Hey Guys I have a 94 cobra that starts rough or takes many cranks. This leads to the battery dragging or draining rather quickly. My mechanic is saying my battery is not good enough or does not have enough CCA for my car. But when I take that battery out and put it in my 65 ford truck that has sat for months it starts it right up, same with a 67 new yorker I have. The battery is a Duralast Gold 610 CCA and 760 CA (90 reserve minutes). Is this not enough? I do not have a massive stereo system. The car is running a TFS stage 1 cam if that has anything to do with it.My questions are:Is my current battery sufficient?Is there a larger CCA battery I can get that will fit in the tray/area provided?
