I feel Mallory is the quietest electric pump you can get. Depending on what is done to the engine, I would think a 140 gph can handle a mild street engine easily. If you are interested I have a 250 GPH Mallory that I took out of my car for sale. It worked fine with my 468.
Currently running an old Holley red pump with no issues on my 502. I have a new Aeromotive 150gph pump waiting to go in when I rewire the car sometime in the near future. Ran the Aeromotive for a year on my old jet boat (500hp 474ci BBF) and never had an issue with it (which is why I bought the same pump for my Nova).
