And don't listen to anyone in this thread about OBD1 vs OBD2 distributors and all sorts of crap. You can install an OBD2 engine in an OBD1 car without any modifications whatsoever.
If you installed an OBD2 engine in an OBD1 car then you wouldn't have a plug for that sensor on the Oil Pump...therefore wouldn't you have to do some modifications and get an OBD1 oilpump??
