I think all Mustang 289 Hipo's between the years 1965-67 used the same cam (C3OZ-)??? I'm looking for valve lift using the 1.6 ratio on the rockers and duration at 0.05". So far, I found lift at 0.477" on both I and E? - please confirm. Duration at 305 degrees(?) - (what does this translate to at 0.05"?).
