Hello, it has been over 3yrs since the car bit the dust with harmonic balancer falling off during a drive (CS bore dammaged with what appears to be a poor attempt to fix a broken bolt). The engine is finally out and off to the machine shop for repair. I have a brand new stock HB and a used stock SC lower pulley I got from ebay that is in good shape. I also have the metco pulley set up which was on the car. The motor is build; stroker, Kenne Bell, headers, cams etc. The original stock SC pulley came apart at the rubber bushings several years ago which is why it had the metco on it. I am not sure how well this used one will hold up so am debating on whether to use it or just put the metco back on it. Any thoughts? Thanks for the input.
