Depends on what you are "cranking." The (stupid) rule of thumb used to be about same cranking amps as CID. When they first started out with the cranking amps rating, 500 was a LOT and would start any gas engine in any passenger car, in any weather.
It still will. That's still the rule of thumb, too. One CCA per CID. I think somehow, battery companies have slipped by over rating their batteries. Kinda like all them lawnmower and small engine manufacturers that were over rating their horse power some years back. I actually got 14 bucks from that class action suit. LOL
