Do any of you guys run a stock oil pan on your motor? I've heard some different opinions on this. I'm running a 355 chevy. 4 eyebrow pistons. Stock crank,and cast heads.Stock oil pump and hydraulic cam with under .490 lift. If my calculations are correct i should be taching out at around 4800 to 5000 rpm's at the end of the straight. Do you think the stock pan and pump will get me by for awhile????? Your opinions and criticism is appreciated.

OK ARE U STATING STOCK AS IN STOCK OR STOCK APPEARING IF STOCK GO WITH OLD STYLE VETTE PANS THE ARE LONGER LENGTH WISE AND HOLD MORE OIL BUT IF YOU WANT TO SPEND AT LEAST OR ABOUT 100 .00 YOU CAN GO WITH CRP PRODUCTS PAN -CHAMP OR MOROSO AND RUN A M55A PUMP HAVE THEM ON ENGINES TURNING 6500 TO 7000 AND NO TROUBLE

Run an extra Qt of oil and you'll be fine I ran one like that for years never had a prob you should be safe especially with such low RPMs

stock pan for years no problems just like flatlander run it 1 qt over you might want to fire your calculator up tho and find some more rpm's with a 490 cam your not going to be anywhere near the max of your power band

thanks for the replies. if it gets down to crunch time i'll probably run the stock pan on test and tune night, but i'm going to go ahead and get a kick out pan with some doors on it as soon as funds permit. at this point every dollar counts!

this cam says 2200 to 5200 rpms. gearing is not perfect, but i should be real close. not worried .....yet.

Looks like you have all the answers you need, but I thought I would add this, stock pans with an extra qt of oil may cause the crank to hit the oil while turning in the corners. I say that it may cause I wouldn't know what to look for in terms of sounds from the engine. maybe run a lap on test night with 5 qts then 6 qts and see if you notice a RPM diff. But the pans that hold extra oil and have the doors on them can be had fairly inexpensivly anymore. And this, how much did your engine cost? and how much to replace if you spin a bearing? the pan is really cheap insurance. A friend of mine put some of the doors in a stock pan and it seemed to work for him. FYI

I have also run a stock pan with a stock volume pump and use 6 qts. and have not had any problems. It has maintained 80 psi always and I turn mine about6200-6500 rpm with a 480 lift cam.

I ran a stock pan last season after many years running an 8 quart moroso (it came on a during the season emergency engine). It worked fine. I ran a pint extra oil and boy am I glad I did. When my motor was torn down the pickup was laying in the PAN !!! no damage though. WHEW.

About the cheapest insurance here is to use an accumulator. I prefer the vertical type with no working parts, thus nothing to fail. Canton and Moroso have them and they are not expensive. I have made my own from driveshaft tubing or fire extinguisher bottles. Did an article for SCR several years ago using a video camera on the oil pressure gauge. At both ends of the track the pressure dropped from 60 to 3 right at the point of picking up the throttle. With an accumulator in place pressure dropped less than 5 pounds at the same point. This was with a stock pan in a street stock Monte Carlo. SLEEPY

Let me add this,,,Milidon make a nice 5qt stock appearing pan with a dzused in baffle tray. Well worth the money. Order the pick-up to go with it.
