I have a mopar perf distrib in it with no points and a flame thrower coil. As for exactly what it does is it starts easy and idles great. As I accelarate it seems like I am driving into a very strong wind and when I get up to speed and hold at a steady speed the car seems to surge or miss I am having a haed time telling. I pulled all the wires and plugs this morning and everything looks great but as I said I had the timoing right at 10*BTDC abd now moved it to 6* but have not driven yet. I will try m oving it to 20*BTDC and try that, do you agree?
