Default Cam Sprocket Torque #'s

What is the torque value for the 3 cam bolt's ? I have a new Rollmaster TC set and plan to use the bolts with a little loctite over again. Thanks

26 ft/lbs on a LS1, 18 ft/lbs on a LS2 (although I installed a SLP double roller on a LS2 and its instructions were for 26 ft/lbs).

Why did the torque lower? ARP cam bolts says 25ftlbs and the ls7 spec says 22ftlbs . Which is it?

Go to ls1howto.com. At the top click on torque specs and there is everything you could ever need.... only stock parts though. No ARP values

Default Single bolt

Can’t see torque listing for single bolt cam in ‘07 Suburban. In the process of AFM delete. I bought all the components listed on lt1swap.com. He goes in to detail the differences of 1 bolt vs 3 bolt cams and what can be swapped. Just looking for torque spec....

Thx
Matt

Torque goes with hardware size & thread pitch.

What size & thread are they?

Thx RB,
I found it online yesterday at 55 ft/lbs. +55 deg.
The smart people at GM feel the need to add this 55 deg figure instead of just supplying the actual torque needed to tighten the bolt. Genius!!!

thx for your response.

That's because it's a torque-to-yield bolt. They, along with others like it, ALWAYS have a torque-plus-angle spec. And if you don't do it that way, it will not be torqued properly.

I believe you are both speaking of the SINGLE BOLT cam sprocket.

The OP was asking about a 3-bolt cam sprocket, which 26 lbft is correct. I would also recommend red loctite and safety wire just to be safe. Have fun drilling the bolt heads though, I broke a couple drills getting it done.
