I came across this on another website. I will take this as crap for now unless somebody can confirm. The upper intake is 89" everywhere else I have read.
Anyone heard of this revised torque on the upper intake?
I have a 2005 shop manual and it still reads 89 inch pounds for the upper (lower is only thing at 11lb).
Be advised that GM revised the UIM bolt torque figure in 2004 from 89 in-lbs to 11 ft-lb. The LIM bolts are still 11 ft-lbs. Follow the proper torqueing sequence as seen in the PDF file especially for the LIM. There are 12 LIM bolts and some are different size in length so do not get them mixed up.

Your car makes small children cry.
His dog ran away and didn't come back for a few hours on the first fire up too. It was awesome.
When babies cry and animals flee, you know you did something right
