I missed you question about oil pumps in my first post. All automotive oil pumps that I have seen,chevy included have a pressure regulator valve built into the pump. There was also the question about welding the oil pickup tube in a chevy pump. This advice is almost manditory on a race engine where the vibration of 8000 rpm will oftem shake the pickup out of the pump. My caution is to weld then quickly cool the weld so you do not heat/weaken the pressure relief spring and cause a low oil presure problem. One other point that pertains to older engines with the old flat tappet camshafts more than the newer ones with roller cams. The camshaft is almost totally lubricated by oil thrown off the crankshaft and rods. an engine with a "loose" bottom end will do a better job of lubricating the cam than a tight one that opens the pump pressure regulator and dumps excess oil back into the pan. This is important on a high performance cam with stiff valve springs.
