High Volume vs Standard Volume Oil Pump

I have had lifters collapse and oil pressure drop down to nothing under hard acceleration in a 340 w HV pump and stock pan turning 7200. Dont believe pan was pumped dry, but oil deff was not at the pick up. A few episodes of that and I spun a rod bearing. Therefor I personally will never use a HV pump again w a stock pan. Probably would have lived much longer if I had not turned it over 6500. Running a kevko pan 2nd time around and am having no oiling issues up to 7500.
