Hi Don and list, I bought the biggest case, most number of plates, largest cold cranking amps, and best warranty offered at Carquest. That was 2 years ago. The car starts in -15 deg weather and has never failed me. The secret is to double the cold crank amps compared to cubic inches. A 331 Cubic inch needs 600 cold crank amps to work correctly. The biggest I could find was a 550. I was worried at first, but it has never failed. Most of the battery companies have discontinued the big 6 volts except truck applications. If all else fails go to a truck repair center.
