Thanks, it's a MSD 6al, timing 20 initial, no vacuum, 30 total. It's steady and I have a bit stiffer springs in it so total comes in at around 2,800. It has a dynamic 9.5" converter that flashes at 4,400 so no real need for timing to come in fast. I'll try the float settings. Was a bit surprised it handles all this carburation, it really rips when the outboards open!
