Trying to open up some shelving space in my shop and I have 2 new small block purple shaft hydralic lifter cams from many many years ago with lifters. Of coarse the boxes are long gone so now I need to ID them. one has the numbers 970407 (I think its a 9) and the other one only has 1138 cast into the cam body. Not worth sending these to have them profiled but do you guys know any tricks??? Pretty sure I had one of these in an engine and degreed it in with my Son Matt 10 years or so ago but we ended up not using the engine. i think that one was a 510 lift cam.
