LT1 into 83 Camaro Emissions?????
If I choose to eliminate the O2 sensors which the donor car had (95 Caprice) and loose the STFT and LTFT, how can I know what the fuel air mixture will be? Since the ECM won't know how to adjust the injectors to maintain that 14.7 to 1 mixture from idle all the way to WOT, how do you know what the A/F is? Will I only be in open loop and is that okay? Or should I just keep the fuel trim system in operation? Thanks guys.

Will it even run very long like that? Let's tie your ankles together and do a 5k. Keep the o2 sensors functional.

Thanks guys. I'm trying to get everything straight before I send the ECM out for reprograming. I like the fuel trimming system and need to do a little more research.

You have the rear o2 sensors tuned out since it should have been equipped with 4. Those aren't needed to run, they just monitor catalytic converter efficiency.
