what size and type of car battery do I need.

It's on the battery that's in the car. Open the hood to find out. While your there make sure the connections are clean and tight. Half the cars we see have zero maintenance done on them...

i was taught in mechanics that for every 1 cc of engine is how many cranking amps you need; for example. 350 needs at least 350 cca. parts stores will of course give you a much bigger battery than needed..seems standard nowadays.$$$$
