Sorry, I did not and the car is now laid up for the winter. I'd be glad to do it in the Spring if you remind me.
Have you checked the pump impellor clearance? Pump output drops off very dramatically with even small increases in clearance. The 1937/38 shop manual for the Super Eight which uses essentially the same pump calls for a clearance of 0.010" to 0.034" between the pump body and impellor.
Also important to pump flow volume is the pump to block gasket dimension which sets the rear clearance of the impellor. Gasket (copper ring) should be 0.025".
