"modifications require greater than normal current draw For instance, electric fuel pump, high power ignition, and the biggest culprit, in my case, electric radiator fans".

i think somebody is pulling somebodys leg. anyway. these are his modifications, and he has a 185 amp. alt and need more. every hot rod here has most of these mods. and i dont think you need all that alt. 100A about as big as ive ever had, and i dont have no bat problems. now somebody have 2 -135A alt. you could run a house off this kind of amps. i can see that on your show car now.
