I'm very space confined now so I need the smallest possible sealed Optima type batter which has the most possible CCA. This is going in my 30 Model A roadster. I'm hoping that with this broad base of hotrod owners I will get several suggestions as to which is the smallest, has the most CCA, and is still a sealed battery so I can mount it different ways. Price is not the issue...just getting what works best and fits in the smallest area possible is the issue. Thanks for all the help and pointers!
