Mopar Forums - Need help with my duster stoker

First off its a 550hp 408 stroker engine 13.1 compression:mad:. I remotely mount battery in truck with 2gauge wire. after putting this new engine in, it will barely turn over. So I went out and bought a battery that has 980ca. Still doing the same this. wtf. Do I need to run dual batterys? do I have a bad ground? I am using a mopar performance high torque mini starter. Could this be a timing issue? If so any one have a link of how to wire in a mopar performance (6al) to factory? I also need to know the Proper way to drop in distributor and the distributor firing order. Its a 70-84ish block. I need help. Or I will pay for help. I'm in michigan
