I just installed a Lares 974 steering box in my 75 Firebird 455. (2-1/2 turns lock to lock). Pretty uneventful R&R. After bleeding the system (no bubbles), and taking it for a test drive I noticed that there is much harder steering effort required at idle. When backing into the garage it feels like close to no power assist. It is using the original Saginaw pump.
Is this a low pressure issue? Is there some modification needed to get the assist up at low RPMs?
FYI: This is the car
