#324008 Stay OBD1 for sure... better options for tuning. Put your OBD1 engine harness on the OBD2 motor. You'll need to change a few sensor plugs such as alternator, distributor, injectors. THere's conversion jumpers avail for the alt and dizzy or you can see if your obd1 alternator will fit on your new motor. You can also put an OBD1 B series dizzy on to keep everything plug & play.
There will be some sensors that the OBD1 harness & ecu don't use, just ignore those. (knock sensor, crank fluctuation sensor, some misc emissions)
