Upper plenum bolt part #

[Skip Fix]

Any one have a part # or source for the upper plenum to intake bolts that have a stud on the top?

If you are referring to the fasteners that are used to fasten the upper intake manifold to the lower intake manifold on a 5.7L Vortec, then I do not believe they are sold invididualy. They are sold in a set, GM P/N 17113523. I purchased some recently.

As he said a complete kit, GM # 17113523. On GM Parts Giant. Look up intake manifold. In the parts breakdown a listing for bolt kit, upper intake. Shop around for a good price for new. Good luck.

Thanks guys!! Kit is even better. I kept looking up the intake on a few GM sites but never found a full intake break down that had those. Need alternator bracket bolts and PS/AC bracket bolts. Want all this on the new 383 to drop in when I pull out the old tired 350 350K miles and still going! Burns a little oil.

What is best intake gasket for stock manifold? I have a FelPro 1255 all composition thick one-not sure if water would seep through eventually. And a FelPro steel Rubber one.

Even on GM Parts Giant they do not have a diagram of alternator bracket diagram and which bolts go in what location. Have bolts listed.

I have an exploded diagram showing the upper and where what attaches, or got any Vortex's nearby? Snap a couple pics showing stud locations?

To find my parts, I use two websites in conjunction: GMPartsGiant and WholesaleGMPartsOnline. The latter has diagrams and you will need to know your RPO codes; with the former, you can narrow parts down to your VIN.
