Clearance also effects psi right? My 283 stays at 80 psi, 80 psi while driving and drops to 60 or more at idle.
Old L6 dodge should be worn out as oil psi drops to nothing with reg oil, we have some 90# in it now but only drive it less than 1500rpm and only about 1 or two miles per year, until I drop the rebuilt one in.
