Surely Optima-type batteries are a good choice for the lighter engines like the sixes and 120s, and the postwar cars. For the heavy prewar senior engines like the Twelves and 320/385 Eights, the truck/commercial Group 4 lead-acid batteries from NAPA and Delco have more cranking amps and tend to last 6-8 years and they would be my choice for those cars. An alternative for these heavy old engines would be dual Optimas wired in parallel for more cranking amps.
