Does anyone have the original specs for a 1980-84 (non roller) vin Y cam?
I'm sure they are pretty dismal, but I haven't been able to locate that information. I've found specs on OE replacement cams, but I have no idea whether those are the same or not. Thanks!

 

Almost identical to the 196/198? .400/.402, 350 and 403 cam. I Think the 307 Y cam is 195/196 .398/.400 or very close to that.
