working on a 1971 cuda with a 431 stroked 383, it has MSD, holley red electric pump, classic air just installed and dual electric fans. The problem is running the air, it drains the battery dead.
Not sure what amp alternator i need, but i know it has to be more than the 60 amp unit thats on it now.

( it takes a Mopar, to beat a Mopar!
