Thanks, since being a member of this site I've learned to ask before purchasing anything for my Mach 1, wished I had known about this site years earlier, would have saved me a lot of time and money with my trial and error method I was doing everything. The Autozone rep said 550 CCA was plenty because it doesn't get that cold here but even I know that's kind of weak to crank over a 351C that sits for long periods of time.
Thanks for the heads up. I checked consumer.org and their site indicates that the Everstart Maxx batteries are top performers and out perform most batteries costing much more. Swung by the Tumwater Walmart and picked up a 750cca battery with a 3 year warranty for $79.00.
