I am in the process of buying a new oil pan for my LT1 and figured that I'd just compile all of the information here for future searches people may do.

I have a 3.875 stroke in my engine, so I'll need a pan that will clear that and have good windage. Here is what I have come across after searching the forums.

Stock Oil Pan
Stock Oil Pump
Stock Pickup

Modifications Needed: Clearancing the pan for the stroke with a ball-peen or rubber mallet and doing some slight modifications on the stock windage tray.

- A good amount of big power guys have used this setup and had zero issues but if your not confident in clearancing something like this and making sure your rotating assembly doesn't have any interference then you might want to consider the aftermarket.



Canton 15-242T
Canton Pickup
Standard or HV Pump (Most Manufactures)

Modifications Needed: Nothing serious.

-This is the pan most LT1 users choose, It is a nice piece but has been prone to leaking because of faulty welds or warped steel. It has a low oil provision and a great windage built-in too. This pan holds 5qts.



Milodon 30909
Milodon Pickup
Standard or HV Pump

Modifications Needed: Nothing serious.

-This seems to be the "sleeper" LT1 pan. It has some reputation for hitting the steering rack once installed but some users have just put spacers between the motor mounts to alleviate the problem. A great piece, no bad rep for leaking and good capacity/clearance. This pan holds 6qts of oil.



Moroso 20185
Moroso Pickup
Standard or HV Pump

Modifications Needed: Nothing serious.

-This is considered to be the copycat Canton Pan from Moroso. It's a 5.5qt pan with a 4.125 stroke clearance, built-in windage tray and oil level sensor provision. This pan holds 6qts of oil.



Stef's Aluminum Pan 1030D
Stef's Pickup
Stef's Standard Volume Pump

Modifications Needed: Unsure. It includes a windage tray but I have seen a couple people use the stock windage tray on the main studs too.

-A pretty good option and package that Stef's offers, it is already clearanced up to a 3.875 stroke and the pump/pickup is designed for the pan. This pan holds 7qts and is the most expensive mainstream option, costing about $430 for the kit.

Other Options:

Some people have used 1-Peice Rear Main Seal SBC oil pans with the LT1, however I do not have any p/n's. If you know of any, please let me know.

Pickup & Pump Selection:
-When getting a pickup/pump make sure the diameter meeting both is the same, for example: a 3/4 Pickup to a 3/4 Pump and so forth.

-Oil pumps are not all equal, the information out there on HV pumps is mixed and sometimes misleading. If you are building an engine, see what your engine tolerances are set too. That is the most determining factor in Standard or HV pump selection. Most people think an HV pump nets more power and oil distribution but in reality on most cases it robs power and heats oil up a lot faster then a standard pump as well as the potential to lose pressure in higher RPM.

the canton 242t requires the slight modification speed density referred to earlier as well as some clearancing to their "crank scraper" for the dipstick to clear if you have 4 bolt mains 2 bolt blocks would not have the same issue. I put crank scraper in parenthesis because I feel that it leaves much to be desired as far as crank scrapers are concerned but hey, its the thought that counts. As far as the sealing goes I will come the the defense of canton and their quality control, my oil pan was absolutley gorgeous out of the box, welds were perfect, pan rails were flat, and if you know how to make ANY oil pan seal than you can also get this one to seal. Mine went on flawlessly and is sealed up tight as a drum. No loss of ground clearance and it easily clears stock k member providing you have good motor mounts. This pan is a little on the pricey side but after recieving the pan and looking closely at the craftsmanship I feel it is worth the money.

I'm using a Jeff johnson Billet pan with a Titan gerotor oil pump for my 8k rpm LT4 buildup.

I used a Canton pan before and the rails should always be checked for flatness too. Some weight on the pan is required to keep the pan from deflecting when flattening one side it's pretty flimsy. And check for leaks before you install it. I had to have a few corners and seams welded again because they leaked like crazy.

At what point should you be replacing the stock oil pan?

I have a sbc moroso 7qt oil pan on mine. Dont have any part numbers but it has the dipstick on passenger side. I have a tubular kmember so it fits great and does a way with the leak prone oil level sensor.

I thought the Canton was a 6 quart pan.

It's likely what I will be using in my build.

be careful when using the milodon 30909 and what oil pump you choose. They do have a pickup if you use the m55hv high volume pump, but if you want the standard volume melling 10554 they do not make a pickup for that pump.

I had to buy a milodon oil pump and use their pickup which was made for that pump and pan, i figured this out the hard way when the pickup they originally sent me wouldn't match up with the pan and the 10554 pump.

I am sure canton has several SBC pans but the 242t which is fbody specific is 5 qt pan according to summit but canton specifies 6 qt system capacity which apparently includes the filter and oil galleys. I am not sure exactly how accurate that is due to differences in filters but I just put 6 qts in and call it a day

i agree some of the pans above are for road race apps vs a street strip pan..

any pass side dip stick sbc pan should work with full kick out or not.

this is the one most use it only clears a 3.8 crank

^each of the first 2 you recommended you would lose ground clearance with. 3/4 of an inch with the first and 1/2 and inch with the second. It might not sound like much but if you only have a few inches of ground clearance to begin with 3/4 of in inch IS a big deal especially on lowered cars.

Some of the Stef's need a bit of clearance for strokers. They are one of the few pans that can fit a titan thou.

I run a Canton, its well made and relatively cheap. As others said the scraper is pathetic but at least there is one.

So what P/N for pickup and pump did you use for a standard setup?

Moroso #20205 , i have great clearance even with LTs. IDK if a Y-pipe would interfere though, Im running TDs. Holds 7 qts. good ground clearance, im stock ride height also

Easiest thing to do is to call the pan manufacturer, supply them the oil pump part number to see if they have a pickup that works with your pump and their pan.

Ditto, I have used this pan on LT1s as well
I used a M55HV and Morosos screen , had 1/2 inch of clearance with gasket.

the pump/pickup ordeal is pretty straight forward. If you buy a pan from a specific manufacturer use the manufacturer's recommended pickup. They will usually have 2 pickups to choose from either a 3/4 or a 5/8 inch pickup. Stock, and melling 55, and melling 55hv are 5/8 inlets. Melling 155 and melling 155hv have 3/4 inch inlets. There are other pumps available with a few more bells and whistles but these are the cheapest and most common.

Here's the exact set of parts that I went with after talking to Canton. I can't speak to the leaking issue as I haven't started the car yet. It looks like a very good quality pan and I didn't have to clearance anything.

Melling Select HV Oil Pump 10551
Canton Oil Pan Pickup 20-023
Canton Road Race Series Wet Sump Oil Pan 15-242T
Canton Oil Pan Plug 20mm x 1.5
