[Walt Fricke]

That's a nice tool kit, but I'd not purchase it until I had removed at least one chain box cover, and looked at the end of the cam. While Pelican assumes that SCs of that vintage have the chain gear held on with a bolt (which is why they include the cam holder with a cylindrical end with some round rods sticking out), my '82 engine came to me used with the earlier "big nut" (46mm) cam, which requires a different cam holder in addition to a 46mm crow's foot. I had no reason to believe the engine had ever been apart. The two cams are identical in terms of their lobes, just the end is different. Porsche sometimes dealt with temporary shortages by using earlier parts.
