Correct Alternator Bracket for a 454?
I can never assume anything but one COULD conclude that I would have the correct alternator bracket for a 454 based on the picture?
What I am not sure of is whether or not mine is cast or stamped on the lower support. Is that the ONLY difference. Trying to find a stamp on mine as I have power steering.
I figure if I am getting my incorrect alternator replaced with a 1100543 I should make certain I have the correct mounting bracket.

Actually I did and it is useless to me.
A bunch of spaghetti drawings with no index or color. It will NOT answer my question. I need to take a class on how to read this book. Nothing drawn in that book looks like the parts in my car. A bunch of sketches and diagrams.
Referring to the AIM does not help me one bit.

That is good news. I am looking for any stamps or something with a part number of GM part of 3882810 on my bracket but can't find any. I read that these brackets were the same from 1965-1974 for big blocks.
So your comment of it being exactly like what's on the 427 moves me in the direction that the bracket itself in my car may be correct. As for the nuts and bolts that remains to be seen. Thanks for the reply.

Looking so forward to getting that 1100543 shipped to me. The seller is awaiting the correct pulley so they can do a swap and then it will be sent to me. I am glad I am putting this alternator to rest finally.
But the next chapter has already started (no pun in intended-starter).

The AIM is a valuable reference, but I do not think I would rely on it to determine if a part currently on my car is 100% configured the way it was originally, at least for judging purposes. In this case, I think Marc has wisely asked those who may be in the know.

Most of us? I am not sure if you are implying anything but I thought this forum can be used for general questions. Several others are in agreement that the AIM can be confusing. In fact threads about this have been started. I only had my car for not even 6 months. If you expect me to have the credentials of a gm assembly plant employee in 1971 then unfortunately your expectations are way too high. I have come a long way but no way am I going to rely on a AIM to confirm correct parts on my car.

FWIW, another thing to check is the small vertical bracket coming off the front of the alternator.
There were 2 different ones. I don't remember what year it changed, but the bottom of it bolted to a different location. Sorry no pic of it.

Look at the exhaust manifold stud where the bracket is attached at the #1 cylinder. If it's a nice flush fit, it's a GM part. If it has a large gap because the mounting extension isn't flush with the stud, it's an aftermarket Chinese POS! I had mine on and off a dozen times while hammering the *^!#%%&*^%*$*$* thing so it fit.

I'm not implying anything, BV. All I said was that most folks find the AIM to be a good reference. Regardless of whether you know the AIM forwards and backwards, you should be able to look at the bracket on the AIM page and determine if the bracket on your car looks like it. If the bracket on your car looks like what is on the AIM page, would there be a need to think you had the wrong bracket?

Simply put, the AIM is just too disorganized and confusion for some especially, someone new to 1971 corvettes. Perhaps, later as I get more experience it will become a more valuable tool.
But there is no reason to not use this forum to have questions answered even if someone chooses to not even refer to the AIM.
same as my 73 BBC.
