The flow rating doesn't matter as long as the pump you use can meet or
exceed it. As for pressure, yes, this can make a big difference. I would
use a pump that exceeds the 39psi, and then use an adjustable regulator
to take it down to the 39psi you need. Just for an example, you could
use the pump you mentioned and then an Accel adjustable regulator and
use a guage to set it.

Better might be to just use a GM pump/regulator from a 1985 350 TPI, as
these are 39psi... better check that to make sure. I think the Frod 5.0L
uses a 39psi system as well. Junk yard might be a cheap and easy route
on those items.
