I was the builder... I have hyd. lifters and harland sharp roller rockers and yes I installed .090 restrictors by the advise of geroge anderson at gessford machine.
When my motor is cold the pressure is up around 70lbs. but after it heats up it idles with about 30lbs of pressure then as I give it fuel it climbs to about 50lbs.
Is this OK? I really dont know where the
oil level is but I put in about 9 quarts with my Avaid
oil pan.
