    What should my 74 Z have come with for a battery and what brand? Do they make a topper that is correct or one close?? If so, which one?

    I need a new battery and would like to get a brand and size that fits under the best option that is out there.

    I'm using this battery in my 70 Z28. 10" x 6.25"

    Originals would have been Delco R89S standard battery or R89W with optional heavy duty battery.

    So this style is correct.

    How can I determine if my car came with a R89S or W? I unfortunately do not have a build sheet. Was the HD battery paired with other equipment such as A/C or was it an independent option? My car is a non A/C car but has a 26" radiator (but that could have been added later too).

    I believe but do not know for sure that the HD battery was a separate option and the only way to fully determine if you had it was a build sheet. No changes in the cable or battery mount system can be seen.
    It MAY have been included with big block cars or maybe for cars destined for Canada (cold weather). The posts are a little fuzzy on this.

    Ok thanks,

    I'm not hung up on it being exact but figured if I need to get a battery anyway, why not choose one that works well with the right topper.
