'96 Caprice LT1 EGR removal...

Hey guys,

My old man just bought a '96 Caprice Ex-cop car with the LT1 for his street rod project, which currently sports a carburated 350. Problem is, the exhaust manifolds on the LT1 which have an EGR off-line will not fit in his car. So he plans to replace those headers with his current headers, which do not have an EGR off-line. So, he's somewhat planning on removing the EGR system completely with block-off plates. I've heard that this will trip EGR codes in the computer (not surprising) and indicate the check engine light periodically. Question is, will it affect the car's driving at all? Will it put the computer in safe mode? If it does, how do you get around this problem? Thanks!

Just thought I'd add... I'm in Alberta, Canada, so we have no emissions testing! It's also going into a 1940 Chev, so it should be emissions except anyway.

You can do just about anything you would like on the LT1 engine. You will still have to send out the PCM for reprogramming, unless you plan on doing the programing yourself. I removed all emissions on my 95 LT1 and had these guy's do the programing. If you need any other help I can answer just about any questions you may have.
