Hey Guys, Quick easy Question for ya's:

I have a 1971 blazer, stock 350, 4x4, manual steering, old school externally regulated alternator.

My alternator seems to be charging high, (17v on 2 diff testers -- at the battery), fried my battery, so I want to go to nappa /partsource today and buy a new battery and alternator.

Now I'm all about stock, but good easy power is more important -so the old alternator and regulator are going in the 'return to stock box' and I am asking the BOard for some of their awsome advice:

Can you point me in the direction of a '1 wire' alternator, that puts out higher amps, that will bolt up to the same brackets on my 350?

What would be most helpfull would be if someone could post a part number OR tell me what vehicle /year/motor combo would have the alternator I want.

One caveat: I am not rich, so please do not point me in the direction of 200amp, chromed bosch lol --- All I want is to run dual batteries(maybe), mild stereo, and a couple fog lights,

Thanks in advance for you advice!
