This week il try to mess with the timing. I'll put the stock spring back in the distributor (it currently has one stock spring and one light spring). It's supposed to have 2 medium springs. I also found that the distributer gets 15 lbs of pressure at vacuum advance (1500 rpms). I will bring the total down a little bit with the adjustable vacuum advance. Il keep the initial around 6-8. Thanks for the information everyone.
