On my 455 build for my 64 Cutlass I have the options of a dinged stock pan which I could straighten and a Toronado pan which may need a different oil pump and definitely need a different pickup. Which one should I use or should I just bite the bullet and get an aftermarket higher capacity oil pan? It is a fresh rebuild with aluminum heads and intake, aluminum roller rockers, a hot cam, and 870 Holley. It will be a driver, no racing (except for the occasional street light challenge.)

You have a wide variety of choices. The Toro pan will require a new pickup, but the oil pump is the same. While the Toro pan does hold a little extra oil, the design of the pan with a cross-wise ridge to clear the RH axle shaft pretty much negates any advantage due to it blocking oil drainback into the sump. There are many repro stock pans available as well. Most higher capacity aftermarket pans will either compromise ground clearance or starter access. You likely don't need that hassle for a street-driven car.

I would go for a higher capacity since your engine far from stock.

There are only a few reasons to run a higher capacity pan. First is to prevent sucking air during high-g maneuvers (cornering or heavy acceleration or braking). This is unlikely to occur on the street. Second is that the larger oil volume will delay oil heating, which is useful on a drag car that only runs hard for a few seconds. Once the larger volume of oil gets hot, it will also take longer to cool down, so again it isn't clear that this is a benefit on the street. Finally, running a larger pan could allow you to lower the oil level while maintaining five quarts or so. This will reduce windage losses, again, primarily a benefit for drag racing.

I would find a BBO oil pan. I'm not sure if a SBO pan will clear the crank and it does not have the baffle in it.

It would be best to find a pan with baffles in the front and rear of the sump, or add them. Toro pan is good if you heat and flatten the hump referenced above (don't use more heat than needed or you will warp the pan). The Toro is flush with the bottom of the crossmember, as is a 7 qt. aftermarket pan so both can use that pickup for the Melling pump; you might have to massage the Toro sump a bit as it has a small step in the bottom--I am not sure where the pickup will be. Last, the 8 qt. aftermarket pans come an inch below the crossmember and the big box won't clear the crossmember if you are installing the engine with transmission on it-you will end up with the assembly at about 45 degrees, front corners of the pan on the crossmember and bellhousing area of the transmission against the firewall hump.

The small block oil pan is the same but does not have the baffles.

I bought what they called a 5 qt. pan from either Jegs or Summit, cant remember now which one. Looks just like the stock 4 qt. pan. So 6 qts. with the filter. It was very cheap, much less than the 7 qt. pan.

I think all pans are advertised by capaicity with filter. If they called it a 5 qt I believe it is 4 qt + 1 qt for filter. Stock is 4 + 1, Toro is 5 + 1.

If you want to spend the money, I would get the Canton Racing oil pan with the trap door baffles.

While looking for oil pans I found this 7 qt from Speedmaster:

Never heard of them and was wondering if anyone had used one. It is half the price of a Milodon or Moroso.

Some of the Speedmaster / ProComp stuff is excellent. Some of it is total junk. So make sure they have a simple return policy. Also be careful of hidden fees, especially if paying with CC and be sure of the shipping arrangement and costs.

As far as pan volume, more is always better. Large sump means more surface area to transfer heat out. More oil means it is in the sump longer and cools more. More oil also means it goes through the engine less often in the same amount if time.

The Milodin 30305 is the best fitting aftermarket 7qt. pan in a 64-67 frame.

The pan i bought from Jegs is a 50280 it states 5 qts plus filter, they also have one next to it states 4 qts plus filter. I just hope i didnt buy what i already had! They make it sound like it will be a total of 6 qts. Ill have to call them.

Smitty275

I'll bet 100/1 that it's 4+filter.

rpinnt

Wondering what you found out. From the Jegs site on the 50280 pan: "Stock depth, stock capacity and stock baffle design re-uses your stock oil pump pickup..." If I had to guess I think you got a newer (shinier?) version of what you already had.

I used a 7 qt pan and as mentioned above with an 8 qt pan I could not install the engine and transmission together.

How hard was it with a 7qt pan?? Will it go in with the tranny??

I'm getting ready to drop my 455 in, it has a Milodon 30305 7qt pan.

Stevec

70cutty that's the pan I used and the engine and transmission had to go in separately. Me and Steve Minori fought that **** for hours and it wouldnt clear the crossmember.

Separated the the engine/transmission and the engine dropped right in.

It was going into my 68.
