RE: IML: "Overhaulin" my 1970 - Alternator upgrade? Why?

[Kenyon Wills <imperialist1960@xxxxxxxxx>]

If one is doing an engine upgrade, but leaving most of the rest alone, why would an alternator upgrade be desireable or worth doing custom fab work to get?

 

 

Why do I want 85 or 100 amp?  What's wrong with "stock" 65 amp?

 

I do not plan any major stereo system - maybe something modest, but not a PA system of any kind.

 

 

This change didn't occur to me, and I can't see a reason to do it, but learning and asking questions is why I'm here.  Do tell....
