Im not sure if it has been said but if the ignition is in fact controlled by the Haltech (there is a good chance of this) it is IMPERATIVE that the ignition timing be reset properly which requires connecting a laptop to the Haltech and turning on some settings. The distributor will also have the vacuum advance locked out as the Haltech controls this. These are great systems and is what I was running on my car with the old motor.
