I would go with a standard oil pump. I have a Melling hv in the 302 I built in 00, and with decent clearances, it pegs the stock gage when cold, and when hot, it is still 3/4 the way up the scale. I actually quit running 10w40 and went to 10w30 to lower this. This is with Motorcraft semisythetic oil.
I put a standard pump in a sbc cheapo rebuild I did last year, checked the clearances with plastigage and Bud Light Lime, and it still has 60 psi down the road and 30 at idle, hot, with the cheapest parts store 10w30 you can get.
