Carburator?

[kaylee12801]

Full size 85 blazer...Is a Holly or Edelbrok (can't spell it) carb better? Also, any ideas of where to get some kind of a book? I checked the Haynes, but my truck looks a lot different. It has a Blazer 305 motor that purrs, a digital alternator, and a serp belt set up. Any time something goes, or I have a small problem, I have no Idea how to fix it. I also have an isolator block (2 batteries), and no one seems to know much about this. Someone please help.

If you ask a question, someone will answer. Are you asking about the carb, the alternator or the dual battery setup? Ray

I'm asking about all of it. Which carb is best? Do you know about the battery setup? And I need help with the alternator, and serp setup.
