Start by disconnecting the negative battery terminal, followed by removing the distributor cap and noting the rotor's position. Install the new distributor by aligning the rotor with the correct cylinder. Secure it, reattach the pigtail harness, and finally reconnect the battery. Detailed instructions are usually included with the product to guide through the process.

    Answer: The MAS HEI Ignition Distributor package typically includes the distributor itself, a tachometer pigtail harness for connection to your tachometer, and potentially other hardware necessary for installation, such as mounting hardware or gaskets.
