So here is what i have.. 97 z with a water pump cold air and 3.73s. I just installed long tubes which i will never do again on an Lt1!!! I took off all my smog stuff and had a tune about two weeks ago to delete the air pump and rear o2s. I have blocking plates on the way as well as a Lt4 knock sensor. I need to get the car on the road for this weekend and i dont have any o2 sensors for the new headers. What do you guys normally do? I heard vette sensors plug in and are longer? Its already sunday and i need the parts!! Any advice?

 

If I'm not mistaken the 97 has a 4 wire O2 sensor. If that's the case that indicates a heated O2. Go buy some extensions and put the old O2's into the LT's and be done with it.
