I wanted to get some advice from someone regarding a good 12v battery. I'm running a 12v Interstate battery on my race car, which is a 350cu.in. with 13.5:1 compression. It starts okay but after I make a run and come back for another run, it won't crank over. If I let the engine cool down (overnight) it'll crank over then.

What kind of high performance 12v batteries do some of you guys use? I really don't want to go to a 16v battery or have to run 2 12v batteries.

Thanks,

Ron
