Would it be possible to mount a crank angle sensor onto an obd1 block? say like on a 94-95 block that was dropped into an obd2 integ

 

First off the sensor on the oil pump by the crank pully is the crank fluctuation sensor. And if you want the sensor on the obd1 block put an obd 2 b series oil pump on the motor you want it on and yes it will fit perfectly. bolt pattern is the same and so are the alignment pins.
