I am at the point in the build of my '32 Roadster where I am going to build a battery box set up in the trunk area of the car. I have decided to use a normal type of battery, opposed to an Optima type of battery. Anyone have a suggestion of a good Battery Group size to go with? I am considering using the group size of battery that lives in my '62 Chryslers and turns over their 413 big blocks all day long....as all I need the '32 to do is turn over a late 40's flathead. Thanks!!
