Thanks,

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
