Update from this weekend's efforts - I dropped the pan again and the plastic tray had several gouges, which is pretty much as I expected. I got a new tray from Jegs to fit for a 4.15" stroker crank. Mocking it up showed that it had plenty of extra clearance so good to go. Firing the motor up afterwards had good results and no more drumming from the bottom end. The rear main seal issue was corrected by removing the billet aftermarket unit and putting the factory style back in...no more leaks! I took some pictures of the rod hardware but I have no idea if the bolts are stock or aftermarket. The motor was built about 33 years ago so not sure what was available back then. I wonder if this might be more of a Hemi issue since never had it on any 440 previously.
68jim The rod bolt with the dimple on the end, it probably has them on both ends, is an aftermarket bolt. The dimple, I believe, is to retain a bolt stretch gauge better .

That's bizarre. By all rights either one should work and the don't.
I wonder how those compare to the production style tray.

In 2004 I bought a stock 426 Hemi crank, rods and windage tray from Ma Mopar. The rods hit the windage tray. Which I thought would be impossible.

On my latest Hemi build I decided to use the new tray and after rotating the engine by hand I noticed it was scraping the crank. I took a cutoff wheel and made slots where the rods were hitting and that cured it.

Are those HEMI rods? The rod nuts look larger than normal or is it just the camera angle Gus Crossbolted maincaps , looks like a hemi.

Hemi rods-bolts ARE bigger than 440 rods. Aren’t deeper trays going against the grain for oil issues (to far from crank)? A hall peen hammer will fix those marks in tray, I’d do that first. The previous owner did just that except with a punch (first picture - you can see the scratch in the punch marks) The whole idea was to get rid of the tray with 2 gasket combo while I had things opened up to fix the leaking rear main seal issue. I did consider cutting notches in the plastic tray and I'm sure it would have worked OK but that also would have been a lot easier with the motor upside down on a stand vice installed in the car. JEGS had the stroker tray on sale and it was a decent deal, so I went that route. Best I could measure with the stroker tray was that I now had about 1/8" to 3/16" clearance. Not sure what the factory intended as far as rod/hardware clearance to the windage tray but think I'm OK with this arrangement. One thing I did notice about the damage on both trays was that it was more pronounced towards the rear of the motor - Evidently the crank centerline is not exactly parallel to the bottom rail?? Or more likely it may have been how the trays were manufactured?? The bigger issue I see is that the new plastic trays do not account for the extra depth you gain with a gasket. The plastic one-piece and the steel factory tray had identical heights when set up side by side. Yes, this is a Hemi and not a 426 Wedge - good eye catching the cross-bolted main... jim
