Is that not a pair of exhaust camshafts I'm looking at or am I going mad?!
Also, there is not a lot of duration on those lobes. My Piper 285 and even my QED 42Hs have a lot blunter looking profile but fatter, more bulbous lobe. They look like standard GM items from that photo but perhaps that's a bit harsh.
I've asked for a picture of the end stamps that QED put into them but not had a response....................
Any thoughts on them?
