I wasn't going to buy a degree wheel even though I am intrigued by the process and the science of it. But I decided to remove the timing cover from engine #3 to replace the old fiber cam gear. Engines video: I found that it has already been replaced (bonus) and upon pulling the cam, I discovered that it has no factory markings. So I measured the lift of all lobes and they are all consistently .300. This makes me wonder about duration and lobe separation. So I bought the degree wheel on ebay. Judging by the condition of the package I think I got a really old wheel. It included a window decal that requires water like the old days. Ill include a couple of pictures.
