Guys I am thinking about replacing my coil, I had the stock one but, I think it went bad, so I replced it with an accel that I had used, I wan to know wich one will work better,electricaly,
GM stock or the accel on a LT1

 

should work about the same. The coil will put out only what it needs to. If your running lean it'll produce more voltage, if your running rich it'll produce less. Accel may reach full saturation faster, but I dont see any major performance advantages.
