Rocker arm shafts...torque specs?

[ross87t]

I can't remember them, and gnttype.org isn't working. Anyone? 35ft/lbs?

35 Lbs. ft for the rocker shaft. Here's a link: Bolt Torque Specifications Click on Factory Engine Specs in the menu. Courtesy of Vortex Turbo Buick Performance.

thanks jimmy.
One more question regarding intake.Is there an actual pattern to follow when torquing down the intake.Or is woking from the middle out fine??

 

[Topjimmy]

You're on the right track, I go 15 lbs; 30 lbs; then the final go-round at 45 lbs. Here's the sequence:

7-3-1-5-9

< Front

8-4-2-6-10

Ahhh...that's 25 ft lbs for the rocker shafts...on the torque spec chart the number in the parentheses is the ft lbs...number to the left is newton-meters

35 lb-ft is guaranteed to break a rocker shaft bolt.

22-24 is what you want to do.

Ask me how I know this.

A lot of sources has this incorrectly listed as 32 or 35 lbft (its actually 32 - 35 N-m so you need to multiply by .737)
