I posted this in the newbie area and haven't got any replys so I thought I'd post the link to the thread here to see if I could get some help.

Just plug em if your computers tunned for no emissions.

70Nova SS

The hole behind your throttle body is for your EGR I believe and Street and Performance sells a trick billet thangy to plug it. Can't really think of anything else you could use to plug it. hotrodlane.cc is the web site

Or just go to the GM dealer and buy:

EGR block-off plate PN 12558346 for about $15.00; has a nice gasket included and mounts to the intake manifold

Buy the "LS1 Engine Kit Installation Guide" PN 88959384 for about $16.00 while you're getting the EGR block-off plate; excellent guide for swapping an LS engine

70Nova SS

ALot cheaper and you'll get it alot fast.
