I too am running N/A style timing with vacuum advance and pulling degrees with MSD 7531. I also have 7.8:1 CR even though the MSD has 10 degs start retard. I've found with low boost, low compression and high cfm the car seems very responsive and torquey. I can't help wondering what is would nave been like at 9.5:1!!!
