how important is EGR for a daily driver?

[Clone TIE Pilot]

I know that, I was pointing out the vortec intakes do not have an EGR. I don't use the EGR but I do have one jb welded to my intake so the emission enforcers stay happy

http://www.summitracing.com/parts/nal-1 ... /chevrolet It certainly appears to have an EGR provision...

your right, it does have a provision for an EGR. They must have made that to trick the authorities. I have never seen that before.

As I said before, GM sells an external EGR line kit that goes from the exhaust manifold/header to a port on that intake. Here is a link I found. http://www.edelbrock.com/automotive_new/misc/tech_center/install/2000/2899.pdf

That is also the only Vortec intake with a dual pattern. Not a big deal with the new Street Demon carb but has a non sbc price of $325 to run a Qjet. I have been successful removing EGR on my non CCC Canadian 81 Delta 88 with the Olds 307, no noticeable pinging and a ton of miles, 425,000 km. With computer controlled timing, especially with something with a lot of part throttle timing, it would be a nightmare removing it. I am pretty sure I could remove the EGR on my TBI Olds 350 and would run fine, other than throwing a code. Only because the swirl port sbc has a ridiculously lazy timing curve, I am running 21 base to compensate for it. If you aren't on the computer, put it on as said for emissions but otherwise not necessary.
