Brackets and pulley I.D help.

Going through some boxes of parts and can't figure some of these out.
Any help is appreciated.
Group 1. These were marked big block. I think the top may be a small block a/c bracket? (3876222) The 6 could be an 8
Second, a smog adjuster? Not for A/C i am pretty sure.
You tell me on the last 2...

More coming...

Re: Brackets and pulley I.D help.

Last 2 groups:
The top 3 groove only has LT stamped on it
The next is 3996631 AO
And the alternator bracket as not as wide as most. Not for a long pump small block.

Last pic i know are small block, but looking for application.
3755820 BC
And the double is 3744043.

If someone with the correct books wants to take the time to look up these part numbered parts and I.D. them, i would gladly paypal $5 for your time. (little incentive)
Thanks for any help. Eric

Re: Brackets and pulley I.D help.

I'll give this a shot...Post #1 Group #1.. Small block lower AC bracket.. #2 and #3.. Smog pump mounting bracket and adjuster W/O AC.. (not sure if SB or BB without measuring bolt hole spacing) #4.. mid-late 70's long water pump AC bracket..

Post #2.. pulley #1.. not positive looks like SB short water pump with AC
#2.. long water pump small block .. #3 and #4.. later model long water pump with PS..
Are you sure the number is 3995648 AG? and not 3995646 AG? if so.. short water pump with AC..

Post #3.. 3 groove pulley.. no clue.. same on next pulley.. the upper alternator is late 70's to early 80's long water pump small block.

Here's a site to give you one app of the last two pulley.. (I am sure there are several more applications to each number)

Re: Brackets and pulley I.D help.

OK, we made some headway here. I think the second bracket in the first post i pulled off a 396 with a smog pump, but have nothing to compare it to.
So none of the pullies appear to be big block? These were mixed in with 3 BB crank pullies, so i was hoping i had some sets here.
The site you posted didn't agree with my computer.
I appreciate all the help so far and i will double check the number in question...
Eric
