More oil pumps

[airemdwn]

I have a stock melling M55a Oil pump with some miles on it and a high volume- standard pressure oil pump with a few less miles on it, and finally a standard M55a pump with a high pressure spring in it, new.
I run an oil cooler, stock filter and run TBI.
What is my best choice for a new crate 350?

The bone stock M55 is all you need. Chevy's don't need high volume or high pressure.
