high volume oil pump
It's probably a good idea. However somebody once told me the problem with high volume is the fact that the valve covers can get filled with oil from the sump and leaving it critically low in oil. The problem: the oil will follow the path of least resistance and thats through the valve train and the oil passage returns from the heads are too small. The solution is to place an oil restrictor to each of the oil supplies to each head. This is a drop in washer like device that goes under under the rocker arm support pedestal that supplies oil to each head. That decreases the hole oil diameter, thus decreasing flow....at least in theory. Not really too sure where to get these or if they are a homemade item. Good luck

high volume oil pump
it's a 360. my parts guy is going to order a couple of different sized main bearings i'm going to replace the mains, he said they make a high volume and a high pressure pump, different pumps from what he says. so i'm thinking of putting in a high pressure pump when i do the mains, any thoughts?

high volume oil pump
You need to have the oiling system modified. Drill the passage from the oil filter adapter to the oil pump out to 7/16" and use a high volume oil pump. Some people choose to use oil restrictors under the rocker shaft stand to prevent filling of the valve covers. Also fill the pan to 6 quarts instead of 5. This will not leave the crank spinning in oil so don't worry.

Some of the bearing manufacturers make undersized bearings. Since you are considering removing your oil pan anyway to install the pump, have you thought about putting new bearings in the rods and mains?
You would not have to pull the crank to do it.

high volume oil pump
KurtWolf, tell your parts guy to hold off awhile. You may not need new mains. If they aren't spun and they are quiet, leave them alone. Even if you have .003-.0045 clearance, they'll be okay. How much pressure do you have at idle ? If you are going to remove the pan, by all means put a bigger pump in it. A mellings M57HV is the one you need. A better pump drive would be cheap insurance against problems. And replacing a pump and drive is a whole lot easier than doing the mains with the crank in. It isn't that you can't do it, but it may be a whole lot more work than you really need. The FE series has a few issues that could be addressed that would help you a bunch more than new mains would. How about jumping over to the FE section and we'll talk about it. DF
