Works great in my 03 S10
Bought this alternator for my 2003 Chevy S10 ZR2 as an upgrade to the stock CS130D. The AD244 style is a direct fit for the bracket on the V6 Vortec engines, and is a common upgrade for the S10 and related vehicles. I have 2 electric radiator fans and a bunch of electrical equipment, was definitely too much for a stock alternator. This upgrade was desperately needed and totally worth it, my gauge is solid at 14v and no flickering dash anymore, even with EVERYTHING turned on. When installing a high output alternator, make sure to do the Big 3 upgrade at the same time so you don't burn up your cables (Google is your friend). Also, for my V6 Vortec, I had to get a belt about 2 inches longer than the stock size to run this alternator properly with my tensioner, because the pulley sits higher than the stock CS130D does. I recommend doing the swap in an auto parts store parking lot so you can easily find the right belt. AutoZone was great for me, they let me test fit 4 different belts until we found the right length.

Used this on a LM7 swap and my 87 El Camino. Along with the Holly plug that has a single yellow wire and resistor in it. I used it with my Aces jackpot EFI system, connected the yellow wire to a key on and it is working perfectly.

I needed a bigger alternator for running an electric fan conversion, a 10,000 warn winch and an electric cooler and the set up was bogging down my stock radiator to bad to run the winch. The new alternator dropped right in the stock location I did the big 3 wiring upgrade and now I'm making plenty of of power. Oh yeah and don't mind the picture half of my engine is missing due to doing a Cam swap and replacing all my gaskets lol
