Getting ready for my alt. What would be the minimum size needed to keep the battery charged ? This is a basic roadster with no frills, gauges, lights ,starter. No radio,or heater.
 
30 to 40amp alternator would work....

More than run all you've got and keep the battery up without a hitch...heck most old GM's only had 30amp in the late 60"s....
