Gents, Looking for a quick bit of advice from those more learned than I. Fresh rebuit small block, started up to run cam in and oil pressure is steady at 50lb. Idle set at 2500. Timing roughed in but pretty close. After about 10mins of fast tick over oil pressure started to drop down to 25lb and stayed there. Temp is around 200. Am I being paranoid over a fresh build or is this an indication of a problem?? Any advice?? Many thanks P.
