lS1 emissions test? I'm planning on putting an LS1 in my '82 corvette. I was wondering if I'll have to put all of the emissions control stuff on the engine. I've read that the F body engines have emissions control stuff but the corvette engines don't. So will it still pass without the smog stuff? Does anyone know what the policy is in Utah for smog tests? Will they use the test standards for the 1982 corvette or for the year and make of the engine?
Here in Illinois, we're required to pass the emissions standards based on our engine model year. What's nice about the OBD2 is that here all they do now is plug into the dash and read the PCM for codes. No more rollers or sniffers! If the computer says it's clean - you pass.
That's the part I'm not sure about...if they do an OBD-II test, are they looking for no error codes or are they looking for "pass" diagnostics?
For example: mine has no fuel tank pressure sensor, so I disabled that with LS1-Edit. The PCM has no error codes set. During inspection, will that pass or fail?

'01 with no egr? Do you think I should go for an '01 engine just so I don't have to worry about it passing without the egr? I'm kind of worried about how they're gonna test/inspect my car with the new engine. I think they might want me to have all the egr stuff in tact even though the engine will be way cleaner than my 1982 350. So I think it might be worth it to just get the '01 engine that already has the LS6 intake and not have to worry about them not passing an older engine with an LS6 intake.

Does that mean you have to have the computer for the dash ?
