cool what kind of coil would be good to use i want to go bigger but how big? one of my chevy frends had an accel big yellow coil on his 350 and it ran like krap then he asked the shop teacher and he said your coils to hot for your wires and he went smaller and it was fine so that got me woried
I gotta call bull S#!T on that one; your teacher was wrong there. if it changed how well it ran, just by changing the coil, your buddy either had a defective coil, or possibly something hooked up wrong and was "corrected" in unhooking and re hooking the replacement coil. I don't care how big your coil is; it never puts out max rated output, unless called for! Have you guys been thru a unit on the engine scope yet? If you ever get to see a firing pattern, you will see that an ignition sys in good shape will actually only put out ~5-6KV NOT 45KV. The HEI that has been stock on gajillions of GM products since about 1975 is rated @ like 50KV; I think that some systems were rated @ 80KV; but they did not actually put out any where near that unless the plugs were about burned out. That was why they increased the plug gap from 0.035 to 0.045, and in some cases as much as 0.080" because their ign, systems had the CAPABILITY to put out that much juice, but again, even at 0.080" gap they never had a need to PRODUCE that amount of energy. It's like water, path of least resistance.
Also like an alternator; 125 amp units are common these days; but if there is only 35 amps being drawn, the alternator will only put out, 35 amps. If it put out 125 amps (rated capacity) without having the actual need, something will fry.
