Power steering whine/lack of assist question
Hello and thank you for reading
My rod is a '45 Ford 1/2 ton truck. Power by a small block RamJet engine. I've installed a Vintage Air Frontrunner serpentine belt system using a GM type II power steering. I've equipped the truck with a Mustang II type front steering and suspension. Ever since I started this truck the power steering whines badly as I turn the wheel rolling or not. I also don't feel as though it's getting as much assist to the steering as I think it should have. There is no air in the system, nor any leaks. I recall a valve modification done to the earlier types of GM pumps internal pressure vavle but am not sure it that is what needs to be done to this type II pump.
I'm hoping someone might have a suggestion for me to look into.
Thanks for your time.
