Pertronix---
On my 66 barracuda 273...installed the same...bypassed the resistor as I got the coil with it and it said too....she does start better and idles great. The instructions state to time it after the install..but I don't have a gun yet.
bought the pertronixs from ferd guy on ebay...nice guy from FL.
