you wrote centerline; the math says these are the LSAs, Lobe Separation Angles. Have I got that right? If yes then,
the 5.2 is in at 110/3* advanced which is normal, and
the 5.9 is in at 104.5/4.5* advanced also normal.
I will update my notes
But you know what the Ica's come to with these installs? I get 55 on the 5.2, and 40 and friggen 9, on the 5.9. These numbers, in 9.2Scr engines, are predicted to make 163/164 psi cylinder pressure. That's supposed to require 91 gas..........
I ran my 1992 on 87 and never heard a peep from it.No wonder she was peppy
Edit; These Ica's are when installed at split overlap , not the factory installs of 115 and117 as posted byTT5.9mag.
Those numbers drop the pressure right into 87 octane territory
