I wasnt going to post on this subject any more until Carl posted, but I thought why not just one more. Carl is correct, the SBC does not bypass too the pan. It bypasses within itself, that is one reason you dont want the bypass valve to continually open. It by passes withion itself and builds heat. I, just like Carl, have drilled my on relief hole in the pump so that it will bleed back to the pump. Smokey unit showed me that several, several years ago. The reason, from what I understand, that Melling and other companies came out with HV pumps was to move more oil at the low rpm ban. If you go thru their catalog, you will notice that their HV pump does not make as much pressure. They have a pump called HP to do that. Several years ago, I mounted a remote oil filter with a flow meter mounted in the line. I changed the pumps from standard to HP to HV to Select. If the clearances were ok, There was no more oil going thru the engine, UNLESS you change the pressure. If you up the pressure, then it did flow more oil. It only had more capacity to do so if need. The pulsations WAS slightly lower on the HV. I, just as Carl, now use the 10% HV. Oh yes ED, I, like you, have been doing this since the early 60's. And I think I am too old to see something new, but damn I learn something every time I fire the dyno every day. So Ed, you and I are on the right path to still learn. If you learn something new today, call me. I dont want to miss out on anything. I have to keep notes now though. Book is getting full. I crashed my PC other day and I thought I was really screwed, cause my notes was on it. Then my grandson said, dont worry pops, I backed it up in the sky. So guess he has a direct line to the man upstairs or something like that. I told him to write him a letter and get my notes back. He said I would have them this week end. Now that is service my man.
