I'd like to upgrade the alternator on my street/strip small block 69 Dart. Currently I'm running a square back two field and would like to up grade this winter while I'm finishing up my new engine build. the car has a Magnafuel 275 pump and a Digital 6 ignition, no electric fan or water pump but would like to have some extra capacity if I want to upgrade later.

What's a good simple alternator up grade?

Thanks.
