Re: Part Number BBC Radiator Hose?
Thanks Daryl... The original GM part number IS 3946039 TH. I need a spare to mess with, will check with NAPA or one of the other local AZone or Advanced... Gates cross-reference is #20470 but I think (?) that this is one of those cut to fit deals regardless of which brand it is. My hose pretty much has one bend just past where the radiator neck is. A lot of the "correct" hoses have a second bend... like the motor is 6" further away.
