    Tech note from Comp cams VVT tech bulletin. The difference in the pin between 156 and 189 cores equates to 13 degrees cam retard (if a 156 is used
    where a 189 is required). {thinking i have a 156 "type" core installed and with only 7 degrees of advance available in the phaser I am not going to be able to make up the 13 degree difference... Looks like I won't need to call Allen..
    Vvt is garbage.
