I'm new to the site and have a couple of question's maybe someone could help me out with, I have a 67 GS 340 with a freshly rebuilt 1970 455 with a slight Comp Cam installed. I will be starting the motor for the first time and was wondering about some setting's basic stuff, I will be using a MSD ready to run Distributor with a blaster II coil, should I run Vac and Mech advance or just Mech ? also what type of setting's should I dial in in advance in the way of Dist setup. Spark plug gap what would be the best recomendation on this both the 67 and 70 info I have are for points setup should I use a larger gap.
Intial Timing setting.
Sorry for the basic stuff but I have been out of the game for 10 plus years.
