I have an 87 Merc 5.7 260HP (carb)...Assume alternator is stock and no heavy adder electronics load

Current battery is failing - need a new one that is spec's to the engine. Are there published "battery buying" parameters that sync to the engine type? A site that matches / recommends a battery size / type / cca / etc to this engine?

Thanks
