If nobody comes thru with a quicker answer - I can get those numbers from
my 2000 Silverado shop manuals and send it to you on Monday.
I doubt the torque settings would be different between the engines...
my book covers the 4.8, 5.3, and 6.0 liters...yours is what, the 5.7?

Torque settings will also change if you are using engine oil or thread sealer on them.

It's the 5.7 350. I will be putting permatex type 2 on the intake bolts. Any help would be appreciated. Thanks. :cheers:
