I saw a video of an Aussie windage tray for one of the six cylinder hemi engines. What was unusual was how the windage tray was mounted. They used metal tabs under the main cap bolts in three spots. Then the tray itself was bolted to the tabs. Has anyone ever seen this sort of mount? Does it seem like something viable?

Interesting, yes eliminates the issue with coming up with special main bolts, good idea.

Looks doable and applicable to our slants. Thanks for sharing.

Not trying to be negative....but whatever those brackets are made of....it better be good steel. If we buy expensive ARP chrome moly hardened washers because of their properties, the same can be said of those brackets as they essentially a washer as far as the bolt is concerned.

If it were me, I'd look into a way to drill and tap the head of each main cap bolt, ala 340 Chrysler.

But the brackets would work, too!

I am wondering if 1/8" mild steel would work. Possibly something thicker?

That is what has been done in the past. All the Jeffrey trays used Grade 8 bolts that were drilled and tapped by hand. It is pretty tedious process to do by hand and is the main reason I have not done a run of the trays. The 340 bolts are way to expensive for my tastes. Yeah I'm a tight wad!

I am not trying to be negative or argumentative but, do we really need ARP washers for these engines? I wonder how many specialty fasteners were used in the Hyperpack 170s that ran at Daytona? Just thinkin'. Comments welcome.

No...but they're cheap insurance!

On my Slant 6 I used ARP's on my con rods but the mains and head bolts are stock.

Either way, the reason they use hardened washers is a 'soft' steel will have the tendency to squish/walk out which won't help matters.

I get it. Perhaps they are using hardened brackets. IDK.

GergCon raises a valid point, so yes a bracket with the hardness of a grade 8 washer would be appropriate.

I would think a bracket that hard would vibrate, fatigue and then crack

To vibrate the bracket would need freedom to move.
Those windage tray brackets are very short in length and restrained at both ends.

Has anyone tried something like this?

Or........you can just throw the windage tray in the garbage and use a scraper.

lol. I gotta admit, windage trays are pretty dated. I've used scrapers and the Teflon coated, diamond-mesh, uni-directional screens for some time now. Of course, I have no actual data to back that up...it just seems better!

You've made me curious...I've toyed with the idea of a dry sump...has anyone done that before on a Slant?
