Recommend cold crank amps?

I am going to be purchasing a new battery tomorrow for the '74 duster, I was wondering, what range for power should I be looking into? Duralast makes 2 that would work, but have varying CAs / CCAs.

They all are the same price, I just want to make sure I get the right one for that won't be underpowered or overpowered?

Option 1: Duralast Gold
Cold Crank Amps: 640
Crank Amps: 800
Reserve 110mins

Option 2: Duralast Gold
Cold Crank Amps: 700
Crank Amps: 875
Reserve 130mins

Part of me tells me to go towards the higher side but, not really sure? Should I even go with a Duralast, or is there a better option?

Thanks for the advice!
