Took my car out for practice. 77 monte basically stock 350 sbc on a medium to high banked 1/4 mile track. Coming off the turns and down the straights i had barley any oil pressure. i'm using SAE40 oil. could the oil be to thick where the pump cant pick it up? or do i have another problem? Thanks

is the pick up still on??

do you have enough oil?

that oil is not too thick..

could be loose clearances, lots of things. is it a new motor?

stock pan? name brand gauge? i'ld find the problem before i ran it again. have you checked the clearence from the bottom of your pick up to the bottom of your pan? first thing i would do after checking the guage and sending unit or line is get that oil pan off and have a look. god luck! p.s. was your car warmed up or was the oil still pretty cold?

I guess i'll pull the pan later today. the car was warmed up for about 15 to 20 minutes so i dont think the engine was cold. Thanks

if you have a hydraulic cam, .002" lash works nice. snaps the valve open and helps the car come off the corner better....also keeps the lifters from "pumping up". if you're running a solid or roller cam, follow the manufacturers specs.

sure could do a search on here for oil filters you'll see we have all come to the conclusion that fram is a silent motor killer

Get the right pan for the application. A $68 claimer pan may work for a little while, but when you have to replace the mains you have not saved any money.

Buy a pan that is made for racing.

Even if you only have a $2000 motor, what is $140 to make sure it stays together?

Dont run a high vol pump with a stock pan , it will pump it dry. I run 50w oil and an accumulator. Pick up height should be between 1/4 & 3/8. Check out the distributor gear, it runs the pump. Make sure the 1/4 " press in plug went in under the rear main cap, without it the engine will have a internal oil leak.
