windage tray.

I reached out to Kevko to see if it will work with a 4" crank. I probably won't hear back for a few days. Merry Christmas everyone!
 
Their description from their website,


Description: Our 273, 318, 340 Chrysler Stock Location Oil Pan is fully equipped with a gate assembly with 2 trap doors, crank scrapers and front and rear oil baffle, and now with a full length internal windage tray. The new windage tray will eliminate the need for any stud mounted windage tray, and still perfectly fits the Kevko M301-1 Pickup Tube and your stock dipstick!This fits all standard Mopar K frames and uses the Factory Dipstick. This pan also has an oil level fitting on the side for initially setting your dipstick, or drag applications not using a dipstick.
 
A legit crank scraper will be totally dependent on your rotating assembly- crank stroke and counterweights, rods used, etc.; and they don't specify any particulars.
That's just a windage tray, unless they include a separate "file to fit" scraper that's not pictured...
Looks like an awesome pan, though.
 
i have installed a chev small block scrapper in my 273/340, engines. have to trim it some around crank, and drill bolt holes to fit mopar block. also cut pan gasket to butt against scrapper at both ends, then spread a silicone bead full length of block to seal it it. just food for thought
 
I received an email back at four o'clock on Christmas Eve from Josh in their tech department. That's pretty good customer service. He confirmed that yes, the pan works great with stroker cranks.

Their "scraper" is the narrow piece welded to the side of the pan. The larger piece with louvers is the windage tray.

The narrow piece looks like it could be a pretty good place to mount a proper scraper that is fit to the rotating assembly. I wouldn't expect a mass produced pan like this to have a proper fit on the scraper, especially with the tolerances a sheet metal shop is working to. If I recall correctly, you want the scraper to be as close as .040" or so to the rotating parts? Probably better than not having anything but I think I would go through the effort of making something to fit.

I'm not sure why the drain scallop features on the windage tray are punched towards the crank. I would have thought you'd want them to go the other way to help the oil get back into the pan.
 
The only issue I had was the drain is outside the gated sump area. So with the one way gates, it took FOREVER to change the oil and you might leave a quart of old oil in the sump. I welded in another plug in the sump area.

Is that pan aluminum or steel? Didn't see it in the description.

Seems they would scrape windage from the rotating assembly and push it down to the sump?

This^^^. What they call a scraper isn’t really doing much if anything.

The windage tray does more than one thing.

It breaks up the oil being slung from the crank.

It reduces the entrained air in the oil.

And it keeps the oil in the pan from getting bounced up back into the rotating assembly.

There is never a reason to not run a windage tray unless you have a dry sump.

Even then they help.
