Default How many Alternator AMPs needed for big block FE

Hey guys

I am looking for an alternator for my 427FE and I found a period correct reman (correct C5AF casing), but it is only 55Amps and I am not sure it will be enough.

Here is what I am running (circut wise)

Earls foot box blowers (on relay)
FFR regular radiator fan (on relay)
Radiator push fans (on relay)
FFR Heater (newer kit with servo controlled temp)
FFR Wiper
MSD 6AL w/blaster II coil
Smiths mechanical gauges (except for tac, ammeter, fuel sender)
Seat Heaters (on relay)
Halogen headlights (not FFR supplied) on relay

Mechanical fuel pump
Mechanical water pump

Now I doubt I will ever be running them all at once, but do you think 55Amps is too low? I was thinking I should be looking at 95Amps or so. Don’t want the headlights to dim out etc.

Your thoughts? I wonder if I can put 95amp guts into a C5AF housing???
