From reading the older posts by Cliff and Ken Ace Brewer on the crower cams they all require 4 to 6 degrees advance just to come in on the installed icl. I think some people without good performance results probably installed theres straight up and ended up 4 to 6 degrees retarded.I dont understand why crower cams are this way as most others arent. I am probably going to upgrade to a 60310 from crane 278 and will go with the 4 degrees advance because i have no access to a degreeing wheel and help.
