Ah is amp hours i.e. how long it can supply x number of amps, i.e. a 55 aH battery will be able to supply 5.5amps draw over 10 hours, and the cca is the cold cranking amps, tbh as said a 063 should be able to do what you need if your on a budget, the bigger battery is fitted to the v6 because its a bigger engine to turn over than the k4, again diesel has higher compression so they are always fitted with big batterys too
