Im looking to replace my LS with a newer LS and I was wondering if it's ok to run an obd I or obd II LS engine as an OBD 0 engine or should I convert to a later OBD? The giant Swap info thread says you can run them OBD 0 by using an OBD 0 ECU and dizzy (wich I already have running my current LS engine. Is this really an optimal way to run the engine or would I have to have my ECU remapped. I ask because it seems really easy to find OBD II LS engines as opposed to older OBD 0 engines. Plus a newer engine is more likely to have less miles on it. Thanks for any input.
