Max is likely to be 80-90 lbs depending on your bearing clearances. That's a bit high for my taste. I'd suggest going back to the stock pump if possible as it's more the adequate for most situations. I recently dynoed a similar setup and the pressure touched 100. Back to the stock pump and max is now about 65.
I tend to agree with NealM. Unless you have large bearing clearances in a 'low friction' race engine there is no need for a high volume or high pressure pump. You are just putting a lot of unneccessary load on the oil pump drive shaft and cam gear on the distirbutor. If you search here you will find more than one thread describing oil pump driveshaft or distributor gear failures that were probably compounded by the oil pump selection. I'd be happy with 60 PSI max pressure. I have a stock pump in mine and it idles at about 35 PSI hot and maxes out at about 65PSI hot at high RPM's.
80 psi cold... 50+ psi hot. I would not want more than 80 psi cold or less than 30 psi hot, personally.
