Here is a video of a mid 10 run with an "essentially" unmodified oiling system in my 408 solid lifter motor. Hi volume pump, 1/2" pickup running full synthetic 10-40 Royal purple. Oil press. gauge is just to the right of the steering wheel. 200 degree oil @ idle is around 30 psi on the gauge, so the engine had to be a little on the cool side on this run as oil press. @ launch was around 40 psi. End of run was about 7K and oil press. around 90psi.
