1972 Lt1 convertible w/AC restoration Intake manifold bolts

[Fred H.]

Presently my 72 LT1 aluminum intake manifold is attached with 12 shoulder bolts, the example in the TI & Judging guide shows it should be assembled using bolts with separate washers. I'm assuming the TI & Judging guide is correct? Looking for photos of correct LT1 manifold bolts if possible.

Fred,
You want to restrict your request for pictures to 1972 LT1. I believe the bolts attaching the front lifting bracket will have a different head configuration than the other attaching fasteners.

I believe that the ones holding the wire supports will also differ in head marking.
Typically there are at least 3 different bolts used on an intake if you count configuration and headmarks as differences.

Good catch Patrick. I forgot about the wire supports late last night. The TCS Solenoid mount will have a stud on the bolt head as well. I know who can provide some pictures, but it will take some time for me to get this done.

Yes, I figured the stud was "obvious" but...

Fred, Read through this 2012 post with pictures of an original 1972 LT1.
