Reuse the bearings....no dice on the hv pump. Not fun w a stock pan and hv pump to look down bout half way through 2nd and not have any OP. YRMV
Ridge ream it, hone, rings and hammer down...

If there is any ridge at all you can and probably will do damage to the rings. Imagine a brand new ring slamming against it.
I thought about that too, however I had no problems when I threw a new set of rings in my 76 440.

I have no idea why the high volume pump idea wont die. With new bearings recommended at the same time no less. Because he's slapping new bearings on worn out journals. This is the application hv pumps were intended for. If anything new bearing on a worn journal would potentially restore some clearance, not make it worse. Everyone puts on a Hi Volume pump because that is the hi performance thing to do. It will suck a 4qt sump pan dry that is low on oil

They do more harm than good and rob horsepower too.

Why would you use a stock pan? Budget build. But I am trying to sell or trade my 699 pan to get at least seven quart for mine

Why would you use a stock pan? Budget build. But I am trying to sell or trade my 699 pan to get at least seven quart for mine The phrase if it ain't broke don't fix it comes to mind here. You are doing a basic stock spec rebuild here with some minor bolt on improvements. A couple of DIY mods to that stock pan to keep the oil in the sump is all it needs. As for the HV pump, not likely needed. Here's a test. Use the original pump (after inspection) and make note of your hot oil pressure. It should be in the 55-65 psi range throttled up which is lots for an engine that won't see over 6000 RPM. Pull the relief spring out and shim it with a flat washer. If your hot oil pressure is now higher, the regular volume pump is able to supply more oil than you need. If it isn't, then the cam bearings are likely worn out. On a low buck engine the easy way to crutch this up is a HV pump. Kevin

If this engine is for a street car, I would use nothing else but a HV oil pump...
If for nothing else, the cooling capability...
Been running one for many years on a street car...
Temp is the enemy on a car that's gonna see extended running time... Generating higher pressure and running unneeded oil thru the bypass actually generates more heat. Kevin

Why would you use a stock pan? Because the car is stock looking and a pan that drags on the street if you look at a pothole crosseyed is not an option.

HV... Higher VOLUME... Not pressure... But if one does nothing to increase the flow a hi volume pump does nothing but cycle the excess volume thru the return ... creating heat ... and RAISES the pressure ... because pressure is a restriction to flow ...

This is the application hv pumps were intended for. No, that isnt what a hv pump was ever for. New bearings should bring up the pressure with a standard pump. I wouldnt bother changing them unless they were real bad anyway. At that point you'd likely want to polish or cut the journals, which also raises pressure. A hv pump is a crutch for a trashed, ragged out engine. Thinking new bearings go hand in hand with one is wrong.
