Yes, but be sure it's heavy enough to carry the current draw of the HEI ignition system. The 50,000+ volt firing voltage is generated by using a coil with a very low primary winding resistance, usually in the range of 1/2 Ohm or so. Before the internal current limiter in the ignition module kicks in at the magnetic saturation point of the coil, it's possible to draw 20 to 30 amps or so through the primary windings. Make sure the supply wire from the battery to the ignition switch and the wire going from the switch to the coil are heavy enough to carry the current without overloading. There's a reason the GM engineers chose #10 wire for the millions of HEI systems they installed as original equipment from the mid-1970's on up.
