I'm in the process of planning an engine swap for 91 Camaro RS from 305 TBI to 383 Stroker. The engine builder says it does not support EGR, so I assume there is not port in the intake for an EGR valve. Is there a way to defeat the EGR logic and/or plumbing that will still pass emissions? The car will be antique by my states definition of the word in 5 years and it may well take me that long to finish bodywork and engine swap so it may be a mute point. Are there any other gotcha's that anyone can prepare me for?
TIA - Jack

 

A tailpipe test probably isn't going to be done under any conditions where the EGR would be active. If it's a visual test, you can just bolt up all the EGR plumbing and maybe burn a chip to eliminate the EGR tests.
