want to do an alternator upgrade and i got some ?s

[bjohn07]

first off i am not running any ac and im using a flex fan, no electric fan. the only electrical addons i got are my guages water temp,oil, volt, and tach. mech fuel pump. not electric. sound system i got a pioneer deck and 4 speakers. no amp or subs. and i plan on keeping the hei ign system. so how much amps does a stock 86 chevy alt put out and do i need to upgrade?

80 amps max, and im being very generous
