How did a milidon 30401 pan become a stock replacement?
 

Bigger, Deeper, and oil further from the crank. Can the person approving this stuff read a ruler, scales or digital calipers. Reading the vernier on a micrometer maybe out of the question. When was the last time the NHRA tools got checked against a National Standard? How many SBC oil pans are painted black?

Re: How did a milidon 30401 pan become a stock replacement?
 

Larry, not a good idea to POKE the Bear. When you find out the answer to your question, please find out how the 66 Chevy novas got a deep sump pan also ….

Reading a ruler?

Re: How did a milidon 30401 pan become a stock replacement?
 

Cost me an engine, because we didn't check it out. Turns out to be a much larger pan than 5 quarts. And it's in the approved parts list

Re: How did a milidon 30401 pan become a stock replacement?
 

That thing is so deep you will have to put 12 quarts or more in it to slow your ol 350 down. LOL

Re: How did a milidon 30401 pan become a stock replacement?
 

The COPO, Drag Pack, and the factory Cobra Jet are all built from catalogs at custom shops. I do not have a problem with that
It is the stuff that is a direct replacement that is way wrong. The comparison is very similar to Larry Hodge and myself. We are both old racers but that is where the similarities end, but we have the same initials. He is regular size and I am slightly bigger by at least three quarts. One Larry is not a direct replacement for the other one.

During having a piston approved I had to supply an OEM piston and my preposed accepted replacement all on my dime. Weight, ring lands placements, compression height, valve notch cc, wrist pin size, and appearance of the top of the piston. To do all of that it took NHRA some time and skill.

My next question is what happened?

Did the acceptance process turn into an income steam for NHRA or did they just lost sight of fairness to the racers.

Re: How did a milidon 30401 pan become a stock replacement?
 

any oil pan can be extra deep... if you drain enough oil out LOL

Re: How did a milidon 30401 pan become a stock replacement?
 

The Milodon 30401 is a copy of the 6 qt Chevy Corvette SBC oil pan. 5 in the pan and 1 in the filter.
Moroso has an equivalent to the pan under P/N 20180 and it is also NHRA approved.
Both pans have been approved as a replacement to the OEM 5 qt oil pan.

Should NHRA ban the use of oil accumulators too?

Re: How did a milidon 30401 pan become a stock replacement?
 

Any companies pay oil pan contingency?

Re: How did a milidon 30401 pan become a stock replacement?
 

After you guys figure out the oil pan you may want to look into how 396/375 Camaros (just one popular example we all know there’s many more :) )can run 9.50’s at 3600 pounds stock ! Lol I think the least of anyones worries are an oil pan at this point . This class is out of control lol ! No tech, no tear down , but get that fuel checked after a qualifying run lmao!!!!!!

Re: How did a milidon 30401 pan become a stock replacement?
 

Since the oil pans are allowed to be bigger two or three quarts, it would probably be ok to increase runner volume 25cc or valve size .040 on diameter, or make the head 10cc smaller.

Re: How did a milidon 30401 pan become a stock replacement?
 

Hyperbole much???




No insult intended, but, seriously, with all of the utterly egregious stuff in Stock, you REALLY want to worry about THAT oil pan?

Re: How did a milidon 30401 pan become a stock replacement?
 

Larry

You must be Wineing to get HP off your combo, hit speed dial for Pat's Number

Re: How did a milidon 30401 pan become a stock replacement?
 

The truth is that having a bigger pan does not mean you will be gaining additional power. You make more power by controlling the movement of the oil inside the pan and diminishing windage.
