This HEI unit I bought is new and not a salvage yard unit. Hopefully it will be reliable. I thank you all for your inputs and I will be installing the unit in a few days, hopefully. I am in the middle of a rear brake overhaul right now. wheel cylinders, flex hose at the differential and most likely a rebuilt Master cylinder.
