I posted this on the Impala forum too, trying to see if you guys have some definite answers.

I'm trying to piece together a set of bolts for my motor from old piles of bolts.

Do you recognize any of these??? Or do any of you have any pictures of a set of bolts for the accessory bracket?

The six bolts on the right are for the water pump.


1 - PS pump? - they're NOT the throttle body bolts
2,3,4 - dunno
5 - dunno
6,7 - maybe something for the alternator? one had a nut on it, hopefully for a reason
8 - dunno

#1 Sure looks like a throttle body bolt, if not it is your power steering pump.
#2 -4 Look like accesory bracket bolts. The bracket that hold the A/C and alternator.
The bolt with the nut is for the alternator.
The other bolts on either side look like the bolts that hold the water pump to the block.
The four bolts to the right are all intake manifold bolts. They connect the intake to the heads.

 

There may be some difference in bolts, depending on what body the LT1 was installed. That looks like a b-body water pump, so you should specify what it is you are working with (if you want to get guesses that are more in the ball park).

 

Unfortunately, I've parted out both B-body and F-body LT1's. I know that this is a wild goose chase and I'm fully expecting every "guess" imagineable, but that's okay. Eventually I'll piece it together.

I didn't post all the shorter bolts that probably go on the acc bracket. That would really throw things for a loop.

PS - I printed out the "shoebox" bolt guide and will post up my results later. And you're welcome to add my pics to your site if we ever get this right.

 

1 ps
2,3,4 a/c comp to bracket
5 may be the alt
last time i checked you only need two of 11,12,13,14 and four of 9,10
the rest i would assume bracket to block. that long one looks oddly long, but i have only messed with f's and y's. no b's

 

Oh, crap, A/C bolts - now we're getting somewhere. Going to check that now.
