Pressure question
I have a 71 302 the mileage is unknown. Its very cold today and I just put a mechanical oil guage in the truck because the oil "idiot" light was coming on. I'm not sure what the oil pressure should read at idle when the engine is warm right now it is at 18-20 and jumps on up when I accelerate to around 35. Is this within the normal range?

Thanks

the rule of thumb is 10# per 1000 rpm, so even though the idle pressure isn't high it's adequate as is 35 lbs at higher rpm.
