What is this hole?
After reassembling almost everything, I noticed that there is this hole by the dist on the pass side that is not covered. It is not on my stock intake either. Does anybody know what it is and if I should plug it? :crazy:

Hey DT,
On 86 and later cars,thats the EGR feed tube hole...my car has the EGR feed tube from the exhaust manifold to this intake hole to pass EGR gasses into the intake this way.
If youre not using the EGR plug this hole up.
Seems like your intake is for the late 86-91 manifold.

That's where the EGR tube bolts up.
Get a EGR tube gasket from your Chevy dealer and a blank off plate if you don't have the EGR function on the engine; I can't see if there is an EGR Valve under the plenum.
If you want to retain the EGR function get the EGR tube from your Chevy dealer.

Thanks for the info guys. I am not running EGR, so I guess I will fab something up to cover the hole.
Oh yeah, just for a disclaimer, the valve covers are already Polo Green and the plenum will be to. It looks kinda :crazy: right now. :D :cheers:

Why the 1.5 Roller Rockers??? Why not 1.6's??? :confused:
That #2 rocker set looks strange...What holds those Harland rockers in position???
And if your catcon has the air tube, it should be capped off, too...
