340 oil pump

Hey guys. I'm building a 340 based 373 ci engine and need some direction on which oil pump to use. It will be street driven except with a few dragstrip passes a year. The car is a 67 barracuda with a 904 shifting at about 5700 rpm. Should I use a stock pump which runs about 50 psi, or high volume. How about a high pressure relief spring on a stock pump? Thanks, Bob
