I take a stock volume melling pump, bore the inlet to 3/4 and then use a Milodon pan/pickup and cut the end of the pickup tube off and weld it into the pump making the inlet a true 3/4.
Then bore the outlet to 1/2 and port the main cap. That's about all you need to do for most anything running under 8000rpm.
Make sure you have ample rod and main bearing clearance!

What would you consider ample rod and main bearing clearance?

I've got .001 mains and .0015 rods
 
If using a 90* oil filter adapter, take and smooth the passages removing any all sharp turns/bends.

You can also plug the pass side lifter galley behind the cam plate and run a hard line cross over tube to the driverside.

just my opinion, and I am no engine builder, but thats way too tight on the mains...

I'm going for .0025-.003" on my build.

You know, I don't have my sheet in front of me. My memory might not be right on those mains. I just did the rods on Sunday at .0015
 
Yeah, I can read that just fine.... must be horny...lol
But you still didnt answer what you're doing with it. Drag racing? Street duty? Road/highway racing? Extended rpms? What are the specifics of the build? Cam? crank type, etc?

building stroker now like to build roller cam motor
need good oiling system one shot on this build WHAT IS THE BEST OILING SYSTEM AND PARTS FOR VALVE TRAIN
ROLLER ROCKERS OR STEEL,ROLLER LIFTERS
FOR SMALL BLOCK 340 BORE TUBE BYPASS RESTRICT ????????
would to be hard on the car when i can some track some street mainly show
but love to race pro sport on some week ends
20 years to much time and money has to go fast
 
yeah debur the cap and bore the pump and install the large pickup as previous stated.
the crossover is a good idea too and that should be it. make sure everthiing is nice and smooth, no sharp edges. windage tray and baffle in pan. I once tried to think of a way to enclose the cam tunnel and have the oil drain into the pan in the front and back but still working on that. Some run full groove mains.(using two top bearing shell in each location) I dont like the idea though. Most important has been stated, the larger pickup, not one that has been "necked down" to fit in the stock threaded opening. My .02

I typically shoot for .0025 rods and .003 on the mains for street performance and more for racing.
I've used .0035 on the rods and .004 on the mains in applications that need it. THAT's when you need VOLUME!!
 
For show and go with a roller cam? Bush the lifter bores, make sure the oil feeds from the cam journals to the mains are enlarged to 9/32 or 5/16s, make sure the filter plate has 8 holes or more, if you run the 90° adaptor you can clean up the edges as the posts above note, drill a couple extra drain back holes in the valley and debur the edges of the valley drains. Otherwise, make sure the clearances are in spec, run the HP spring in a std oil pump, and have fun. No reason to do much else.
 
the drilling extra holes in the filter plate has always made no sense to me at all.
the return is only so big, all the existing holes in the plate if made into 1 would already be larger than the return.
all it does is weaken the plate.imo
 
Yeah, I've never seen any testing that said it was really helpful. But I see a plate with a few holes vs the older ones with many more, I figure I'll drill them and invest the time the factory decided not to. As far as weakening the plate.... I suppose it does. But not to any degree that would affect anything.
