Amazing video and information. The only thing I’m stuck here wondering why didn’t you tell us the foot pound for 9 and 10 just like you did for the rest of the bolts which you told us the degree and ft lbs
@@jorge56188 I’ll be purchasing another LS soon and will be doing a complete video series over the entire build no matter how small the detail I’ll make sure I put all the info in the next video.
I bought a Durofix 1/2" ANGLE digital torque adapter. $85 on Ebay. For use with existing 1/2" breaker bar. Just doing one 2003 LS engine. Positive reviews. Maybe upgrade if I get totally bitten by the LS bug. 1982 Volvo LS swap. Thanks for the well done Video.
Well, I appreciate you responding back, great video will definitely subscribe, I’m going to torque bolts 9-10 to 50lbs for final pass…. Going to send it

Thanks for this, much appreciated. Are the bolts 11-15 all the same size?
Yes
Great job on the engine.
I have 5.3LS L83 Cylinder heads. M12 X 1.75 X 135 bolts. Do you know the torque specs of mine?

What was the final torque spec on bolt 9 and 10 in ftlb
Everything is in the description.
Do you have to use the angle part?
With the TTY bolts yes. You can buy ARP bolts that are just a torque spec only.

I’m doing my right now but my torque wrench doesn’t seem to have the angle torque
And have the same bolts
You have to purchase one specifically for angles not all torque wrenches have it.

9 and 10 end up 50lb foot torque?
No, they end at 50 degrees.
I understand that both nine and 10 is 50° final pass but what was the foot pound on them????
Don’t know wasn’t concerned with final torque. Just following the the proper steps.

why not go to 65ft pounds and send it. thats what some guys do
I have the tool to do it to GM spec instead of just “sending it”
