what bearings are you running in that brand new 440? OEM style half groove bearings? then yea, standard pump is all you need.

but if you're running full groove bearings that oil the journals all the time instead of just half the time, then an HV would help you out.

my big block is running an HV, and it sees 75psi cold at start up, but warm idle it's around 30. at cruise it's 65.
