I replaced my unit with an aftermarket HEI from Mallory. The instructions say to install a ballast resistor if you don't have a resistor built into the wiring harness. My old stock HEI did not as Atomarc and others have said. If the carb is new you need a 0-30" Hg. vacuum gauge to get the adjustments right.
