Who has done a 5.7 with a833 4 speed Overdrive ?

Well I got the Milodon and the Holley side by side. Sump area is identical as well as the rest of the geometry appears to e identical. Due to price point and build I'm going with the Holley!

Interesting. The placard I saw in the Milodon booth at SEMA said their pan gave better clearance below the pan.

Something else I noticed is that the Holley pan has "wings" to control oil returning from the top end. Might not be a big deal, but I think the OEM cast aluminum pans have the same setup.

Here is a Challenger oil pan. Similar oil control baffles.

The Holley also has the bolt in baffle, that bolts into the the pan. I assume that the Milodon pan has something similar welded into place. One thing that the Holley pan has, that I didn't know it had until I needed it, is that the windage tray will accept a 4.050 stroker crank without mods. Pretty beefy one at that. Hold your tongue just right to get it to pop into place tho.

I think it comes down to brand loyalty/disloyalty for some people. Outside of that, cost and appeal are the big factors. The cast aluminum had great appeal to me and in the end, it was cheaper. Not everyone but some people have become dissatisfied with the Milodon pan because of drips. Take that with a grain of salt tho. 408 Swinger has had great luck with them and no issues. Both pans have the same disease.. the idler just bumps at full right clock. And even that is with the 73 up centerlink. I don't see either pan working with pre 73 parts.. I could be wrong. I can't remember the user (roadrunner something maybe) but he has the Milodon and actually heated it and gave it a couple of good smacks with his favorite hammer to cure the problem. Nice build but that made me cringe.

Just to follow up on the issues with the Holley pan and the suspension, it appears the Holley motor mounts put the crank centerline about 3/4" higher than stock. This means the suspension really can't touch the pan when using the Holley mounts.

I don't have a trans bolted up in these pictures but the motor should be close to where it will sit in the end. Plenty of room.

Not saying I like that they moved it up, but for now I am ok with the compromises.

Thanks for the reference. I have the same pan with TTi mounts and have accepted the fact that the knuckle may touch at full right turn. Looks like it won't be by much though. I haven't mocked it up yet though.

Yeah, I knew this wasn't really helpful to you since you pivoted to the TTI mounts. But with the discussion and my comment that I would post info after I got my motor setting in the car, I figured I should follow up even though it wouldn't really be applicable to you. But maybe someone will get some useful info out of it.

Great stuff though I was curious as well!
