    how many amps do you need? how many amps do you want? single wire self fielding or multi wire? there are plenty available in a stock form. biggest delco out there will be a 140 amp cold field unit for an IROC Z or police rated caprice or tahoe. bosch makes a 165 amp unit, but i couldn't reverse the catalog information to an application. some car stereo places have access to larger units, upwards of 285 amps, but they tend to have low life spans and require lots of rf shielding.

    88 up RV series Burbs and crews have BIG alternators. My 88 is rated 105 amps. It should plug and play if you change the pulley out. My buddy runs a Alternator off a road tractor. It's 190 amps and a really low RPM. It's very reliable becuase of the application. Problem is it's HUGE! Would have to make some custom brackets for it.

    Wrangler NW has a couple high-amperage units. One requires a special adapter bracket that they provide.

    What year is your Blazer (nice use of your profile /forums/images/graemlins/rolleyes.gif)?
    If it is a serpentine make sure you go for an alt that has upgraded bearings. The stock bearing are inadequate for the tension of the serpentine system. Almost every alt problem I have had was due to front bearing failure....

    I have a A/C delco from a series 60/70 truck. It's rated at 160 amp. It uses the same wire hook up as the standard alternater. It is the same width, but 1/2 inch taller. I elongated the upper mount where it bolts to water pump and spaced out the bolt that goes to intake. I used the stock lower mount AND the stock lower bolt spacer! This is almost a direct bolt in and reman was only 100.00! (for me anyways) I checked with the company's that make the on board welders and It is COMPATABLE with their systems.

    At first I had a custom built alt. I went to an AutoElectic shop that rebuilt all kinds of stuff and they charged me 100 bucks for a Tweeked &amp; Peeked 120amp bolt in alt. Well few years passed on by and the LED in my cab went out(Hellroaring) So my alt was dead(turned out too be the regulator after the fact) and I bought a 140amp PowerMaster One wire 140 amp fer 150smakers....two weeks later it died /forums/images/graemlins/angryfire.gif
    BUTT
    PowerMaster /forums/images/graemlins/usaflag.gif had great customer service and they replaced the Alt and the replacement has surived to this day(all last summer wheenin wich included at ride out to Moab and back /forums/images/graemlins/1zhelp.gif)

    Go junkyarding for one with a black back half instead of aluminum color. 99% of those are 140amp ones and are the same size as yours. Can never beat a Delco alternator.

    Other than that, go looking in large vehicles, especially those that had plows on them before. Like all alternators, they'll be stamped with their rating. A good chunk of vehicles with plows had 100 amp alternators. It seems a good chunk of firstgen S10 Blazers had 85 or 100 amp alternators.

    Ambulances are the best place to look for a high-amp alternator. Some of them have odd cases though.

    Other than that, look in any commercial vehicle like a fleet vehicle or a city vehicle.

    I would, but 1. Bubba doesn't win the good chit and 2. I've got to throw on the Ford 3.8L fan before the 'Fest and I know that my alt, which is dying in the first place ain't gonna push this fan. Don't know if it really can give ya an idea, but when I brought these fans home, the only wire I had laying around was 14 gauge. So I did a quick hook up and within 5 seconds, the 14 ga. was too hot to handle. /forums/images/graemlins/thumb.gif

    I sure wish y'all Valley peeps would remember these places. I called every friggin place in Fresno one day and found one shop that would do it, $160. Not my idea of dropping change.......Luckily for this the wife has given me a bigger budget (our budget talks are worse than politicians sometimes) so I can get the darn thing done...............

    Oh, I forgot, the flex fan got bent at Raines along with the lower radiator shroud (which has been replaced) shattered so I would feel better about having a straight fan for the road trip................

    hmmmmm now i have a question.... will be stupid but that is expected from me.... /forums/images/graemlins/rotfl.gif

    i just put a 1991 caprice police motor in my truck. ditched all the serpentine stuff and the tbi..... no i dont still have it.... i also threw out the alternator... was told that since my truck doesnt use that much power that the high output alternator would blow up my battery... is that true?
    cuz if not i know where i can get about 5 of them... so i should be able to find 1......

    just curious....
    thanks
