If someone here lives in the area of Colorado where this is required and has some knowledge about it, I would appreciate in what you are able to share.
My wife and I currently live in San Angelo, TX and it looks like due to health and other reasons, it's going to be the best for us to move to Colorado in the front range area between Denver and Fort Collins. I've been looking at homes for sale in Weld County which I believe has the same emission testing rules as Denver does.
I have 2 classic cars. One is a '69 GTO that I'm in the last stages of completing my restomod on. It has the original engine and I installed an Edelbrock ProFlo on it.
The other car is a 1983 El Camino Choo Choo SS and the engine an LT1 (4L60e from a 1996 Impala SS running a '94 ODB1 ECM with 2 O2 sensors. I removed all the emission controls and discarded them. It has mid-length headers and 2 1/2" exhaust with an X-pipe and of course no catalytic converters.
From what I can find, the GTO will be exempt from emission testing but the El Camino will be required to get what they call an "I/M 240 dynamometer (treadmill) test".
My questions are whether there is a chance my El Camino would pass this test as is? What if it fails? Are there any easy modifications I could make to it to get it to pass or would they be involved or maybe not even practical to attempt?
I have no idea what I would be up against. I really want to keep the car and love it the way it is right now. I don't really want to sink the money it would take to by and install a crate E-Rod engine and exhaust. The LT1/4L60 has less than 30K miles on it and this car runs sweet as could be. Here's a few photos just so you can see how nice this car is and why I want to keep it.
