4.3 vortec 99 bravada

[johnplogii]

Anyone have a listing of torque specs on these? I'm doing an intake manifold gasket & need specs. Searched the net & found a lot on s-10's but not what I needed.

Thanks

Looking at my shop manual for my '98 Blazer (which I assume would be the same 4.3 as the one in your Bravada).

Lower Intake Manifold bolt:
1st pass in sequence - 27 lb in.
2nd pass in sequence - 106 lb in.
3rd pass in sequence - 11 lb ft.

That doesn't seem like much so I called a friend who just done his. He said those are the numbers he used in December and it hasn't leaked yet.

Thanks David, I appreciate it. Hopefully it works, I am putting in a used motor because our intake gasket went & the wife got it hot enough to blow a head gasket. I told her to watch the temp guage & she reported to me that it got to the red then started running real bad . Anyway thanks for the help.
