Default Alternator choice?

Running a stock ford alternator an regulator etc and was wondering what people use for alternator sizes?
1 wire 140amp? (one wire seems simpler...)
regular ford 48amp?

A 140amp alternator would give me peace of mind but how much drag will various alts have? Once the batt is back full the drag should be minimal regardless of size no??

Checking them out now. I'll get a 100+ amp one just so I won't have to worry between rounds!

Thanks, for the info guys!

I don't run an MSD in my race car which I guess is a big draw in amperage but I run a stock 1963 30 amp alternator in my race car with a small pulley on the damper and never have to charge between rounds and I run the electric water pump and fan between rounds to cool sometimes.
