Choosing a Battery

[WallaceMFG]

I'm getting close to needing to buy a battery for my Chevelle, and I wanted to see what batteries people recommend. I put an optima in my Torino several years ago and haven't had an issue with it, but I've heard that optima's quality has dropped lately. I've been looking at Odyssey and Braille batteries. The Lithium Ion Brailles are out of my price range, so I was looking at their AGM batteries.

The main thing I've been looking at is the PCA, but how much is enough? I know that the higher the better, but I don't wanna overspend. I'm running a mild 350 with about 9:1 compression for now, so does anyone know what would be a good battery choice? If it makes a difference the battery will be in the trunk.
