Locked out for sure. Deleted, I don't know. I think BTR said a delete would send them 8.5 degrees advance. That's kind of a lot, and a lot of top end range to give up. People refer to the 220 as the "baby" cam but it's got a lot of lift and fair amount of duration for a baby. I don't know enough about the G5 LT1 to know how much slack there is in PTV before enough is enough. At least the LT's have reliefs, I think previous Gens were dished?
