850 Cold Cranking Amps vs 710 CCA - The 1947 - Present Chevrolet & GMC Truck Message Board Network

So I went to replace my battery and specifically asked for an 850 CCA/1000 CA, to replace the battery that's in the truck now. Stupid me trusted the guy and sure enough when I got home it was a 710 CCA!

I replaced it anyway, but the truck wouldn't start! It was turning over fine, but wouldn't catch! So I swapped back in the old 850 CCA and it started right up!

Is this just s fluke, or does the engine really need an 850 CCA battery?

It's a 1971 Chevy Cheyenne, 3/4 Ton, 2wd with a 400 SBC bored .30 over, with a 400 Turbo Trans.

Thanks,
Rick
