lots of good batteries out there now,,I do like the optima red and you need to get a real alternator if your going to run on the street, I`ve been screwing with batteries and alternators on my street car for years, and the best I`ve come up with is the red optima (because its lite)and a good 100 amp alternater, you have to find a way to run an alternator, sooner or later you will have a problem, and you wont be likeing it. just my oppinion ...I run a single red, and lots of fans and pumps, and it starts my bbc like nothing!
