small block intake torque sequence?
« on: March 24, 2007 - 06:26:51 PM »
Anyone know what the intake manifold torque sequence is for a small block?  :clueless: I've got to take the aluminum Edelbrock intake off the 340 in my Cuda because it is leaking oil around the back of it.  How much do I torque it down to? 25 ft lbs?  I want to be sure I torque it correctly so that I don't damage my intake.  Do you guys recommend using the gaskets or just silicone on the front and back of the block?  The gaskets have pushed out of mine and I was leaning towards using only silicone on these areas.

Do you guys recommend using the gaskets or just silicone on the front and back of the block?  The gaskets have pushed out of mine and I was leaning towards using only silicone on these areas.

I used only silicon on mine with the RPM and my father used only silicon with his performer and neither one of them have leaked yet.  Just make sure there is no oil on the surface before you use it.  The thickness of ours was about 1/2" wide by about 1/4" to 1/2" thick.  It is better for it to squeeze out than for you to have a gap.
Good luck  :2thumbs:

Here is a pic of mine.  My father used an orange colored version which looks better than mine.
