What are the advantages of running additional oil capacity pans in a Pontiac race only engine? My thinking is , if you're only running 1/8 & 1/4 miles, would a stock 6 quart pan be enough,? Thanks. Roger

It depends on engine drain back capability during that 1/4th mile blast.
1/8th mile probably would never have an issue.

I would absolutely not run a stock Pontiac pan on a race only engine. A stock pan and pickup has between a 1/2 and 3/4 of a quart below the pick up. A larger style race oil filter will hold the better part of a quart. The oil pumped throughout the engine along with oil in suspension at RPM, and some amount trying to return account for some X amount depending on application. Combine all those factors along with the oil climbing the back of the pan on launch, and acceleration, and you're on the ragged edge capacity wise. A extra capacity pan such as a Canton, or Steff's is a great investment IMO.

On a related topic, what is the capacity of a Canton 400 pan with a K&N 2003 filter? 6.5 or 7 Quarts ? I run 7 Qts.

Note it will probably state a 6 qt System Capacity.

When I called Canton and asked about their statement "6 qt System Capacity" I was told at the time by a Canton Tech person it is meant that it was 5 quarts for the pan itself and they allowed 1 quart for a oil filter. A total of 6 quarts.

Others disagree regarding that statement. Some have suggested measuring the pan itself it could be slightly different. Also note most common Pontiac oil filters do not hold 1 quart oil.

Fill yours, let it soak up the oil. Tap it, then do it again a few times. A NAPA 1049 holds about 3/4 quart.

Do you run a remote filter set up.....

Calculating the amount of oil inside the lines to and from the remote filter and inside the filter itself is always a good idea.

My remote filter lines have about 1/4 quart inside them.

So a stated 6.5 capacity would be 5.5 plus the filter?? I have no remote lines or filters..maybe I'm about 1/2 quart over.

It depends. How high a RPM are you running ? How much power are you trying to make ?

I have ran a stock oil pan on a 10 second 455 for years and years and never hurt it. But I was shifting at 5500RPM and crossing the line at 6200 on a good run. But higher on a bad run if I shifted out of 1-2 late.
I do think it is even baffled. Might be, its been a long time since I had it off.
But yes, if you are serious get a good pan. My Steffs is full at 7 1/2 quarts on new engine.
I never sucked the old pan dry at 6 quarts or had a issue with 1.43 60 foots on the starting line. Iron heads with good drain-back, but if I had a early set of E heads might have had a problem.

Engine has Ist gen E heads with good massaged oil drain back. Moroso 7 qt. pan( I'm guessing that includes 1 quart in the filter). Engine will be shifted around 56-5800. I've read somewhere I could run 6 quarts of oil in a 7 quart system, keeping oil away from the crank. I'm also running a Moroso windage tray and scraper. Just don't want to starve the 3.25 journals. Engine will mostly see 1/8 mile passes,

Start making enough power to yank the front tires a foof off the ground at lunch and if you don’t have 6 qts just in a baffled pan, then even 1/8 mile runs can be expensive!

I run 7 qts. on my 400 pan. I use a factory dipstick and tube. 7 Qts puts it at the add line on the factory stick. So, even at 7 qts, the oil is further away from the crank than a factory pan.

Thanks! Confirms what I was thinking.

I run the Canton pan with 7 liters.
