Question about Oil presure on a 350 sb???
I have a newly rebuilt 350 smallblock with a high volume oil pump. I was just wondering how much should the oil presure be when it is in gear, I know as it gets warmer it will drop some cause of it getting hot,and plus it aint broke in all that good yet. In my old moter it stayed around 20 when it was hot . my motor now runs around 40 now, but today the temp gauge was running around 170 and the oil presure droped to around 35-40. how low is to low??? im not worried about it, but would like to ask ya'll advice. My gear is 411 so im running around 3000-335000 rpm going down the road. thanks
