20 ft lbs

 

Are you sure, vortech? I thought it was between 30-45ft/lbs.

 

I go 20 on the plenum and 35-45 on the base.

 

Alright.. I never really torque the upper intake, I just make it snug. The lower intake should be higher than 20ft/lbs though, in case thats what you were talking about.

 

AFR recommends that the intake manifold bolts should be only "snugged" in sequence.

13.510 @ 102 non juiced uncorrected

 

I go 42 on the intake and 18 on the plenum and runners.

 

GM says 35 ft/lbs on the lower intake, but what do they know about building F-bodies, right?
