Ignition Ballast hot!! and i mean hot!

Hello all and well i have a 74 scamp with a 318...... 600 Edelbrock cfm.........it originally would idle fine until it hit 190 . which is normal operation for my car does not get any hotter.....well it would always die around there when it hit 190 would stumble and fall and die.....timing seems good...so tonite i relocated the coil to the inner fender area bc it was getting way way hot...i also noticed the igniton ballast resistor was super super hot. i let it run for 30 mins did good but the coil still was pretty warm and the ballast resistor ( 4 prong dual) is very hot . just worried that or the coil will break down some how and want to die....any help is appreciated thank u all folks
