High Volume Oil Pump?

My machine shop told me a 5 quart oil pan would be ok with a HV oil pump provided I don't get out on the highway and go wide open throttle over 100 mph for like 10 minutes straight. You should be fine running 5 quarts unless you plan to rev over 7,000 rpm all the time.

If you run more oil then the pan holds the crank may splash it too much causing the oil to foam up then you'll have a problem.
