Well, he has the AGMs... and from personal experience, I know the overdrive pulley does work. Question is if it will be enough of a difference....?

The pulley is cheap and easy so I'd go for it and see what difference it makes for you....

Hey Jack is that the same pulley that you and randy are using on your L-N units? I'm going to assume so since you mentioned that this fits any alt that fits the 6.0

It is. In actually got mine from another source that I couldn't find earlier.

Ford 3G 6G Lincoln Alternator 8 Groove Overdrive Pulley Increase Amp At Idle | eBay

Most of these vendors have alternate diameters, the one I've used is a 58mm. I've gone back and forth stock and overdrive, but with a 230a it doesn't make much difference. Stock pulley is fine.

I was having the same trouble last March. I replaced the alt with one of those 200A units with a breaker and extra wire to the drivers side battery. 2 months ago this alternator smoked itself! I bought a 110A unit at a local supply to get me home. I left the 110A alone, it works fine. Then one evening I went to start the truck and it was as if the engine was seized. Had it towed to a shop. One new starter later, it starts like it's never started since I bought it, which is about 60K miles ago. (it has 190K on it now) The engine spins over like never before. The starter has been dragging since I bought it and I had no idea. With the 110A alt and new starter, I have had no trouble, even with frequent starts. My batteries are older ones that have been run down a few times. I ve had them checked and they are fine. The engine now cranks over as fast as a gas engine without the sparkplugs installed. I m amazed at the difference.
