340 cam timing, 1.6 rockers?

That cam sure is low lift......even calculating 1.6 rockers. Makes me wonder which one it could be. Erson made a line of low lift cams like that. Some of them got pretty nasty on the duration side. Have you taken the cam out yet? Maybe look on the back and see if there are some numbers on it.

I didn’t pull the cam out. Wishing I did before I re-sealed everything up and painted the engine. It always ran great, gave passengers whiplash, cylinders looked like they just left the machine shop, cam didn’t look wiped out. So I figured, don’t fix what ain’t broke and closed it back up. I did find that 2 cylinders had the rockers installed wrong so they had a bad wear pattern on them. So I needed to replace the rockers, which lead me down the hole of just getting some better heads. Funny how these things happen.

You really think I should tear it back open to see if it has some grind numbers on it?
