I understand there are "restrictors" that can do what Bruce is describing. Plugs with small holes in them to change the bleeding in the
oil system.
I am not completely informed on the Big Blocks, but the 351 Boss/Cleveland has
oil bleeding problems that can be fixed with the addition of restrictors. I did this on my block.
First time I used the .060 restrictors. The second time I used the .125 and got the results I wanted.
You may want to look into this, I think Bruce has a point.
BTW, my
oil runs about 30 to 40 at idle and over 80 at 3500 plus.
