LT1 Emissions Delete
I am removing the emissions from a 93 LT1 corvette engine and wanted to know if anyone has documented this process. I did not find much info with the search. I have the engine stripped to the longblock for cleaning/painting and will be putting it back together soon. No emissions testing for this application. Thanks!

IIRC the only emissions on the engine is the EGR, a simple block off plate and program the check out of the computer. The stock exhaust manifolds have tubes comming off them, I'd assume you are replacing them with headers. Just get the ones that don't have emissions hookups.
THere is an electric AIR pump in the driver side headlight well, just remove it. thats the only external emissions system.
