Hello all, I am currently working on a 99 GMC Savana 2500 with 5.0L Was wondering if some one could give me the torque specs for the upper and lower intake manifold (SPCI 8 bolt intake), and sequince. I have looked all over the net but cant find anything specific to the 8 bolt intake.

Thanks in advance Rob

Rob,

Hope I'm not too late to give you this info.

According to the Haynes manual:

Upper intake manifold studs:
Step 1: 44 in-lbs
Step 2: 80 in-lbs

Lower intake manifold bolts:
Step 1: 27 in-lbs
Step 2: 106 in-lbs
Step 3: 132 in-lbs

The sequence for the lower intake manifold is:


7 1 3 5
<- Front of engine
8 4 2 6

They don't show the sequence for the Upper Intake Manifold
