is a pain in the ass to locate... I am trying to put my 383 together but I can't locate a new cam thrust bearing. I threw the old one out knowing I would not want to reuse it and now I can't locate a replacement. Dealership just shows the retainer plate(the thrust bearing is a torrington bearing between the retainer plate and the camshaft) and can't garauntee me that the plate will come with the bearing. SWEET. been to a GMC and a Chevy dealer, neither has it(one wanted $10 more to order the retainer plate). The first place knew exactly what I meant(the retainer anyway). So has anyone torn down a roller motor? Do you remember a thrust bearing between the cam and retainer plate or am I being crazy? I swear I remember one, hell I can picture it, but I've torn apart numerous transmissions with torrington bearings in them since then so I could be crossing up memories to fit what I "want" to be seeing. I need to figure this out, I can't put my timing cover on or my oil pan until I figure out if I need this bearing or what.
