I'd like to get a windage tray without having to buy some sort of deep sump pan because I don't want to risk having issues with Y-pipe fitment on my TES headers.

So will a Z28 or Moroso windage tray fit in a stock type pan and function??

BTW, yeah, I searched and couldn't find anything. That's where I found out about problems with deep sump pans and Y-pipes though...

ASk the manufacture of the windige tray to know for sure or make your owen.

AFAIK no.

However, the old Z28 pan and a windage tray, will fit fine. That's what I had, along with TES for a while.

Stock L98 pan has a built in windage tray.

I currently have a Summit cheapie pan on it, but it works well. I'm not sure but the only thing this pan has is what I'd call a slosh plate, not a windage tray. It's just a "ledge" above where the oil pickup is.

RB - Thx for the info. A couple of questions on it though if ya don't mind....The pan you listed - it doesn't say whether it holds 5 quarts or what. You happen to know?

Also - The forward (front) part of the pan seem shallower than I one I have on now. Heck, it almost looks like I could fit a tray in the pan I already have easier than the one you posted.....or am I missing something??

Sorry, I just want to do this right....a pan (if needed) that will allow me to use TES headers and Y-pipe and a windage tray. I was considering a crank scraper too, but I've heard that's a bit overboard for the street.

Thanks for the replies, and keep em comin!!

Wow! This certainly died......

I guess it can't really be done with a stock pan, and I would have to buy the studs,locking nuts,washers, tray and pan to make it work.

Turns out - as usual, to be more of an expensive propostion than I realized. I mean - 90 bucks for the pan, 22 bucks for the tray, 7.88 (x5)per stud!! OMG!, 1.15 per locking nut!!

By the time it's said and done it'll cost close to 160 bucks with shipping involved....and I may have to change the oil pump pickup tube too. I didn't even figure that into the equation.....grrrrr....

Would've been cheaper if I planned to have it in the first place - then I would've bought the longer ARP studs, and everything else. Hindsight's 20/20.....

Now i'll have to replace 5 of my new ARP studs, my new oil pan, etc....

The pan holds 5 quarts; plus there's a quart in the filter, for 6 total in the motor.

It uses the same oil pump stuff. The sides of the pan are just straighter up and down, less tapered in, to get the extra capacity.

I ran that setup for over a decade on my 400.

A stock L98 pan doesn't have a "windage tray"; all it has, is the usual baffle that's made onto the pan itself.

You can use regular 3/8"-16 locknuts from the hardare store. No need to pay GM's cover charge. ARP may sell suitable studs too, I'm thinking.

Everything is always more expensive than one realizes.... I did a cam swap into my little brother's L69 MC SS this past week that he just bought, I had given him a ZZ4 cam for Christmas. We used some old used retrofit hyd roller lifters and .080" push rods and some Comp 1416 rockers I had laying around. We did a few other odds & ends, like rebuilt the carb. I gave him some old used but good Taylor plug wires to replace the wasted junk his car had. Still, by the time we put in new springs & retainers (1.25" .... I didn't have any of those on hand ) & keepers & seals, bought the factory's retainer plate, gaskets, hoses and such, plugs, plus the usual little of this and little of that, we were over $300 of misc into it, besides the cam itself. I almost regretted giving him the cam, it cost him so much to put it in!!! And that's not counting any of the value of the $650 worth of push rods & lifters & rockers & plug wires I loaned or gave him.

Thx for replying RB..... I knew you'd fully understand how these little "add-on" projects seem to ballon on you!

But dangit!....ARP will only sell me a "set" of studs to adapt a windage tray, not just the 5 I actually need to do it. - of course. And they made sure the set was even more expensive than paying the ridiculous price for just 5...at 7.88 apiece!!

There's a hardware store a couple blocks away I'll get the locknuts at, and I'll see if they have grade 8 studs I could get too. You just used the teflon insert lock nuts right?

I guess I'll have to do it now since it's pretty much back together and on the stand...I'm thinking of getting personalized plates that say "MNYPIT"! lol

I'll quit whining now...engine is going together like a glove! Hopefully this will be the last time I pull an engine out of this thing for a long while. And it won't smoke (hopefully)....

Depends on how you look at it. Milodon, and Moroso have pans with "built in windage trays" that look almost identical to the L98's tray.

The L98 tray looks pretty much identical to the old "Z28" oil pan, which most performance books quote as having a "windage tray" built in.

The L98 Vette oil pan has a really nice windage tray, and centered oil pickup. But that won't work on the stock k-member.

One of these things is not like the other....

Moroso are welded GM pans btw.

And the trays are pretty much identical, as I previously stated.

Not stock.

"Looks" don't count for much. Reality is more important.

The old Z28 pan DOES NOT have a windage tray "built in". It has absoutely nothing built in, not even the usual horizontal baffle that typical stock type pans like the L98 pan have, only a little flange sort of thing is supposed to sort of "seal" all the way around that the windage tray. It doesn't "support" a windage tray, it REQUIRES one. Would you like to come to my garage and look at one? Then you won't have to worry about quoting "most performance books". A dose of physical reality experienced directly with one's own senses is worth many many "books" (not to degrade the value of reading, only to point out that what people write isn't always accurate).

The stock L98 still pan doesn't come with a windage tray, and doesn't accomodate one very gracefully at all. It has the usual horizontal baffle.

Well, I got all the parts except for the pan, so I decided to see how the tray fits on it. I realized I only needed 4 tray studs instead of five. Unless I'm missing something, four go on the 2 of the main caps and the rear bolts on with the oil pump on top of the rear main cap - is that right?? GMPP site says you need five of the same part number....?? So I bought 5 from them......

Pan is on backorder, it'll be the 30th till I get it. Not sure how this is gonna work though...I didn't have to enlarge any of the bolt slots on the tray in order for it to fit my 400 main caps either, like they state.....

RB83L69

Which tray have you got?

The Moroso one I have, seems like takes 6 main studs, plus the pump bolt.

That's pretty strange about not having to slot the holes out to fit on a 400, considering that the bolts are about ¼" farther apart on a 400 main cap, than on any other SBC block. Oh well...

I bought the Moroso you posted part MOR-23020 from Summit. The 4 small holes it has are already slightly oblong, but it has two larger holes for the main cap in front of the rear one. Doesn't look like it is intended to be bolted to that cap....then would'nt I need 6 studs?? Something's goofy here....I'll post a pic tomorrow.

Looks like some pics were lost, along with a few responses on this thread when the board crashed. Turned out I got an education on what actually fits what.

If you use the studs and pan RB listed above, DONT use the Moroso tray. The Z28 pan didn't even come close to fitting using the Moroso tray with that pan.....Use the GMPP windage tray it calls for instead - Yeah, I know...it's 10 bucks more, but it fits because it has the rounded edges to mate up with the pan. I found all this out when I finally got my BACKORDERED pan from Summit. I'll post a couple pics later.

Here's how the Moroso tray fit.

And the oil pan...

Turned out that even with the recommended parts, I STILL had to dent the pan just behind the dipstick tube because the rear counterweight on the crank was scraping against the inside wall of the pan. Never noticed it till I went to tighten the pan down...

So I took a rachet extension and hammer and "adjusted " the contour of the pan, so it wouldn't scrape against it. Hope I don't have any leaks after this...

what about this? $75 shipped..... has crank scraper and windage tray/gates



i'll see if i can find another one if interested.

The pan I used was MIL-31501, but it won't clear a stock k-member + y-pipe.

I drilled my blower-drain hole last night and used a 3/8 npt stop nut and some loctite. Should work nicer than tapping the pan.
