any body know what the torque spec is for the intake and exhaust manifolds are and i need to take my exhaust off so can i reuse the gaskets for the exhaust i just put them on 10000 miles ago thanks

 

bump!!!!!!!

 

If the intake bolts are 5/16" (take 1/2" socket) then go 35 lb-ft on them, this is what most intakes with such bolts call for. Dunno on the exhaust questions tho...

(*2)Tighten to specification in numerical sequence beginning with bolt No. 1, then tighten again to same specification in line sequence beginning with bolt No. 4. See Fig. 2 .
(*3)Coat threads with thread sealing compound.
(*4)Tighten to specification in numerical sequence beginning with bolt No. 1, then tighten again to same specification in line sequence beginning with bolt No. 9. See Fig. 1 .


This may help

 

24 lb-ft, darn - any idea why an IDI with grade-8 bolts uses less torque on said bolts than a small-block with grade-5 bolts? Seems kinda odd to me...

 

thats really odd i thought it would be higher

 

These are stock specs. Since I'm turbo charged, after I met the torque value I went an additional 1/8 or 45* of a turn on the intake manifold bolts.

 

i am turboing the truck tmw i am also building my own gp harness cause the old one is a crappy design i was thinking i would go 29 ft lbs with the intake i dont trust degrees

 

Don't trust degrees? Many manufacturers use that method for headbolts and such. Alot of inconsistencies any other way really. With those inconsistancies your 5 ftlb increase isn't increasing much hold. Just my experience, it's only an intake with 3/8" bolts so I'm sure it will be fine.

 

Oh, so they are actually 3/8" bolts, and not 5/16"? Then the low torque spec is even more odd then... Oh well, I'm sure he IHC people knew what they're doing on those. And yes the degree method works good, this is just how you set the preload on lifter with the rocker arms - well, never done it on an IDI, but at least on gassers this is how it's done, tighten to zero-lash then give it a fraction of a turn more and it's done.
