Hey guys,

Just wonderin how many ft. lbs. of torque to put the bolts at for the intake manifold on an LT1.

thanx in advance...

 

on shoe boxes site it says 71 lb. in. first pass
35 lb. ft. 2nd pass

 

15ft lbs the first pass
35ft lbs the second pass

 

Thats 75 inch lbs, 35 ft lbs

 

...and that's right from the "book".

 

If you make the first pass 71 ft. lb. how can a second pass of 35 ft. lbs. do anything?

 

^^^^^^^^^^^

 

Thanks for the clarification

 

My intake is torqued to..... ?? I know many will tell you it's important to torque it but I NEVER do. On a composite intake I would but on an aluminum or iron one "I" don't think it's really necessary. ALL of the bottom end and the heads I torque but not the intake. according to the "book" you SHOULD torque damn near everything. Such as, plugs, headers, water pump bolts, and many more but do any of us follow the book? Shame on me...I know I don't.

 

If you can get the bolts pretty much torqued consistently then I don't see it as a problem, but if not then you stand a good chance of warping the intake. Do you at least torque the bolts down in a sequence (inside-out)?

 

Yes, I always do that to make sure the gasket seats properly. After you work on cars for a while (15 years+, I'm 32) you kinda get a feel for how tight they need to be. I have never had a problem.

 

I read ya. I've never trusted myself though.
