Alternator Mounting problems

[66mustang0103]

I have had a charging problem on my mustang for a few months now (ever since I got it back on the road from a full restoration). The car is a 66 coupe with a 200 I6. I do have a header installed. It wouldnt wanna charge with anything turned on but the engine. After a while I discover that my alternator being so close to my header was causing it to overheat. With a longer belt installed the alternator charges correctly but the belt is loose and squeaks and I have run out of adjustment room.

I was wondering if a 289 came with a longer alternator bracket? Or if another mustang came with one? I would hate to just guess and buy one from summit without knowing if it would work. Any help would be greatly appriciated!

Thanks Josh

What about using a different belt size? Im not sure if a bracket will actually work, doesnt a 6cyl. only use bolts to attach the alt?

The 289 brackets are different and wouldn't work.

How about using a A/C bracket for a I-6 that has
the alternator mount at the bottom, I have one if
interested leave me a pm

The V8 adjustment bracket is quite different. If it were mine, I'd weld an extension tab onto the arm you have, to make it, say, an inch longer. Might take a whole hour. Alternatively, a small sheetmetal shield between the header and alternator would cure the problem, too. Doesn't have to be a big box, I'll bet a flat piece 2x4" would do the job, attached to a nearby bolt on either the engine or the alternator.

Yes, you can certainly fabricate something if you have the tools,
hardware and ability to do it.

You could also make a longer lower mounting bracket along with
a longer adjustment arm to move the alt out from the engine.

Thanks for the replies, I will try to modify my existing bracket this weekend. It only needs to come out just a tad further and it will work! If not i will work on a heatshield!
