Juice Help

I ran a 150 hp NOS plate system on a #s matching 66 Chevelle SS 396/325 hp car and it was great. 2 very important things are fuel delivery and ignition. You do not want to go lean or have detonation. The more Nos you run the more critical those 2 points are. You want a good fuel pump and an after market spark box would not be a bad idea. I ran a micro switch on my carb to get the flow going.
