the car still has the stock intake on the carbed LG4...should i use the EGR one then?

 

If you want/need the EGR valve to work, yes.

Better choice: Weiand Action + EGR-version.

Equally better but slightly more expensive choice: GMPP. Mine was a crate take-off, so was actually less expensive than either Edelbrock or Weiand.

 

Or how about the Weiand Stealth. idle-6800 rpms. That's what I use.

 

With EGR?

 

Um, well mine doesn't have EGR, I was assuming they made it. Though there does seem to be a port on the pass side that is closed off, that could be fabricated to work.

 

If you don't care about the EGR I have an almost new, less then 500 mile Edelbrock Performer Manifold, in PERFECT condition for $70, + shipping

That's the one to get!
