So the engine is out the block is at the machine shop and I am cleaning up all the parts. Knowing the oil is the engines life’s blood I want to put in a good pump. If possible a high volume pump any recommendations would be appreciated. Thanks in advance

From what I have read here, a high volume pump is not recommended if the car is for street use.

HIgh volume is definitely not needed and there is also no such thing for a Y, unless you make it.
Precision Oil Pumps blueprint new Melling spur gear pumps and that might be about it as far as any "performance" pump goes. The other options are simply a new Melling pump or to rebuild a Ford spur gear or gerotor pump.

Generally high volume oil pumps are for racing engines with "loose bearing" tolerances shall we say..

As Paul 2748 mentions, a special pump is not needed, especially for street use. You need a good condition pump. Ted E. prefers not to use the older gear style pumps, but other than that, he uses basically stock pumps even for competion!. It's one of the Y-Block's strongest points.. And just a historical note, the Y-Block setup is the "original side oiler"..

There are two basic oil pump styles for the Ford Y. The 1954 Ford and Mercury Y engines were introduced with a spur gear pump that had a cast iron housing. During the 1956 model year, the 312 engines started receiving the gerotor pump that utilizes an aluminum housing. By 1957 all the Ford Y’s are using the gerotor style of pump and this continued through the end of the Y’s production run. Comes 1958, Ford introduces two new engine designs (FE & M-E-L) and these are also utilizing the gerotor style of pump. Many years later, the gerotor pump style is now an industry standard for all engines.
To complicate the oil pump availability for the Y, the aftermarket companies only produce the spur gear style of pump which is simply less expensive to manufacture. Hence the reasoning why the GM engines used that pump style for as long as they did. Rebuild kits for the Ford Y-Block gerotor pumps are still available so rebuilding those older aluminum pumps is still a viable option.
Here are links to some of the various discussions involving oil pumps.
