Okay guys, need some help. In the process of figuring what I need to make my z street legal. It has a Holley Street Dominator on it right now, and this thread ( https://www.thirdgen.org/forums/afte...ke-please.html ) says there is no EGR, however this auction ( http://cgi.ebay.com/ebaymotors/Holle...Q5fAccessories )

My question is how do I tell if it is an EGR or a heater run off as the first thread indicates?

Sorry if wrong forum, wasn't sure where to put one on carbed intakes.

 

The manifold in the 'auction' (note that its Summitracing) has the provision for the factory EGR. Either will work, but you would need to do some work to make an EGR to function properly using the heat choke hole. The other is a bolt on, no hassles.
