Not sure which cam I have. After 2 failed reground cams in the early 80's when new cams were not available, I bought a rebuilt sprint 6 for parts and swapped the cam and cover as a complete unit. It is an original low mileage cam showing virtually no wear. Only problem was the cam cover had been painted blue and my 6 is red like the car. Looked a little sick until I got in there with a drill and wire wheel to get the cover back to mildly polished aluminum and then highlighted with black on the "fins". Now she runs like a top. We are going to pull the cam later this spring (when the 326 coupe is done) to replace valve seals, check for wear and clean the blue paint I couldn't get to. I'll see if I can find out which cam I have then.
