    Whining alternator on my ‘94

    I will add this. I seriously doubt the "250 amp" claim in that Amazon ad. These alternators are capable of that with mods, but I doubt this one would put out that much. It should however, put out a solid 145 amps, and do so at low rpms. Vettepilot

    Whining alternator on my ‘94

    Here's the one I got. The bolt spacing is close to correct, and will fit with some grinding to one of the mounting holes, as others have reported: If you buy the incorrect one, for a car, you will see what this picture shows. The diagram shows the two different mounting hole schemes; narrow...

    Whining alternator on my ‘94

    Thanks. I believe I've got it figured out. I'm converting my truck to an AD244 heavy duty, high amp alternator. Caution to all doing this: The AD244 alternators for cars have a bolt pattern that is about 3/4" wider apart than the AD244's for trucks, and they will not fit. When converting...

    Headers, headers, HEADERS??

    I have GREAT luck with cheap headers. Last set on a Blazer did not need touched until the Mexico salt air rusted them clean through after nearly 20 years. I saw cut the flanges in two between each cylinder. Then I used TWO gaskets coated with silicone. Re-tighten twice after warm up-->...

    Headers, headers, HEADERS??

    I don't know why, but the factory OEM's were the last one to get the "memo" about how much a good exhaust boosts performance, if they ever got it at all. Someone will say "longevity". My last set of headers was the very cheapest I could find that I put on my 1980 big block Blazer. It was my...

    High output alternator

    Ok guys, I think I finally got the scoop on this, after hours of research. I am somewhat at a loss as to why this info was difficult to find. The TBI trucks sometimes seem like they're the "red-headed stepchild" and quite neglected regarding available info. Not all of us have Vortecs, even if...

    High output alternator

    Guys, is there two different mounting bolt patterns for AD244 alternators? I am trying to put an AD244 145 amp alternator on my 1994 K1500 GMC 5.7. My understanding was that there's only a minor mismatch that could be worked with on one of the two mounting bolt holes. Many posts I have read...

    AD244 ALTERNATOR UPGRADE--> HELP!!??

    Hey guys, 1994 K1500 GMC 5.7 Z-71 Getting rid of the worthless CS130 alternator and upgrading to an AD244 for all the obvious reasons. I've bought a genuine GM (supposedly) AD244, # GM 15279852, 145 amp alternator that supposedly fits GM vehicles from 1996 to 2005. I have about 4 various...

    1995 Tbi 350. Runs for 30 seconds then dies. Feels rough.

    It's a bit of a pain to test fuel pressure on TBI, so it's often not done. But with any EFI, fuel pressure is critical to check when trouble shooting. One note though. The fitting they sell to hook up a pressure gauge that swivels is very prone to leaking and that is super dangerous. I...

    1995 Tbi 350. Runs for 30 seconds then dies. Feels rough.

    Just a couple "off the wall" interjections here. Doesn't this have an "upside down" sensor? Actually, I am referring to the crash engine turn off circuit. If it doesn't get oil pressure info, the vehicle will start, but then stop. What is the fuel pressure doing through all this?? Vitally...

    "POSI-TRACTION questions??

    1994 GMC K1500 5.7 w/auto trans. We are in the process of fixing it up and haven't driven it much. It is supposed to have "Posi-traction" according to the option list. However, I happened to have the back end jacked up today, and when I turned one back wheel, the other one turned BACKWARDS...
