Moroso vs Milodon 7 Quart Oil Pan

Wondering if any of you have an opinion of which oil pan is a better fit and quality. My car is a 64 Cutlass and I was leaning more toward a Milodon for my 455 but I have the opportunity to get a good deal on a Moroso. I'm in the market for a 7 quart capacity. Thanks

Get a Rocket Racing pan, pickup and gasket. Best quality IMO.

I've had issues with Milodon and I know guys had problems with Moroso too.

Milodon pans are thin, with mediocre welds.

I had one of their pick up tubes fail (poor weld) that cost me an engine rebuild.

Caveat Emptor.

I wanted to put a Moroso pan on my 455 and put one on it when the engine was on the stand. It leaked. I contacted Summit and they let me swap for another one. It leaked on the stand too. So, I sent the 2nd one back and got credit towards a Milodon pan. It didn't leak!

I ran an OPP 7qt pan. The rails were warped like most modified pans, although Andy swears up and down that his are the only ones that get built perfectly. It bolted up and sealed find though.

The welds were quite strong! I eventually broke the back weld after landing on the oil pan for the 10th time or so. Turns out a deep pan + >3" lowered front + medium-soft shocks = broke pan. Who knew?

Still building engine. But looked down at the pan around rear part of crank. Gasket is wet and had some fresh oil to be there. Looks like the seal absorbed it. Hopefully this won't be an issue when I run it:/

I'm thinking of dumping my milodon pan and pickup before I run into any issues. It's just money

If it's leaking now dump it. Imagine when the oil gets hot.

You might be able to get a refund.

The Felpro kit for the diesel - OS30471C - is a steel core with cork for the rails. Very good set. I still use a spray gasket maker on both sides of the rail gaskets, dabs of silicone on the ends of the rubber seals and where the rubber meets the rails, that's it.
Moroso also makes a nice kit, but don't believe it when they say it's "tear proof". It'll tear if you just yank it our of the packaging.

Just got rocket racing pan. It appears to be built a lot better than the milodon. Looks like a winner!!

No luck on second attempt with rocket racing pan and there seals. Put Rtv in the four corners where the gasket overlaps the rubber seal. It's leaking from the right rear bolt see pic

This is the same thing that happened to milodon. Maybe RR is made by Milodon. Gunna call and check tomorrow with rocket racing on Return. On to Canton once I hopefully get this returned.

Looks like the gasket was installed incorrectly. There must be a blob of RTV between the rubber seal and the block where the cap meets the block. The rubber seal has some indentations on the underside to hold RTV. I put a pea sized dollop in the cavity between the cap and the block where the seal slips in, plus a very small layer on the step on the block where the flap of the seal lands. Then another small bit where the side gasket lays on top of the rubber seal. Same on both sides on the rear.
Similar with the front - RTV provides the seal between the side gasket, rubber gasket, block and timing cover.
