Orange or Chrome box??

The four pin HEI modules functionality is no different than that Standard LX101 you are using. To just swap out the module will not get you anything and in fact when mated with a stock mopar coil and ballast resistor has less rpm range that the stock factory ignition. Also, just swapping the module doesn't elminate the need for a ballast resistor as many of the postings on the web claim. It will work but so will elminating the ballast from a mopar system, it's just a matter of how long before the excessive heat generated in the coil results in failure.

To get an advantage you need to use an HEI coil with the module.
